Open Ear Wireless Bone Conduction Headphones,Bluetooth V4.2 Earphones Wireless Sports Headset Built-in Mic Sweatproof for Sports Driving 

I can't use them for long because they are too small; they give me a headache from size and bass rattle. Sound is great, but if you have a large head, this set will grind your skull behind your ears. I wish it could work out otherwise.

The sound quality is excellent only because it fits tight to my head. If someone has a large head this one wouldn't be for them. I stream music from my phone and the power level gets down to 20 percent in about 4 hours. I wish it had a longer life battery.

They were not loud enough for me to hear when outdoors around people and traffic on sidewalks.

Loved them, but speakers, could be closer inside, not stick out so far

They died after about a month is use. I used them three times a week and charged them regularly and they suddenly died after one month.

Nice

The photos of these being used were obviously fake, but if they were to scale, the people would have to have been child sized. Also, these aren't true "bone resonating". They are just close to your ears and you feel the vibrations, but no sound is actually being conducted. In fact, I would never use these in public because you need to turn the volume to max to overcome background noise. That means everyone can hear your music. Also, they get in way of glasses. Basically, it's garbage.

After running last week I put it to recharge on my laptop usb port and it never worked anymore. I tried to get in touch with the seller, but there's no way to get in touch with them. So, totally disappointed
