I should definitely mention that the sound is far better than I had expected. When I first tried these on, I thought they weren't working and I was still hearing audio from my TV. That is, until I took a closer look and noticed the TV was silent! Needless to say, I am very pleased with sound quality.
Granted, you should gauge your expectations when it comes to bass, as that is the main caveat of having such a design and form factor such as bone conduction headphones. Let me be clear that bass IS present, but only really at higher volumes, and in the form of vibrations at that (they'll definitely rumble your head a bit, but surprisingly that may even make them even better in my case). Other than that, sound is superb!
Overall, I would definitely recommend these!
