V-shaped SA6 Ultra with more recessed mids and vocals. Sharper and more bass than SA6U but mids are buried in busier tracks.

Overpriced as hell - I don't get the hype. Vocals are way too shouty with masking. Treble peaks around 10K with a dip in the air afterwards. Low-end is "good", but nothing amazing for the price. Detail retrieval and separation is competitive, but that's pretty much it. If you want a clean sound there are ALOT of other options for better like even the Blessing 3.

Similar to the SA6 Ultra but with more bass, airier treble, and improved soundstage and fit. QDC Anole VX tuning, excellent resolution, and great bass with a practical bass switch. Unvented design.

Like the Ultra, but slightly improved in all technicalities categories except for timbre where the Ultra takes the win because upper-mids/lower-treble are too dialed down for my tastes on the MK2. If you don't have Ultra and want one, the MK2 is the closest you'll get.

A more refined SA6u, with the freedom to boost the bass even more and costing less. Less natural upper treble at the cost of that terrific extension.

The NIGHT OBLIVION BUTASTUR delivers a natural timbre and cohesive sound, with its standout feature being a lush, dense midrange that excels in vocal and acoustic instrument reproduction. Vocals sound present and textured without shoutiness, while the bass offers weighty density over sharp slam, leaning slightly warm and creamy in texture. Treble remains smooth and fatigue-free, avoiding harshness even with extended listening, though it lacks sparkle for those seeking heightened brilliance.

Technically, it impresses with holographic imaging and strong layering, creating an intimate yet spatially convincing stage. The included modular cable is exceptionally high quality for the price, and the dual DIP switches allow subtle tuning adjustments—adding bass warmth or treble sharpness—though the changes are nuanced and require a tool to toggle. While isolation is good, the nozzle design risks internal debris accumulation, and the bass lacks definition in sub-bass decay.

Fantastic set for someone who loves organic sound and Mid centric tuning, incredibly underrated especially for an All BA IEM.

Pros
the Timbre and Mids on this are phenomenal, incredibly natural and lovely. the High end doesnt fatigue you after long listening session, and the venting is one of the best I've experienced, zero pressure build up. Pinpointing instrument is a breeze.
Cons
Treble lacks sparke, very subjective but quite a plain and boring faceplate (I find aesthethics important), and I wish the low end had a bit more oomph to it.
