I bought and returned many wireless headphones like the Sony m3x1000, or whatever the name was , jbl, Bose etc but they all seemed lacking in the volume and bass area. Yes some of them had good sound quality but didn’t have the bass of the beats. The Powerbeats is the best of all i headphones I’ve tested I know there are more I haven’t also. I wouldn’t say there are the best tho because when I compare them to my old Powerbeats2 , they don’t have the volume and the power to match. If only they were just like them it would have been perfect, especially since they cost 249 brand new. Still a little disappointing for me.
