These headsets are falsely advertised as BONE CONDUCTION when they are not. They identify as X1 on Bluetooth and have extremely poor range. They were purchase on 17 Jan and in testing over two discharge/charge cycles, the battery run life is about 1/2 the stated performance of 8hours. The narrow size does not 'conduct through the cheekbone' ; there are slots on the sides that direct sound back to ear canal. For the original 1/2price, I will not be returning them b/c the shipment hassle is too high.

It's too small and the sound is just so so, not recommended

pretty low quality. poor fit. the volume buttons don't work on mine, they are physically misaligned in the plastic, and when I push really hard on minus I can get the volume to go up. left side on mine is noticeably quieter. they connect well and play music if that's all you're looking for? otherwise spend the money and get real shokz

It works. It does transmit sound through cheekbones. But it's cheap. Don't expect miracles for 8$ At the same time, it is quite amazing to get a functional bone conduction headset for such a low price! If you want to try it, go for it, but don't expect audiophile level!
