Fearless S8Z Reviews
Solid all-rounder with a safe, pleasing tuning. Crin Youtube Channel
A more aggressive S8P with even more grit/BA artifacting in the treble. Precogvision Youtube Channel
Night Oblivion Butastur Reviews
Similar tonality to the Supernova, please stronger female vocal extension at the cost of less refined treble, lovely midrange
I'd be careful buying it due to QC issues of others. But I enjoyed my time with it. Jaytiss Youtube Channel
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. Jays Audio Youtube Channel

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.
