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.

The BGVP Astrum is a tribrid IEM with a 2DD+2BA+2EST array, using a coaxial dual 8 mm dynamic module for lows, Knowles BAs for mids/highs, and Sonion ESTs for the ultra-treble. This configuration, along with a four-way crossover, targets a balanced, resolving presentation rather than sheer bass quantity.

Early coverage characterizes the tuning as smooth, coherent, and broadly versatile—more “balanced W-shaped” than aggressively V-shaped—delivering clarity and air without pronounced sibilance. It is also repeatedly noted as not for bassheads: bass is controlled and musical rather than maximal.

Build and accessories are a clear focus: the shells are lightweight with preserved-flower resin aesthetics, and the unboxing is unusually elaborate; the stock cable is a braided 0.78 mm 2-pin with 4.4 mm termination. At an MSRP of \$699, the Astrum competes in an increasingly crowded mid/upper-tier where its strengths are tonal refinement, treble openness, and overall technical polish rather than visceral slam.

Similar tonality to the Supernova, please stronger female vocal extension at the cost of less refined treble, lovely midrange

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.

A pronounced 5 kHz rise creates "fake detail" and flattens staging; EST treble is capable but masked unless EQ reduces 5 kHz and lifts 10 kHz. Attractive build with lively bass and a competent EST treble once EQ tames the 5 kHz emphasis. Pronounced 5 kHz peak causes fatigue and a flat, congested stage, with bass turning boomy at higher volume; needs EQ.
Youtube Video Summary

A 2DD + 2BA + 2EST hybrid around $700, Astrum follows a low 2 kHz dip to avoid shout then a pronounced 5 kHz rise to restore energy, which for sensitive listeners reads as "fake detail". The result is a bright spot in the wrong place: presentation turns flat, 2D, and congested, with female vocals pushed forward while nuance is missing. Bass from the dual 8 mm drivers is lively yet grows boomy as volume increases, masking the contribution of the EST drivers.

Midrange texture and resolution feel compressed and digital, failing to convey natural timbre; the upper end fares better once the 5 kHz emphasis is reduced, revealing a competent EST implementation. Without EQ to lower roughly 5 kHz and add some 10 kHz, the treble transition lacks smoothness and stage perception stays small and 2D. For listeners not bothered by 5 kHz it can sound present and fun, but for those who are, this tuning choice undermines technicalities and realism.

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.
