When this hits it's very fun. Insane value.
Youtube Video Summary

Build & fit hit above the price: a sleek, glossy shell that’s a bit of a fingerprint magnet but sits securely with a small nozzle and generally comfy ergonomics; only the backside contour may trip up a few ears. The stock QDC-style cable feels plush and durable—decidedly “world-class” at this tier. No case in the box, but that’s a minor nit when the overall presentation feels A1.

On the rig, the Hydro shows tight channel matching and a versatile tuning via dip switches. The curve echoes heavy-hitters—think a tasteful 2.5–3 kHz rise, a dip after, and robust sub-bass with real treble extension. Comparisons point toward Monarch/Annihilator territory for tonality cues, while still keeping its own flavor: weighty bass and sparkling air without mid-bass bloat. The result is genre-agnostic confidence—female/male vocals, instrumentals, metal, R&B, gaming, even movies—all come through clean, lively, and engaging.

The “problem”? Not the sound—sonically it’s a standout—but the brand baggage some attach to KZ/CCA. Set that aside and Hydro reads like a reckless trend-setter: a double-DD + 8BA hybrid that punches way up, credibly sparring with sets in the $500–$600 bracket while costing far less. With its fit, tuning, and value—plus that excellent cable—this is an easy recommendation for anyone chasing a musical, detailed, and switchable all-rounder.

More uniquely tuned than other planars. Tamer uppermids, not as energetic, but still with great bass separation and tech. Timbre is good.

Warm tuning, really easy to listen to Treble isn't really well defined, separation between midrange and lower midrange isn't great either
