Just a little on the smaller size for my 7 3/8 hat sized head. I think they make me feel hot quicker when wearing them while working. I haven't totally decided if I like them or not.

Love these and they work very well. The only thing I wish these were able to do is produce more low-end. I wear these to work out and at the office where I can listen to music at a decent volume and still hear everything and have conversations. :)

No more beeps when I'm mute in a Teams call which is nice. This is my second set. I bought my first set when they were just starting out and I still love them. I wanted to try the new tech and it didn't disappoint. I would highly recommend these.

Absolutely what I needed...not the best for high volume environments but at least I can where them at my work and not have just 1 earbud in. And I can still hear my boss yell at me.

The product works as advertised. I have used the OpenRun Pro for Mountain Biking and walking and like the feel and functionality. They appear to be a quality product.

I absolutely love these. I previously had an older generation of shokz and I upgraded, mostly due to wanting the smaller band size. I'm so glad I did. I am so thrilled with these. 10 out of 10, I'd order again.

With any wind while cycling, I still use earplugs so as not to keep volume too high. Overall, I am satisfied with the Pro model. Not as much base as I like but enough to enjoy the music you love to hear.

I like the way these sound but people I talk to on the phone do not. I get complaints from many people. I do not think the work as well as the earlier models I have purchased.

I'M GLAD I GOT THE MINI - I MEASURED FOR A REGULAR BUT DIDNT WANT TOO MUCH BAND BEHIND MY HEAD SO I ORDERED A SMALL AND IT IS VERY COMFORTABLE! SOUND IS GOOD QUALITY AS WELL

Was advertised to have improved sound - base. Keep comparing the new open run model and the older aeropex model for the same songs. Can't hear the promised improvement.
