Review on 🎧 Sainellor Stretchable Bone Conduction Headphones: Wireless Sports Headsets for Running, Driving, Cycling (Grey) by Peter Sullivan

One star off because the first set I received was defective: the left side didn't work. Luckily the Revain replacement was delivered with no problems and the new kit works! And I'm glad they work: they really are one of the best bone conduction headphones I've ever used. Surprisingly good low-end response without the vibration you get with most cheap pairs. The same applies to high volumes. Passed the earbud test (they even have a pair in!), so it's proper bone conduction, not just "speakers next to the ears". The MP3 player aspect is interesting, but I probably won't use it much. Good to have in case my phone starts going haywire. The management is perfect: +/- volume control, hold switches tracks back and forth. Very intuitive. The side button is easy to press and controls power (hold), play/pause (press), and mode change (something in between, which is somewhat ambiguous in practice). Overall really impressed. would recommend. I hope they improve their quality control because it should be five.
