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!!!

The battery life is no better than the Aeropex, the music sounds muffed. The Aeropex has alot better sound quality and the battery last just as long. And can get louder the the Open run....and they lots cheaper

I purchased the OpenRun Pro ear phones for my husband and he loves them. These are an upgrade from the Aftershocks purchased 2 years ago that lasted all that time. My husband loves the sound quality. Pairing very easy. Overall great product

Excellent product. I am an avid runner. I used wire headphones for a long time; then tried wireless headphones, which never worked. These headphones are perfect!

I like the way they fit but they hurt my ears when I wear my glasses, and I wish they would read my text like some of my other earbuds do otherwise very happy with my purchase
