After listening Bose headphones and other Bose earphones for many years; this products does need improvement on sound quantity. Idea is nice but requires many improvements including fitting.

I have open run already, I expected pro to be improved sound but it was not and it seems the battery does not last as long as open run. Pro is very disappointing. It seems like less of quality for more money. I am thinking about returning.

Good these for my friend and he loves them, he said how great they sound and for great. Large size. Only thing is you can't ride a golf cart the other person hears too much wind noise.

Love them! So glad I made the switch from ear buds. They are so light and comfortable and the sound is superb. They stay in place while running beautifully.

I have a very large head. That is not their problem... but I wish the loop behind my head was larger. They pull on my ears and hurt after a while. Especially whenever I wear glasses.

This is such an amazing product, hence I had to get one for my wife, she loves it too, she enjoys her workouts with them. And overall, just doing anything with them is so much easier overall, and a better experience.

I see the 8th generation is better than 9th generation, that my opinion, I use 8th generation and 9th generation , I'm talk for clarity in sound Everything is good but the quality if I use to call

I love these things! Makes the whole experience of running with my dogs more enjoyable and safer. They work great and stay in place. They are so comfortable that I can wear them all day. I think they're very stylish, too.

Got a pair as a gift. These are the beat ever! It's amazing how clear the sound is. I love that you can still hear what's going on around you. I will recommend these to everyone!

These are very comfortable. Great sound and call quality. One minor issue is they don't work great on airplanes due to the background noise but this is expected. I like to be able to hear whats going on around me. Great product!!!
