These are fitness earbuds first, so it’s not shocking that Beats prioritized a bass-forward sound over an even, studio-style profile. That said, the low end doesn’t drown everything out. Mids take a step back, but vocals and instruments still come through clearly enough to keep things engaging, especially during workouts. The 9.5mm drivers handle thump-y playlists with ease, and battery life holds up—roughly six hours with ANC on, stretching to 24 with the case. You’ll get another hour of playback if you skip ANC altogether. The case itself charges via USB-C and is water-resistant (IPX4), though there’s no wireless charging, which feels like a miss at this price point.
