great product but I sometimes have difficulty with comfort when using with a bike helmet/
I was very skeptical when these "bone conduction" headphones first came out. I saw more and more people wearing them, so of course like every cyclist I had to buy them too. I was immediately blown away by the technology that created an amazing quality of sound - all without illegally and dangerously using my earbuds in BOTH of my ears (California). My Spotify playlist is now both loud and crystal clear, and I can hear every essential sound that I need to focus on while riding: proper indexing of my gears when shifting, cars, conversations with my group. I don't know how it works, but it is phenomenal, and every rider in my group of 7 this morning was wearing Shokz this morning. I would never go back to normal ear buds - these things are phenomenal.
Battery last enough for a full day and the sound is amazing.
