I'm very impressed with the sound quality and the fit. I have quite a large head, but I can wear these things for extended periods with no discomfort.
I suffer from a touch of conductive deafness - i've had surgery on my eardrums which although has deadened my hearing slightly, i still retain my potential for hearing. For that reason alone, earphones that don't need to go via my eardrums were a very attractive idea. And in terms of the sound quality, I'm not disappointed. My left ear is slighty 'deafer' than my right ear, so I've adjusted the left-right balance of some of my devices accordingly to compensate with my other speaker-type headphones and earphones. When I tried these bone conduction headphones it took me a while to realise the reason these seemed quieter on my right side was that I no longer need to adjust the balance and can put the slider back in the centre position. Well happy with that!
I've done a couple of mobile phone calls with them, and I can hear people very clearly and they say they can hear me perfectly clearly as well.
I've also tried listening to music and while they're probably not ultra-expensive audiophile headphones quality, they sound no worse than the usual earbuds that come with the phone, or the cheap boom-mic over-ear headset I've got.
All in all, I'm very please and would recommend these. If, like me, you have hearing problems related to the sensitivity of your eardrum rather than your inner ear, these things bypass your eardrums altogether so could be better than normal speaker-type headphones/earphones.
Even for people with normal healthy hearing, the fact you haven't got your ears covered means your still aware of other sounds around you while you're using them.
However, i have a few niggles with the design which made me to give 4 stars instead of 5.
First, you have to hold down the power button for a couple seconds to either power on (indicated by the LED lighting up blue for a couple seconds) or off (LED goes Red for a couple seconds). If you just pick these up off the desk, there's no way to know if they're off or on as the LED only comes on for a couple seconds when you're powering on or off. It would have been nice to be able to tell if they were off or on without having to go through a power cycle. Especially if when the phone rings, you have to power on (or off/on if they were already on) which takes a couple of seconds before you can use them to answer the phone.
I understand lighting the LED all the time might drain the battery, but, for example, a quick blue flash for a short click of the power button to tell you if they're already on would be a great improvement.
Second, the product description states that they have "Dual Noise Cancelling Mics". I therefore expected the mics to be built into the ear-pieces (headbone-pieces, in this case), but by tapping in various places, I can only find a single mic located in the volume up/down line switch on the cord. Okay, but be aware that the mic will be dangling down one side of your face. If you turn your head to the opposite side while your speaking then the mic volume may drop off a bit.
Third - and this is specific for me and may not be a problem for others - is that the plug is a right-angle type, not a straight one. I have a smartphone case that has a cutout for the earphone plug but the right-angled plug won't fit. I had to buy a separate short 4-pole extension lead (like this one - https://www.amazon.co.uk/gp/product/B01CNG1IRW/ ) which has a narrow round cylindrical plug that does fit through the hole in my phone case cutout. Like I said, this might not be a problem for others, depending on what you use the headset for or what your mobile phone case is like in terms of access to earphone socket.
- Work remarkably well (if you understand their intended purpose)
- Battery life is acceptable
- You can hear your surroundings, whilst listening to music
- Quite expensive in comparison to traditional headphones of similar quality
- Sound does leak in quiet surroundings
As you will have gathered these bone conducting headphones sit on your cheeks just in front of the ears. Sound is conducted through the bone. This means your ears are free from being blocked and you can hear your surroundings.
These were bought for someone who insists on cycling with one earphone in. I was not terribly happy about this and would rather that no headphones were used. However, these are a compromise and as such do a good job. Oh! And the person I bought them for thinks they are amazing.
Not recommended as a headphone replacement (about 2 star level). highly recommended if you must listen to music, whilst cycling or jogging on the streets (5 stars).
I don't have any comparison with any other bone conduction headphones, so I can only consider these as headphones in general and specifically as headphones for use during sporting activities. I have tried these running and cycling.
Firstly, regardless of what anyone might claim, the sound quality is poor. So if you're wanting to listen to music, look elsewhere (probably not at bone conduction at all because it's not likely that any bone conduction headphones are going to give decent sound quality). There's little to no bass, so music will sound tinny. This is fine for my purposes on the bike, but I did try listening to some music to get an idea of the sound. Also, for listening to music you're still likely to have to turn the volume way up and just because these aren't in or over your ears doesn't mean they won't damage your ears.
If you're planning on using them while cycling, they may not play nicely with your helmet strap. My helmet strap sits just in front of my ears which is, of course, where these want to sit too. I've managed to make it work, but it's worth trying them on with your helmet on. The same goes for sunglasses. Because these sit over the ears, they sit right where the arms of your sunglasses are probably trying to go. Again, I've managed to make it work, but it's not always comfortable.
The biggest complaint for me is the design. The battery pack is way, way, way too close to the end of the cable, which means you either always have to have it in the same pocket/bag/whatever as your phone or use a bluetooth receiver, or, as I've done, get a third party extension. There's another reason an extension is a really good idea - the cables coming out of the battery are perpendicular to the sides out of which they come. This means their lifetime is likely to be quite short as they'll get quite a lot of stress. And they're not replaceable. If the cables give up after the warranty (OK, that's got a relatively low likelihood with a 2 year warranty), you have to replace the whole thing. Unless you can get the battery pack apart and replace the cable yourself. The cable going into the headband is a worry as well. Instead of coming out at an angle (I'd have angled it backwards), it comes out straight downward. That means that when the headphones are packed away the cable is under stress. And since only a soft bag is provided, this means the headphones are probably often getting damaged. It's not clear why anyone would design something in this way unless the intention was to ensure the lifetime is as short as possible. Or make extra money out of people by selling things like hard cases, which Aftershokz does.
The other problem I've encountered is intermittent sound. There are two sources of this. One is moving your jaw. If you're inclined to sing along, expect the volume to diminish significantly every time you open your mouth because that lifts the headphones from the sides of your head. I found the movement required to lift these away is actually fairly subtle, particularly on my bike where the headphones are fighting with my sunglasses and helmet strap for position. However, on a long ride yesterday the sound just cut out for long periods (up to 30 minutes at a time). This may be a loose connection somewhere. I have to get them out again and play around to find out.
So, while these are not bad headphones for the limited purposes I had in mind, they're not good as sports headphones in general and I suspect they'll have a short lifetime due to the design flaws. Caveat emptor.
Unfortunately, due to them not being adjustable and not wanting to keep my finger pressed to the side of my face, they are not suitable for my head - either it's the wrong shaped head or it's too small, or the technology isn't yet far enough advanced to penetrate the bone without the added pressure from my finger. These little headphones are inexpensive for such advanced technology though and so perhaps as with everything they are great for some folk, but not suitable for others who may have hearing loss due to blockages.
They are very lightweight and easy to wear, come in a nice little pouch to keep them safe in a bag, and don't take long to charge. They probably sound as good as the earbuds supplied with pocket radios, etc., so one shouldn't be over critical of the tinny sound which makes classical music quite unlistenable whilst on the go. I don't use earbuds, so found the sound quality below par for an enjoyable audio experience. I would say for joggers/cyclists and walkers who listen to other types of music and have good hearing generally, these may well be a 5 star product, particularly with the ability to take a phone call and stop the music with one click (I only tested them with a Pure Dab radio so can't comment on the mic function). Also the ability to still hear traffic and other surrounding sounds would make these very useful for some people.
For me though, I get a better experience with an inexpensive and technologically-inferior gadget: a dual channel equalizer which fits onto any headphone with the standard 3.5mm audio jack. As long as the sound can be sufficiently cranked up on the music device to blast through a nearly deaf ear, the equalizer just lowers the sound on the non-deaf ear to match the deaf one. It is a bulky gadget though for out and about and has an extremely long wire, so I was disappointed that these Aftershokz Sports headphones didn't work for me.
I'd definitely consider purchasing from Aftershokz again when the technology is a bit further advanced for a better, less-tinny, sound experience, acknowledging that they would come at a higher price. Also an adjustable headband for smaller heads would be an improvement on the design.
It is with regret that I am returning these headphones. I won't be investing today and if anyone calls me:
These have the built in microphone and glad to say, all is good, they work well with the PS4 allowing gaming as normal. As they don't cover the ears it also means we can still be heard if we call; great at tea time :)
One small drawback that cannot be avoided is the fact that as this headphone type vibrates it also needs power; the microphone unit holds the built in rechargeable battery that lasts around 10 hours.
So far very impressed and glad my son is not wearing over the ear headphones all the time.
