Very comfortable and sound good. My only complaint is that when listening to my GPS the first two or three words are frequently missed which often is take the exit or other important information and if I am dictating into my phone, the first two or three words are missed to type as well. This happened with the previous two sets that I've had, and hopefully they can work on that.

My wife and I purchased aftershock model, mine fits great, but my wife's head is smaller, so unfortunately her model slides off her head, and effects sound quality. Please make an adjustable model or different sizes based upon head circumference or some other measure.

The quality of sound is phenomenal. Also try listening with 1 or 2 earplugs. The sound fills your head. The fit is comfortable and secure. The battery is long-lasting as long as the volume is at medium or so. I love mine. Try them, you won't regret the experience. And they multi pair. I can listen to my tablet and take a call from my phone.

I received my Openrun Pro in one. They are very simple to pair with your phone. The sound has great bass and I love the different in each ear. I have used them to talk on the phone, the sound quality were great on both ends of the call. I'm very please with my Shokz's.

I'm 53 and have worked out over 10yrs now and never could find anything to stay on my head or in my ears during weight training. I do have a little hearing loss in my left ear so I really didn't like earbuds. But the Shokz Open Run Pro nailed it! I can still hear to speak to my gym friends and have a conversation. And answer a call if I need to with excellent clarity. Thanks guys. Great listening.

I have/had an older pair of Shokz, they got used and it was time to upgrade. The new pair are much better and the only thought for improvement would be the ability to size them a little better but that is a detail that doesn't affect the sound that much or the brilliant utility of them

Pros: Headphones stay secure on my head. Battery life is decent. You can hear background noise. Cons: If there is too much background noise, you can't hear the music. If you wear sunglasses and a hat, the addition of the headphones make it difficult to wear it all comfortably.

Absolutely transformed my training, the audio is super crisp and very true sound quality. The build of the headphones is amazing as well, I'm not concerned about them being damaged while riding. My only gripe is a small one and that's that the button to pause/skip is a little small and hard to push twice to skip while I have gloves on, minor inconvenience at that

Much better battery life than the titanium, but sound quality suffered. Sound is muddy and quiet. I have to take calls at max volume just so I can hear what the person is saying. Also not a fan of creating a proprietary charging system, it was better with a micro usb that could easily be replaced if lost or damaged.

Not as good as I wanted with my ski helmet. Integration with iphone and siri is not good. Cant control with voice inside helmet. Cant reach the control button when inside helmet. Much better for biking with a bike helmet. Still cant get good Siri integration.
