I got these in order to be able to listen to music while riding, without blocking other noise. I found the volume to be adequate and the sound is decent, given that you're not covering up your ears. But when I took them out on my local training ride, I found that when I was going faster than about 10 mph, the wind noise blocked out the music. It was fine when I was going slower up a hill.
I do find them comfortable, and have enjoyed using them to listen to news or music while working in the back yard. They are not bulky and stay in place well.
I like using music to keep focused while out riding, but wouldn't wear any headphones that prevented me from hearing what is going on around me. These allow me to still hear anything from a car coming up behind me on the road to a cyclist quietly announcing their presence as they pass me on a cycle path. Wind will get in the way of the sound, but any headphones will have this problem. These do need charging between longer rides, as I've found battery life at a volume high enough to hear the sound clearly (about 3/4 max volume on an iPhone) is around 4.5-5 hours, and the one time they've died on me it was fairly abrupt, but I had just arrived home. I would definitely recommend these for listening to music (and turn by turn if you are navigating with a phone) while out riding.
Incredible comfort! Easy to use, great sound quality. These are just a few of the thoughts I have had while using this product. Not having to shove something in your ear is great! They are so lightweight and comfortable, I sometimes forget I am wearing them. Great sound quality, even on a ride! With other headphones, you have to stop riding to take a call. I have taken calls while still in motion with these and the caller cannot only hear me, but doesn't know that I am on a ride.
The controls are fairly intuitive, most tasks are handled by one button. I like listening to music on some rides and can still hear traffic and the World around me. Do your self a favor and get a pair of these. Can't wait for the gyms to reopen so I can try the other pair I bought that are an MP3 player that you can SWIM with and listen to music. That is literally music to my ears.
