### ⭐⭐⭐⭐ Good earphones with downsides.
*by A***M on 17 July 2026*

Good quality and loud. They stay on while running just fine. Downsides are the fit, the piece on the back is pretty bulky so it won't fit everyone's ear. Also the touch button's are very awkward. No physical button, just have to double or triple tap a vague spot to pause/play or skip a track. No volume control.
