Fiio FH19 VS LetShuoer EJ07M

Youtube Video Summary

Build and accessories are a clear win: a sturdy, comfortable, slightly translucent shell with MMCX connectors, a plush 8-wire cable terminating in 4.4 mm, and a premium magnetic case. As a 10-BA set around $1,000, it wears a tasteful black-and-silver faceplate and seals well without pressure issues. There’s a bass switch that nudges mid-bass upward; useful for taste, but not essential.

Sonically it’s a warm-tilted, cohesive presentation: male vocals come through full and rich, female vocals can sound a touch husky, and the mids avoid shout. Treble is clean and pleasant with a bit of 5–6 kHz energy that stays in check; overall clarity is good, though there’s slight hiss and the mid-bass can feel a little loose/flabby rather than tight. Stage and detail are solid, making this arguably one of FiiO’s better efforts, but the value is mixed—graded a strong A4 / S-: recommended if it suits the tonality, yet tough at retail amid fierce competitors; far more compelling on the used market or after a thorough demo.

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.
