Sound could be better for the price, Fit can be uncomfortable for some ears
Very well made headsets. The sound is also terrific. I like the ability to sllow outside noise on my runs and rides. Personally, a little look large for my ears, they fit OK with smaller attachments but overall they are big.

Size, Music control functions.
recently purchased these and have been very happy. they fit great and sound better. good bass and seem to be very clean sound. I also like how they connect as soon as i pull them from the charger. Battery seems to last quite awhile but have only had them a couple weeks.

connect very easyfit and stay in place well
Sound is just ok, not as good as some I have heard. They do definitely stay secure. Easily the best ear buds to use for rigorous activity.
I bought these 18 months ago! I love them. They don’t hurt my little ears. Come with different size options and actually hold up against your real sweaty gal here!! Even surviving puppy teeth destruction even of 2020.
This product is okay. I bought them on special last year and I was somewhat happy with them. Sound was good but did not sit in my ear properly. I have tried each size earbud but did not help. They are quite bulky and after wearing them for a while my ears hurt.
