V-shaped SA6 Ultra with more recessed mids and vocals. Sharper and more bass than SA6U but mids are buried in busier tracks.

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.

Like the Ultra, but slightly improved in all technicalities categories except for timbre where the Ultra takes the win because upper-mids/lower-treble are too dialed down for my tastes on the MK2. If you don't have Ultra and want one, the MK2 is the closest you'll get.

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.

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.

Similar to the SA6 Ultra but with more bass, airier treble, and improved soundstage and fit. QDC Anole VX tuning, excellent resolution, and great bass with a practical bass switch. Unvented design.

A more refined SA6u, with the freedom to boost the bass even more and costing less. Less natural upper treble at the cost of that terrific extension.
