Some of the best timbre I've heard on an IEM to date with decent technicalities to match. Tonality is really good. Bass is neither too much nor too little - just enough to add the perfect amount of weight to the mids. It slams and punches when called for but never overwhelms. Mids are great. Treble is well extended but smooth with very good extension and air. It never gets sibilant or too bright. This is a cohesive IEM and almost nothing ever sounds "wrong." From a very subjective point of view, certain female vocals can sound slightly compressed, flat or recessed - in my opinion, it could use a smidge more upper mid elevation, but there are folks that really like this. Resolution is decent for the price but not particularly outstanding - details are there but there are definitely more detailed IEMs for the price. Imaging is fantastic and separation is very good. Overall the Supernova is in the running for most "natural" and "organic" IEM I've heard to date and I love it. Potential dealbreakers: this is an all-BA set so pressure build is something to consider. The woofer is vented so it's not too bad but it can be uncomfortable for sensitive ears. Previously Owned

Made to order - 60 days. Brilliant tonality with technical support, just lacking the last hair of detail. Transient sharpness and decay are on point. You will be hard-pressed to find better under 1k.

Super smoooth. TOTL dynamics and treble air - dunno how they managed this airy and smooth with only BAs. Very clean, no sharpness, or sudden peaks, endgame separation and detail. Only drawback is that the sub-bass is a bit meh, and that the sound isn't that "unique". Very safe all-rounder, and one of the best under $1000. Endgame set. Aside from the bass, everything else is better than Monarch MK3, MK2 still has better vocals, but the Supernova beats them when it comes to treble extention and smootheness - too bad it's impossible to get one lol.

TOTL mids. Most 3D and holographic staging yet. Imaging, separation, layering, and staging are all S level - only thing that's holding it back is the darker treble which can lead to softer notes vs, Diva, for example.The most immersive set for rock, alternative, ballads, and classical. An 07M that scales better with better staging. Great clarity and seperation. Treble is pushed back but still clear and evident in tracks (at higher volumes). Could use more low-end (but not an issue) and sharper note transients. Takes you on a journey. Needs to be listened to at high volume for the full effect.

Very engaging and very natural sounding. Decent technicalities. Instruments sound correct. Staging and imaging very good for an IEM. Very enjoyable. Leans dark and maybe a bit lacking in treble extension but also very easy to just enjoy the music which, at the end of the day, is what we even want from IEMs right? Previously Owned
