What Are Bluetooth Bone Conduction Headset Phones and The Harm of Them?
What are Bluetooth bone conduction headset phones?Difference about the sound transmission way and wearing method.bone conduction headset phones are almost harmless, they are one of the healthiest headphones.
Did you know that a new type of headset phones is popular among young people now? They are Bluetooth bone conduction headset phones. They're pretty cool, and a different type of headphone than all the ones that came before it. If you haven't read it, follow my article to find out.
What are Bluetooth bone conduction headset phones?
Bluetooth bone conduction headset phones are headphones in which the sound generating unit is attached to temples. Their vocal units convert sound into mechanical vibrations, which cause bone vibrations, and transmit the sound to the auditory nerve.
They are vastly different from common headphones. Common headphones are air conduction, while the sound unit of them is a horn. When you play music, their horns convert the sound into sound waves, which travel through the air in your ear to your eardrum, causing the eardrum to vibrate and then send the sound to the auditory nerve, where it is finally heard by your ear. Bone conduction headphones convert sound into mechanical vibration when making sound, and directly transmit the vibration to the auditory nerve of the inner ear through the bone without passing through the air and tympanic membrane.
Because of this difference, the way Bluetooth bone conduction headset phones are worn is also different. They don't need to be plugged into the ear, but hang on the pinna so that the sound unit is pressed against the temple. Of course, there is another type of clip-on bone conduction headphones, which are clipped to the ear when worn, and then the sound unit will stick to your auricle. But the vocalization and delivery of the sound is the same for both.
The unique wearing method of Bluetooth bone conduction headset phones also brings many advantages. The most important thing is that they are very safe
What are the harms of Bluetooth bone conduction headset phones?
Conclusion first, bone conduction headset phones are almost harmless, they are one of the healthiest headphones. I analyze the impact of bone conduction on hearing, the brain, bones, and other aspects.
The harm of Bluetooth bone conduction headphones 1: damage to hearing? rumor!
Bone conduction headset phones damage hearing, this is a complete rumor! In fact, they can be said to be the headphones with the lowest hearing loss. They do not need to pass through the eardrum to transmit sound, and there is no damage to the eardrum. Their vibration waves are gentle and stable, and will not harm the cochlea.
The harm of Bluetooth bone conduction headset phones 2: damage the brain? rumor!
Bone conduction headset phones can damage the brain, another big rumor. It is believed that there are electromagnetic waves in the headphones, and electromagnetic waves will inevitably cause damage to the brain nerves. In fact, electromagnetic waves are ubiquitous in nature. Any electronic product has electromagnetic waves, and high-intensity electromagnetic waves will indeed cause damage to the auditory nerve and brain nerves. However, the electromagnetic waves of bone conduction headset phones are very weak, which is comparable to the strength of electromagnetic waves that exist in nature, so they will not damage the brain.
The harm of Bluetooth bone conduction headset phones 3: damage to bones? rumor!
They transmit sound by bone vibration, but the vibration intensity is so small that it will not damage the bone at all. At present, there is no record of any bone conduction headphones damaging bones.
The harm of Bluetooth bone conduction headphones 4: lead to temple pain? there are individual differences
Some people have mentioned that their temples are sore after wearing bone conduction headset phones for a long time. This situation has a lot to do with the wearer's physique, mainly trigeminal neuralgia caused by the individual's physique.
Therefore, Bluetooth bone conduction headset phones are not harmful to health, on the contrary, they are the healthiest headset phones. They are also safer and more hygienic to use and more comfortable to wear, which is why they have become more and more popular in recent years.
So how to choose Bluetooth bone conduction headset phones? You must pay attention to two key points: sound quality and sound leak reduction characteristics.Generally, it would be better to choose a team with deep technology accumulation in the field.Here are some excellent headphones for you all.
1 .Wissonly Hi Runner Bluetooth bone conduction headset phones
Recommended reason:
Wissonly is one of the few bone conduction headset phone brands that have mastered bone conduction vibrator technology, and one of the few brands in the industry that have sustained experience in using bone conduction technology to protect hearing. Wissonly Hi Runner advocate a healthy way to listen. They perfectly combine the principles of healthy hearing and bone conduction sound transmission, to create a non-in-ear and non-ear-damaging bone conduction headphone which can effectively protect hearing.
Due to the particularity of the technical principle, sound quality of bone conduction headphones is more difficult to be improved . To this end, Wissonly Hi Runner subverts the traditional sound quality scheme, makes a breakthrough to use the large-size bone conduction vibrator. Through structural optimization, the effective vibration area of the vibrator is increased by 35%, thereby improving the vibrator sound efficiency, making the sound more powerful.It also optimizing the direction of sound transmission, reducing sound loss during sound transmission, and making the sound more concentrated.
The skin-friendly silicone material of the Wissonly Hi Runner's body is a product that can be in contact with the skin for a long time. It is naturally a better choice and feels good to the touch. Because the entire headphone is made of skin-friendly material, it is very comfortable to wear. Even if you wear glasses, you can still hang it firmly on your ears. The headphone frame uses memory titanium, which has the advantage of being stretchable and lightweight.
2.Philips A7607 Bluetooth bone conduction headset phones
Recommended reason:
The sounding unit of the 7607 bone conduction headset phones use a 17mm vibrator, which makes its sound have good penetrating power. What makes me even more surprised is that Philips A7607 is equipped with LED night run lamp at the rear of the its body, which has three kinds of brightness that can be switched. It is suitable for wearing at night, which can make people around you perceive their own position and further increase the safety factor. The waterproof performance of IPX6 grade is fully qualified for waterproof work in daily life, and even can withstand a small amount of rain intrusion.
3.AfterShokz OPENRUN PRO Bluetooth bone conduction headset phones
Recommended reason:
Openrun Pro is the flagship product of Aftershokz, which is equipped with PremiumPitch 2.0+ technology, with good overall sound quality, rich low frequency sound, delicate intermediate frequency sound and strong high frequency sound penetration! It's IP67 waterproof, and it's basically enough to sweat during daily exercise. It's fine to get caught in the rain for a short time, but it's not suitable for swimming! In addition, it has no built memory, so it can't be used as MP3, that is to say, it can't be used where there is no Bluetooth signal.
4.earsopen PEACE TW-1 Bluetooth bone conduction headset phones
Recommended reason:
The earsopen PEACE TW-1 headphones can be charged magnetically through the charging case, which is small and convenient to carry around. The headphone shape adopts separate design that is achieved for the first time in the bone conduction industry. The headphone body is a T-shaped design, that adopts the clip-on wearing method. At the same time, it also supports IPX7 waterproof performance. When traveling on rainy days or running to burn fat, there is no need to fear sweat and rain erosion, it can be used with peace of mind.
The T-shaped structure design of earsopen PEACE TW-1 adopts the form of wearing behind the ear with curved support frame. It is more comfortable when worn. But because of the wearing method, the pinna will be a little uncomfortable after wearing for a long time. The sound quality is average, and there is a little sound leakage. But as an innovative style in the bone conduction category, it is also worth considering.
5.Nank Runner CC3 Bluetooth bone conduction headset phones
Recommended reason:
Runner CC2 is made of titanium alloy, with a body weight of 28g, and the overall wearing experience is good. The sound quality and sound leakage are better than their previous products, but they still need to be improved. The headphones also support high-definition call noise reduction, which is a plus.
The ability of this headphone is relatively average, and there are no special highlights or obvious shortcomings. As an entry-level bone conduction headphone, it is still qualified.
Among the several Bluetooth bone conduction headset phones recommended above, Wissonly and Aftershokz are my favorite brands. Compared with them, Wissonly is more cost-effective and worth buying.

How to get a better developing mindset
ewer: Amanda Chu A few years ago, I began to observe something in my own behavior that made me a bit uncomfortable. And that was that from the moment that I woke up to the end of the day, my life was a series of screens. I started the day with the thing that woke me up first thing in the morning, my phone, and so I sat there in bed watching various cooking videos on Instagram and bouncing around between a bunch of different applications. But then it was time to get out of bed and cook breakfast, and so the thing that I focused then on, in addition to the omelette in the pan, was the iPad that was right next to the oven. And then it was time to do some work, and so I went to a different screen which was attached to another screen itself. All the while, this little devil on my wrist was tapping and beeping and blooping and distracting me as I was trying to get important stuff done. But there was one particular offender out of all of these different devices that I wasted more time on than anything else. That was this dastardly thing: my phone. I could spend hours on this thing every single day. And so I decided to essentially, for all intents and purposes, get rid of the thing for a month. As an experiment, I thought, "I'm going to live on this thing for just 30 minutes every single day at a maximum." And so this is the amount of time I have for maps, this is the amount of time to call my mother, this is the amount of time I have for everything that I could possibly want to do, to listen to music, to listen to podcasts, and I observed what happened during this time. It took about a week to adjust downward into a new, lower level of stimulation, but once I did, I noticed that three curious things began to happen. First, my attention span grew. It was like I could focus on things, not effortlessly, but with much more ease than I could before this experiment started. In addition to this, though, as I was going about the world and especially when my mind wandered a bit, I had more ideas that my mind arrived at, and on top of this, I had more plans and thoughts about the future. Getting rid of one simple device led to these three effects. Why? Noticing this a few years back led me on this long journey to get to the bottom of what it takes to focus in a world of distraction. I pored over hundreds of research papers from front to back at my office. I don't know if you've ever watched one of those crime shows where somebody's solving a murder. And so they have this big Bristol board, and there's string attached to papers attached to memos attached to newspaper clippings - this is like what the state of my office was. I flew out to meet experts around the world who study focus; I conducted more experiments on myself until the point I had 25,000 words of research notes about why this is the case. How does technology influence our attention and our ability to focus? I want to start with the attention spans that we have. This is how we pay attention to the world around us and how much control we have over our focus. The research around this particular area is fascinating. It turns out that when we do work in front of a computer, especially when our phone is nearby, we focus on one thing for just 40 seconds before we switch to doing something else, and when we have things like Slack open as we're doing some work, this lowers to 35 seconds. But the reason that this is the case is not what we might think, after looking at the research. We think the problem is that our brains are distracted. But after looking at the research, this is what I've come to know as a symptom for the deeper problem, which runs much more deeply - it's the root cause of this distraction. It's not that we're distracted; it's that our brains are overstimulated. It's that we crave distraction in the first place. Our brains love these tiny little nuggets of information and social media and email and these things that we do over the course of the day. There's even a mechanism in our mind called the "novelty bias," by which our mind rewards us with a hit of dopamine, one of those wonderful pleasure chemicals, the same one we get when we eat and order a whole medium pizza from Domino's, you know, the same one that we get when we make love. We get that same stimulation when we check Facebook. We get this dopamine coursing through our mind. And so we not only crave distraction, but our mind rewards us for seeking out and finding distraction in the first place. So, this is the state of our minds today. We're at this hyperstimulated state where we bounce around between these bunch of different objects of attention that are very, very stimulating for our mind. And so I thought, "Okay, if the phone had this impact on my attention span, what if I lowered how stimulated I was even more, still?" And so, you know, this feeling that we experience when we go from being in a state of high stimulation into a state of low stimulation, it has a name. That name is called "boredom," (Laughs) you know, this restlessness that we feel when we have this super busy week and then we're lying on the couch on a Sunday afternoon, thinking, "Alright, well, what am I doing now?" So, I put out a call to the readers of my website and I asked them, "What is the most boring thing that you can think of doing? I'm going to make myself bored for an hour a day, for a month." And so I did some stuff that I still am upset about from my readers, to this day. Day one, I read the iTunes terms and conditions for one hour. (Laughter) It's actually shorter and more readable than you might think. Day four, I waited on hold with Air Canada's baggage claims department. It's very easy - This is the trick: if you want to make yourself bored, don't call the reservations department, call the baggage claim people because you're going to wait hours, if you ever get through at all. Day 19, I counted all the zeroes that I could in the first 10,000 digits of pi. Ugh. Day 24, I watched a clock tick, tick for one hour. And 27 other activities this month. Jeez. I still think back. But curiously, I noticed the exact same effects as I did during the smartphone experiment. It took about a week for my mind to adjust downward into a newer, lower level of stimulation, and this maps, curiously, on top of research that shows that it takes our mind about eight days to fully calm down and rest, like when we're on vacation, as an example. Our vacations need to be longer than they are today. But I also noticed that my attention span expanded. I was able to focus even more effortlessly because I wasn't surrounded by fewer distractions, but my mind was so much less stimulated that it did not seek the distraction in the first place. But the fun part were these ideas and plans that struck me that didn't before, and the reason that this is the case is because my mind had a chance to wander more often. There's a great quote that I love that you might be familiar with from J. R. R. Tolkien, where he says that "not all those who wander are lost," and the exact same thing is true, it turns out, with regard to our focus, with regard to our attention. If you think back to when your best, most brilliant ideas strike you, you're rarely focused on something. Maybe this morning you were taking a shower, or maybe some morning in the past, and then your mind had a chance to connect several of the constellations of ideas that were swirling around in your mind to create an idea that would never have materialized otherwise if you were focused on something else, on your phone, for example. This is a mode, especially when we do this deliberately, when we deliberately let our mind wander; I call this mode "scatter focus." And the research shows that it lets our mind come up with ideas, it lets our mind plan because of where our mind wanders to. This is fascinating. It turns out that when we just let our attention rest, it goes to three main places: We think about the past, we think about the present, and we think about the future. But we think about the past less than we might think, only about 12% of the time, and often we're recalling ideas in these thought-wandering episodes. But the present, which is a much more productive place to wander - we wander to think about the present 28% of the time. And this is, you know, something as simple as you're typing up an email and you can't find a way to phrase something because it's very delicate, maybe it's political, you go and walk to another room, to another room of the house, the office, and the solution hits you because your mind had a chance to approach it and prod at that problem from different directions. But here's the thing: our minds wander to think about the future more than the past and the present combined. Whenever our mind is wandering, we think about the future 48% of the time. This is why when we're taking a shower, we plan out our entire day, even though it hasn't started yet. This is called our mind's prospective bias, and it occurs when our mind wanders. If you're good with math, or maths, I should say - not in Canada anymore - these numbers don't add up to 100. It's because the rest of the time, our mind is dull, it's blank, or it doesn't have an idea inside of it that is rooted in time. But whatever it is for you that lets your mind wander, something that's simple, something that doesn't consume your full attention. Mine happens to be something that is not necessarily stereotypic of my age and gender demographic, but I love to knit. Knitting is one of my favorite hobbies; I knit in planes, I knit on trains, I knit in hotel rooms. I was knitting in the hotel room before this event today because it helps calm you down, it helps settle your nerves. And I come up with so many ideas when I knit, I have a notepad next to me. But whatever it is for you - it might be taking that extra long shower, it might be taking a bath, upgrading your shower to a bath so you can soak not just with your body but with your ideas as well. It could be simple; if you're at work walking from one room to another in the office - very simple change - but if you don't use your phone during that walk, your mind will go to the meeting that you're about to attend, it'll go to the call that you were just on, it'll wander to the ideas that are circulating, and it'll make you more creative in this way. It could be something as simple as waiting in line and just, I don't know, waiting in line. It could be getting a massage. You know, whatever it is that lets your mind - I love this picture so much - (Laughter) whatever you love doing. Here's a pro tip: Ask your masseuse to let you have a notepad in the session because ideas always come to you and you're always incubating things, so capture them so you can act upon them later. But I think, after doing this deep dive into the research, we need to make two fundamental shifts with regard to how we think about our attention. We think that we need to fit more in - you know, there's all this talk about "hustling." I'm an anti-hustler. I'm one of the laziest people you'll ever meet, and I think that's what gives me so many ideas to talk and write about. We don't need to fit more in. We're doing enough; we're doing too much. We're doing so much that our mind never wanders anymore. It's sad. This is when our best ideas and plans come to us. We need more space. If you look at what allows traffic to move down a highway, what allows it to move forward isn't how fast cars are moving, as you might expect, it's how much space exists between the cars that allows traffic to move forward. Our work and our life are the same way. The second shift: we like to think of distraction as the enemy of focus. It is not. It is a symptom of why we find it difficult to focus, which is the fact that our mind is overstimulated. I have a challenge for you. It's a two-week challenge, but it's a challenge to make your mind a bit less stimulated and simply notice: what happens to your attention? How many ideas do you get? How does your focus change? How many plans do you make? So, for two weeks, make your mind less stimulated. There are so many great features on phones, on devices that'll let us eliminate a lot of the time we waste on our devices. Use those features, not only to become aware of how you spend your time but how you can spend less so you have more ideas. Have a disconnection ritual every evening. One of my favorite daily rituals: I disconnect from the Internet completely from 8pm to 8am. My fiancée and I, we have a weekly disconnection ritual, a technology Sabbath every Sunday, so we can disconnect from the digital world and reconnect with the physical world, the real, actual world. Rediscover boredom - you don't have to do it for an hour. Please don't call Air Canada. It's just a world of hell. But rediscover boredom, just for a few minutes. Lay on the couch, and where does your mind go? And scatter your attention. You'll find some remarkably fruitful things in that attentional zone. If there's one thing that I have found to be true after doing this deep dive into this world on how we focus, it's that the state of our attention is what determines the state of our lives. If we're distracted in each moment, those moments of distraction and overstimulation build up and accumulate to create a life that feels more distracted and overwhelming, like we don't have a clear direction. But when we become less stimulated, when we make our mind more calm, we get the benefits of added productivity and focus and ideas and creativity, but we also live a better life because of it. Thank you so much. (Applause)

How to make transparent glycerine soap base from Scratch without Stick Blender
- [ ] Hi everyone, my name is Precious, today we are going to make a transparent soap base. I took advantage of an order to write this and the important thing to remember is to make this soap transparent and very clear without using a stick blender. This article contains a lot of details that will help you understand how to achieve this. Now I am measuring out my oils, I have to take out the one gram of coconut oil (560 grammes) because I don’t want to use a lot of fat, and there should not be any extra oil that will not be saponified by the lye solution so I am also measuring out my stearic acid (140 grammes), and I am going to burn my oil now. This is a double boiler method because I have discovered that that for me, it does expedite the process The crockpot slows me down every time I try to use it to make a transparent stroke base, so my oils are currently at 172.2 degrees Fahrenheit. In order for this process to work, your oils and light source must be extremely hot. You will not need a stick blender, so the lye water must be extremely hot to help you speed up the process. I have measured out my lye and water to mix together now I took my time to share some very detailed information, so only if you have the time to read it through to the end will you be able to understand everything. Now, I am going to mix this and, I am going take my mixture outside so that I do not breathe in the fumes coming out because it is not healthy. measure the temperature of the water and oil again, and it is approximately 177.6 degrees Fahrenheit. The temperature of my lye solution is 28.7 degrees Fahrenheit. combine light solution with oils since the July solution needs to be as hot as anything. You can just play some music if you feel like while making your base soap. One thing you should be aware of, though, is that you should not turn your back on your soap because if you do, you will find that there is a lot of mess on your soap due to the heat from your oils and living solution. being that hot, you do not have to look away from your soap. If you look away, you will find a huge mess on your counter. You just have to stir many times, stare this down to keep soap from exploding, and the reason it did not mess up was because the light solution was so hot—208.7 degrees Fahrenheit is a very, very hot temperature. Please be patient and read everything to have a good understanding on how to make a transparent base soap .stirred this for a while since you wouldn’t want the soap to ignite or to rise to the top and littered your workspace . Instead, just stir the soap to blend everything together .And sure, If you attempt covering it with plastic wrap, your soap vapor would dropped off. so you don’t have to cover it, instead stirred it down once again to prevent any mess Alright, you can go over it once more then wait to see what happens next. I believe this entire process took thirty minutes or around forty minutes to complete everything .If you not using a steak blender you have to wait for everything to melt. So after some minutes you see the soap is rising again. Go ahead and wipe your soap. check your water, and if appears you need to top it go ahead Well, you just need to stir this down once more for the last time Next, your solvent (glycerin, isopropyl), followed by sugar solution, will be added. cover it once more and wait to see whether it rises to the surface once more, and I believe it is. Yes, That is what occurs when your light solution reaches 208.7 degrees; you have no time to change course. Whoa, another vault I am not familiar with so quickly. You simply need to concentrate on it constantly until you finish it, or until you can add your glossary or ethanol or isopropyl to it. At this point, you can actually stop using the soap; all you can do is stand there and stare at it while keeping an eye on it. At this point, the task is completed and will not rise again so add 200 grammes of glycerin I used 70 supper pill which is 400-gram for this recipe, so go ahead and breaking down the chunks so that it will dissolve faster or you can make use of a hand mixer or blender, to blend it little to help speed up the process, however, that is alright. This will take some time, if you not making use of a machine it will take more than an hour to dissolve but if , you make use of a hand mixer it take about 15 or 10 minutes, at this point, you still feel like it is slowing down, that is normal In order to help dissolve all of the soup quickly you going to cover it again with heat from the alcohol. wait for the remaining small particles to dissolve, which should take about three to five minutes.also turned off your stove at this point because you do not need the heat anymore, so allow the vapour to help it out a little bit . Now that it is ready,get your mould set I usually do not add fragrance to this for my transparent surveys, but if you want you can just add any fragrance of your choice I normally avoid adding fragrance while making a transparent soap base because some fragrances just, well, how do I describe it, make the soap at the end and change its colour. We are done now, let me show you a little bit by simply popping the bubbles. For this particular one,you can leave it on your counter for about fifteen to twenty minutes before putting it in the refrigerator and now that it is finished, you can chop them if you are making this for a client ,or friends all you have to do is chop them into cubes or desired pieces . After much effort, you will be left with the finished product. Is it not beautiful? Oh, that is one amazing thing about creating a transparency, and if it turns out poorly, do not worry—sometimes the results are not as clear as you want them to be, so you have to redo them until are can make it as perfect as you want it, but this worked out well, and I really really loved how it came out. That is all for now; if you enjoyed it, please consider checking out for more. Thank you for reading, Goodbye.
