For music I would say the sound is slightly boomy/bassy as is the fashion, but not unreasonably so. I could get up to about 55 mph if I was driving WITH the wind, but driving into any wind, or a crosswind? i couldnt get over 40/45 without common sense telling me to chill out. I also thought it was abit pricey but this is by far one of the best out there in terms of sound, size and quality. That said, I have two minor issues with it, that might be specific to my hand or grip:1. After looking on Reebok’s website, the photos are more accurate there. The 3rd strap & new sole style is such an improvement. This is my first over ear bluetooth headphone, it is more comfortable to wear than the small earbuds. Ive had sandals like this decades ago, and I never thought I would ever find another quality product like this again for as agreeable a price! The frame was bent up, the wheels don’t touch the ground, the instructions were terrible and the assembly was a challenge since everything was visibly out of shape. The buds fit very comfortable in my ears.
