Alright, impressions time. These are with the Null Audio MKII cables. I was too excited to finally use them...I've had these in my position for over a month just waiting for my Qis.
Feel:
As these are my first pair of CIEMs, I really didn't know what to expect when putting these in. Admittedly I didn't really believe that they would isolate all that well compared to IEMs for some reason despite reading everything to the counter. In my mind, a hard acrylic shell without any kind of foam or silicone to form a seal of some kind just wouldn't do.
...well holy **** was I wrong. These things isolate like nothing I've ever felt before. They fit my ears like a glove. Once they're in...they're DEEP in there.
Reading about how CIEMs feel and FEELING how CIEMs feel are two totally different things
No discomfort at all for at least the 3-4 hours I've had with them so far.
Sound:
Lows: Bass quality is great. Sub-bass rumble is there when the song pushes it. Bass speed is also great, able to keep up with fast pumping electronic/dance music.
Mids: As someone who's been a happy camper in the V-Shaped department of sound signature, I've never really had a proper midrange to go with my colored bass and upper/highs. I honestly don't have a great ear for mids, but everything sounds crystal clear. The best I can say is that the detail is noticeably improved over what I'm used to.
Highs: Super crisp and bright. Again the enhanced clarity really shines here and things just sound great.
Compared to my previous daily driver in the B&W C5 Series 2, the bass is cleaner and more in control, but has a touch less "oomph". Still makes your head bob with the bass, but doesn't crush your ears as hard as some of the other IEMs I've used. The Qi's still bring it, though. I've returned IEMs that couldn't reach the levels I like and these are probably right on the line. Personal preference stuff, but a pure basshead may not like these as much as others with more impact. The clarity, isolation, balance, control...everything else is just leagues above my other IEMs.
Super satisfied with these. Was hoping the bass would hit a bit harder, but these will still easily work with my electro/dance style preferences.
Just a few hours in, but those are my initial impressions. I'm loving just sitting back with my eyes closed and letting songs roll over me.
...in fact, let me go back to that.
