LetShuoer EJ07M VS BGVP Astrum

Youtube Video Summary

Letshuoer x HBB’s Kinda Lava retunes the EJ07M toward a neutral-with-tasteful-bass-boost signature, thickening the mid-bass versus the original’s Harman-leaning sub-bass shelf. The midrange sits essentially dead-on neutral with excellent clarity and micro-contrast, while the treble is well-extended yet notably safe for sibilance, occasionally showing a soft, sandy EST texture. Versus the stock EJ07M, this tuning feels more integrated and less “subwoofery,” though overall differences remain subtle.

The headline is the bass quality: firm attack, clean decay and addictive depth—easily among the top tier in the price class—without bleeding into the mids. Technicalities are solid, with decent imaging, but the head-stage runs a bit narrow and the overall tilt can sound slightly dark on airy recordings. Build is light metal with red shells and a handsome screw-top metal case; the stock cable feels basic for the price and the faceplate finish looks less premium than expected.

Fit is comfortable but may need SpinFit CP100 tips or a taller two-pin cable to lock in seal and stability. In comparisons, Sennheiser IE600 hits harder up top with a V-shaped incisiveness and wider sense of space, while Moondrop S8 offers brighter openness and BA-clean mids but less bass body. Kinda Lava threads the middle with balanced tonality, safe/detail-rich treble, and outstanding bass, culminating in a confident 5/5 verdict for listeners prioritizing natural mids and elite low-end over max soundstage.

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.
