Bland, but good tonal balance. Not terrible. Jaytiss Youtube Channel
Very pleasing and safe tuning with subpar technical detailing. Crin Youtube Channel
Comment: The only saving grace is the bearable tonality and bass for bassheads. Bass bloat with recessed, messy midrange
Pleasant, bassy, warm tonality marred by subpar resolution. Precogvision Youtube Channel
Abysmal fit and I couldn't actually listen to them without having to press them into my ears to seal. I'm sure they sound fine. YMMV. Previously Owned
Timbre benchmark. Fit is awful. Sounds a bit veiled and mids are below average for the price. Dethroned by Mele, even tho it has better timbre and treble extension. Remove the grill for better sound.

Great details and bass, so fun. Jaytiss Youtube Channel
