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.

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.Yanyin HBB Mahina User Reviews
