Bought 2 of these. Love it when it works, but one of them quit working after only a couple uses. It will take a charge but won't power on.I love these headphones. I don't need to put things in my ear that hurt me always, as I have small ear canals.I don't know anything about bone conduction headphones before. So I researched this bone conductive tech, and compare a couple of pairs of bone conduction headphones. Finally, I choose this one. I like its appearance and it's super lightweight, it's only about 1 OZ. it fits my head perfectly. I feel very comfortable even wear it for a long time.The battery life lasted all day, nothing on my head or face or in my ear got sore from using these. I always wear it when walking, jogging outdoor. I can still hear “morning!" from others and then I can smile back at them. I like these feelings.The products were well-made and the material is very flexible. The sound quality is better than I expected. I had known the sound quality of these bone headphones is not as good as traditional earphones due to their open ear design. But it keeps you the ability to hear your surroundings. This is very important when you wear headphones outside. The earplugs included in the package could improve the performance of the sound, but you need to block your ear from noise from outside.If you don't like traditional earbuds and want to try something new tech. I would HIGHLY recommend these!Conduction headphones are a great concept but the reality is, they are speakers that set outside of the ear canal. On a low volume setting with the provided earplugs, the headset works great. The issue for me is when you increase the volume, the potential for other hearing what you are listening to increases significantly.Additionally, a downfall is the fact that earplugs are required to hear the sound better when a market item is the ability to hear your surroundings better as your ear canals are not obstructed. Being hard of hearing, this headset does have a slight edge in relation to hearing the sound on a low setting without causing additional nerve damage; however, conducive headsets have a long road ahead before they can truly be a soundless (externally) headset. Overall, of the conduction headsets I own (I own every BT headset you can think of ranging from $5 to $559) the price is right and sound quality is exceptional especially for those with a high frequency hearing loss.Sound quality is awesome as is volume control. Noise cancelation is moderate at the best.. Use them everyday and definitely would buy again!Too small for meThe fidelity of bone conduction audio leaves much to be desiredWanted a headset I could listen to podcasts and make phone calls with that wouldn’t occlude my ears and would allow me to remain aware of my surroundings. These started off pretty good... not ideal frequency response, but they sufficed. Then, over time, the max volume seems to have decreased... also other parties complain about an echo on phone calls. Mic quality is not great. I’d say it’s better than using speaker phone with your phone in the seat next to you... but only marginally so.The sound is good and being able to hear other sounds while using the headphones is a great feature. The drawback is that the controls can be difficult to use. Volume controls have not worked for me. When I try to use them the headset goes to power off. Even power on can be tricky since if you depress the button for too long it goes to power off. Also, repeatedly, they fail to pair with my phone and I have to go to my settings, delete the code for these headphones and then start it again. The battery life so far has been great. They play all day on one charge.I had a similar headset and it's been held together with duct tape, so I decided it's time for a new pair. Since I'm on a budget, I can't afford the bone conduction headset I really wanted and got this instead. I do have to say the sound is pretty good. I wear glasses and this headset fits fine.Update: Took off a star. The sound keeps cutting out. It reminds me of the old days of listening to the car radio cutting out. :(
