Life changing
Absolutely brilliant, I use for swimming and cycling listening to audiobooks. As I do breaststroke I can stream from my phone at the poolside. When cycling you can still hear traffic so it’s safe. Pottering around at home you don’t get sweaty in the heat like with my over ear headphones. Thoroughly recommend makes exercise a joy.

Just brilliant!
Brilliant piece of kit, I've upgraded twice so this is my third one, customer service is excellent and the ability to record anything playing on your phone and play back makes it perfect!

Title: Clever idea, poorly executed — hopefully soon returned (and you should think twice)
Bought these because the concept is brilliant. In practice they’re a design that rewards only very specific ear anatomy — mine isn’t it. The pads sit on the cartilage, not the cheekbone, so at normal volumes they buzz against the skin and the sound is terrible. I tried every adjustment, headband and swim-cap trick, and they still won’t sit where they’re supposed to, not that I want to walk around with that look all the time.If you want bone-conduction that actually conducts through bone instead of vibrating your ear, look elsewhere. I’ve initiated a return and asked for a refund under my consumer rights — this product, as worn, is not fit for purpose. Consider this a friendly public service announcement: great idea, shame about the execution.

Great multi activity waterproof headphones with MP3 player
The quality of the bone conducting headphones was far higher than expected. They don't match hi end audio headphones but they are used in different applications.I picked these for the inbuilt MP3 player and the highest level of waterproofing.The Bluetooth connectivity with my phone is excellent and pairing is simple and quick.Getting the music onto the headphones was not, initially, straightforward as my IMac did not recognize the headphones as an external device. An online chat with the customer service department solved the issue, they send me a firmware update and all was well. I think a Windows PC will not require the extra steps. It was then a simple case of drag and dropping my songs into the storage folders in the headphones.In use they are perfect when walking, but the highest volume levels causes vibration, it's not a discomfort but noticeable.During my 1st run I thought they were bouncing on my head, they weren't but it took a while to get used to the feeling. During a race last week I didn't notice wearing them, I only heard the music.The main reason for buying them was that the race rules only allowed this type of headphones to be used as traffic noise can still be heard. Normal audio on-ear or over-ear headphones are forbidden.I also had the chance to swim in them, they are great. Maybe a little too much bass underwater but simply amazing.The customer service is fabulous, online and via email so very happy with the product and with the company that designed them.I score them 4.5 out of 5 only because the 3 operating buttons are small and quite close together. It takes a moment to locate, by feel, the one you want to press.I've not had the battery level drop below medium but I probably only gone 2 to 3 hours before charging.They are expensive but they are high quality. The manufacturer had a Mom's day (USA) sale and they were discounted when I bought them.No regrets about buying them at all.

One annoying thing
Much, much louder than the other well known brand, i like the weight because it helps the headphone stay on, they feel snug and secure on my head, also like the silicone band they supply as this makes the fit perfect. Wish they had supplied more than one. Now to the one annoying thing, they turn off incredibly quickly when using Bluetooth and you have paused the track, wish they allowed you to disconnect or at least a longer time before completely turning headphones off. The voice is annoying and I wish the setting went to Bluetooth first instead of playing from memory. All in all a good buy and I would repurchase

Good, but watch the charging unit. It was returned.
It was good until 6 months later the magnetic charging unit broke, tried everything as advised. Nothing worked , very disappointed, will now have to start all over again.

Not great for Audiobooks
If you want to listen to audiobooks then beware as the first word after a pause for a new chapter or even paragraph part or all of the first word gets lost.The headphones are supposed to remember if you selected Bluetooth and then turned them off but they default to the inbuilt memory when restarted. This is a minor frustration but their support tells me that it isn't supposed to happen.I thought that USB-A charging cables were now obsolete but this comes with one. It took my a while to track down a USB-C adaptor so that I could attach the headphones to my computer.Apart from this things, they do work with music and are comfortable but are not for me

Wonderful Product
My only complaint with this wonderful product being that in Bluetooth mode. The headphones would after approximately 5 minutes of inactivity power off, I was informed by H2o that this was a power saving feature and could be overcome by listening to music within this mode, unfortunately that was not an option for. Shame because the sound quality was very good in my opinion.
