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.

If you are looking for the most bang for your buck in terms of the costs of materials - this is it. But not the most interesting sound.

Holographic staging with an amazing midrange. Great bass texture and impact. Incredibly immersive and endgame for most. Has more sub-bass and treble air than OG doesn't scale as well.

Best Harman IEM under $600 (my unit is less harman), smooth and natural, great layering and tech, bass texture could be better/not as good as Oracle MK3, but overall very balanced and great all-rounder, also, amazing unboxing and accessories

Balanced subbass-focused tuning that borders the fine line between technical and boring, well extended treble that remains free of sibilance The lower midrange does not sound the most natural despite how funny squiggly lines look

Audionotions 8 Reviewer Score
Nearly the same as the Kinda Lava with very slight differences in the bass. More subbass at the cost of a tiny bit of midbass. Same great mids and treble. Possibly a tad less thick note weight than KL, but to be honest it's hard to tell the difference between these and the KL. They are both great IEMs. I prefer KL because I find it just slightly more neutral and balanced.
