Well-resolving DD IEM with excellent treble control, though with somewhat weak mid-high harmonics.

Extreme basshead's dream. Incredible sub-bass shelf while maintaining midrange and treble balance.

Excelllent bass - simply excellent. Midrange could use some work, as could the generally average imaging chops.

A basshead set that's actually well-balanced for the most part. Extension on uppermids/highs are good but can get shouty, sub-bass texture and slam is impactful and satisfying - this is the set for most bassheads who don't want a crap ton of bass but still a good amount. Deuce better.

I usually don't like things that aren't all rounders but this might be the exception. Bass is incredible - best in class - great texture, fantastic physicality. Treble response is great too - pretty resolving. There is a noticeable recession in the upper mids, giving these a fairly U/V shaped sound signature - violins, for example, lack a bit of brightness/bite that I would hope for. But unlike other V-shaped IEMs, the mids aren't offensive. Incredibly fun to listen to. Probably the best single DD available. EQ highly recommended. Previously Owned
