Customer Reviews (4.8 / 5 · 5 reviews)

Grace L. ★★★★★

The SLAM module adds such a satisfying, tactile low-end punch without muddying the mids — perfect for checking bass response in a mix. I've been using them for a week and the clarity across the frequency spectrum is honestly unmatched for production work.

Alexander ★★★★★

The low end on these is unreal for an open-back—SLAM gives it that subwoofer punch without muddying the mids, and Manny’s tuning makes vocals sit perfectly forward. I’ve mixed on them for two weeks straight and my translation to other systems has never been this consistent.

Brian S. ★★★★★

I was blown away by the open-back planar magnetic design on these—the soundstage feels incredibly wide and airy compared to my old closed-back cans. They handle detailed mixes without any harshness, which made my late-night editing sessions much less fatiguing.
