Bone Conduction Headphones

Tune In Without Tuning Out

Aftershokz lets you hear music without having to cover your ears, so you’re free to hear ambient sounds around you.

Joggers can hear cars, animals, and other potential hazards, while office workers won’t find themselves “tuned out” from important conversations. Because the Bluez 2 set is Bluetooth-enabled, there are no wires to worry about, either.

Aftershokz use “bone conduction technology." It was first developed by the military in the ‘80s, and SWAT teams continue to use it today. By sending audio signals through
your cheekbones, the vibrations are carried to your audio canal. With normal headphones, sound goes straight to your ears, which can cause damage in the long run. Aftershokz bypass your ears entirely. The dual-microphone system even lets you talk, hands-free, on the phone.

With a high-tech look (a la Google glass), these headphones are worn on the back of your head. They are comfortably made with sweat-resistant materials. And since nothing sticks in your ear, they don’t interfere with hearing devices, and you can share them with other people without feeling creeped out.

This innovative audio is safe for your ears…and the rest of you.

    We introduced AfterShokz headphones because it's unsafe to run, bike, walk, or hike while listening to music with traditional earbuds or headphones. You can't hear traffic, barking dogs, or other warning noises. Using bone conduction technology to deliver sound with nothing in, on or covering your ears, AfterShokz are safer, more stable, and far more comfortable to use whenever you need to stay in touch with the outside world. Ask away.

    Wow - these are so cool. I always feel so out of touch with my surroundings when I wear my earphones. I feel like someone is always sneaking up on me! :) One question - how much can the folks around you hear? When I play music on my noise cancelling headphones on the airplane, I find that if I'm "jamming out", the people around me can usually hear it too. I really dislike noise pollution so I'm hoping these are better at keeping my music for my ears only.

    The AfterShokz bone conduction technology relies on creating vibrations that move through your cheekbone to your inner ear. When the transducers are off your head, the vibrations are moving the air, creating air conducted sound waves much like the speakers do in your home stereo or car stereo. You can hear those air conducted sound waves. Even when you put AfterShokz headphones on your head, the vibrations produced are so intense that some air around the transducers is being moved, creating audible, air conducted sound we call “leakage”. At low to moderate volume levels, the amount of leakage is minimal. At high volume settings, some people close to you will be able to hear your music. Because of this leakage, a few skeptics questions wether AfterShokz are really conducting music through their bones. Here’s the best way to prove that bone conduction really works. Put your AfterShokz on your head, turn them on, and plug your ears (ear plugs or your fingers will work). Without any ambient noise coming in through your ears, you will now experience bone conduction as the sole source of sound.

    This is my question too. In the video demo the noise is audible while speaker is demonstrating the headphones.

    What you are hearing is the demo of the cardboard box. Bruce took the AfterShokz off his head and put them on a cardboard box to demonstrate how bone conduction works - the box is your head, and the AfterShokz vibrate the bones in your head to create sound - that's what you are hearing in the video. At normal (medium volume levels), you have to get VERY close to the person wearing AfterShokz to hear what they are listening to. At high volumes, there is some air leakage. But it is less than what you get from traditional earbuds.

  • Donna
    4/17/2012 1:30 PM


    What I heard was at 1:09, not when the headphones were on the cardboard box but when they were on Bruce. But perhaps it was his being miked? Anyway thanks. Less than traditional ones is good!

    Hey Donna. Watched the video again and saw that you are correct. However, Bruce did have them cranked up and he also had a very sensitive microphone in close proximity. Under normal circumstances and at normal volume levels, it's hard to hear any leakage.

  • Jesse

    @Lori & Donna -

    That was my first question too, I put them on and asked others if they could what was playing.

    Bruce definitely had his music cranked in the demo (I bet in part to make the box amplify the sound more dramatically). With casual listening, both with the phone and while sitting in our quiet office (usually!), the sound is not audible to those around you.

    I will say that making a video about sound is always tricky -- sound records differently than it sounds in real life - but I wear the Aftershokz everyday at work now and am definitely a fan.

    I've had problems with neck bands lifting off when I move my head. Is the band flexible or hard? Also, what is the return policy if have an issue with the band?

    Would love these for work so I can hear people behind me instead of sneaking up.

  • Dennis

    @Bonnie - The band is flexible in that it moves in and out and it can be skewed diagonally. We have a no questions asked return policy.

    4/18/2012 4:46 PM


    Yes... we have a lot of customers who love AfterShokz because they do not have to take their hearing aids off, which, I understand, is quite a hassle... they simply put on the headphones and play their music or podcasts.

    I have hearing loss in one ear. However, my hearing nerve is still functioning. Would this enable me to listen to music in my bad ear?

  • dennis
    4/22/2012 2:40 PM


    If the choclea is not damaged and the nerve connection to the brain is intact, there is a good chance that AfterShokz will work well for you.

  •  Ann
    11/15/2012 12:28 PM

    @dennis I have single-sided deafness with nerve damage, and use an osseo-integrated device that allows me to hear sounds on my deaf side by passing them thru the bone to my good ear, so I am familiar with this idea. What I think would be great about these headphones is that they might allow me to hear music coming from two different spots on my head and might allow for a more stereo experience than I can get from ambient music in one ear plus the OI device.

  • Janie
    5/19/2012 8:58 PM

    Looks very cool, but do they work with glasses? I don't wear contacts -- too many allergies -- so prescription glasses or sunglasses are a must.

  •  dennis
    5/21/2012 3:41 PM

    @Janie I wear them with my reading glasses (plastic frames) and they fit just fine. I've seen some huge frames on sunglasses that could possibly cause some fit issues. As long as your frames are "average" thickness, AfterShokz will fit.

    How is the sound for those around you? If these are worn on a plane, do your seatmates hear what you hear more than they would w/ in-ear headset?

    @ Joan Eisenstodt - That was one of the first questions the first time we featured AfterShokz, too. See both Jesse's and Dennis' response above to be assured that these are not going to bother your neighbors.

  • Dennis

    @ Joan Eisenstodt

    Joan, the answer depends on the volume level of the AfterShokz. There is some sound leakage because the transducers that vibrate your bones are also vibrating the air. At low to mid volume, the leakage is minimal, making it hard for anyone sitting next to you to hear what you are listening to. At high volume levels, there is leakage, just as there is with traditional earbuds. Some of the new planes have fairly quiet engines that allow me to use my AfterShokz at low volume levels.

  • Dennis

    7/24/2012 12:53 PM

    @ lisa

    The in-line microphone allows AfterShokz to work with iPhones (and most smartphones). You can take and make calls and the quality is so good (built-in noise canceling on the mic) that no one will know that you are not speaking through the phone's mic.

  • Dennis

    7/24/2012 12:56 PM

    Whoops, I forgot to mention that the button on the control box allows you to take calls and, when pressed, interrupts whatever music you were playing. The music resumes after you hang-up the call.

  • Stephanie

    My daughter has an underdeveloped ear on the right side & has no ear canal in that ear as far as we know. These would be great for her if there was a way to wear them without hanging them over the ear. There are a lot of people who are missing one or both ears who would greatly benefit from these. It would be awesome if you developed another way to wear them.

    Thanks for this comment. We have heard from a number of people who are in the same situation. Looks like an opportunity for us to develop another model in the future, maybe with a headband that goes over the top, more like traditional headsets.

  • Stephanie
    7/24/2012 1:16 PM

    @Dennis Taussig, that would be great, especially if you developed kid-sized models. I am connected to a Microtia/Atresia support group, so I can help you find testers. :)

  • Leslie
    7/24/2012 12:58 PM

    My question as well... will these work w/my iPhone ... (driving in the car) and do those on the other end hear just as well with the mic as with the ones that come with the iPhone?

    No one will ever know that you are using the AfterShokz. They will think you are using the phone. Our customer service department uses AfterShokz. All the callers are really surprised by the great quality when we tell them.

    I have a huge head (I wear a 7 7/8 hat). When I have tried to use the "behind the head band" type headphones before they've been too small. Have you tried these with folks who have big heads?

  • Dennis
    Dennis – Special Guest
    7/24/2012 1:16 PM

    @ JeffG

    If you have a really large head, the AfterShokz will not fit well. We will be addressing this issue in the future by making the headband larger.

    Can this be used with an FM receiver? We have an elderly friend who needs to use the FM system when in church, but she doesn't want to use a regular headset because it presses on her old-style hearing aid.

  •  Dennis
    8/17/2012 5:49 PM

    @ Marilyn

    Without knowing more about the receiver, I can't be 100% positive. However, if the unit has a standard 3.5 mm jack, the AfterShokz will be able to connect to it and it just might work for you.

    I have bought sooo many headphones that are supposed to work with smartphones and they sound great. The problem is once you're actually using them you can't use any of the in line mic functions unless you have an iphone. This irritaes me to no end, as I personally dislike apple products. You say these head phones will work with most smart phones if they don't can I return them? Also are they at low enough decibal levels to be safe for children? My daughter loves her music and I don't want her to have tinnitus like I do.
