Sound is good. At first the sound seemed somewhat muffled but after awhile it sounds abit better. Also, if you really turn up the volume towards the high end you start to feel the vibrations on your skin which is a bother however, it makes me crank down the volume which in turn is better for the ear drum. Right? Over all I enjoy these much better than my Apple Buds. Also, love battery time and quick charge a BIG PLUS!

Love the light weight and battery life. Very secure on my head during activity. Volume is not great (though better after tech support talked me through doing a hard reset), so I feel like I really can’t usefully listen below about 50% volume. Both music and podcasts sound good.

I don’t feel like I can hear the sound well at all. My old pair of a different model were so much louder and sat snug against my head. I tried to file a question and do an online chat but I never hear back. I can’t listen to podcasts or books because the word are so low. I tried resetting them like the troubleshooting suggested. Kinda regret the purchase.

First time user of bone conductor headphones. They are great. Very comfortable to wear. Don't even know they are there most of the time. I wear glasses and they do not interfere. Would recommend to anyone, especially if you're like me and are tired of ear buds falling out. You can even wear ear plugs in a noisy environment and still hear your music.

The sounds is great but the real highlight is the comfort. All day wear with no issues on my troll sized ears and jumbo head. The sound quality is better than expected from previous models. If you keep in mind the application of headphones like these, I'm sure you will be very satisfied.

Although I have 5 stars for for they are a bit right around my neck. It is a bit of a thicker neck but also over the ears gets tight if on for several hours. I really like the sound and the levels the speakers have. Threes phones are so easily pout on and taken off and charge fairly quick.

The audio quality took me by surprise when I first tried on my OpenRun Pro. It was a weird experience to hear sound so clearly without an in-ear "bud" or headphone. The experience running in these for the first time was super smooth with a simple connection process and a comfortable on head feel. Through my entire run the OpenRun Pro was secure and totally seamless with no drop off in the connection. Plus the battery life was great and everything worked as expected. I Especially like the travel case. Thank you Shokz!!

The upgrade to the Openrun Pro is not substantial as I expected. Improvement is the sound quality, weight and comport. I was disappointed in the sound level seem to be lower and the battery life was not as much louder. I compete and wear Shokz daily. Possibly I am overusing which is leading to a average of 2 years and they stop functioning. This has not stopped me from a new purchase. 2020 my Openrun lasted 2 years. A warranty exchange a month before expiring. Stop working. 2022 same issue after the warranty. I upgraded to Openrun Pro only cause of the Black Friday Sale. I am not getting 10 hours of music and calls. Maybe if the volume is very very low.

The only problem I have when you do directions on your phone. It cuts out at the beginning.

I bought the refurbished and the quality is excellent!!!
