Audionotions 8.5 Reviewer Score
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

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

Immersive soundstage. Euphonic, lush mids, and inoffensive treble. Lacks incisiveness and upper mids can get a little intense. Cons: Price.
