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.

Youtube Video Summary
The Tanchjim Fission presents fantastic value right out of the box, largely thanks to its inclusion of a high-quality USB-C DAC cable with 3.5mm and 4.4mm terminations. The all-metal build feels premium, and the included cable is extremely silky and pleasant to use. A standout feature is the set of interchangeable nozzles that allow for sound tuning; the gold nozzle is the clear winner, providing the best balance, while others can make the bass less impactful. However, the fit can be a challenge for some as the shell lacks a pronounced lip, and the nozzles can be tricky to remove and replace.
Sonically, the Fission is extremely close to the more expensive and beloved Tanchjim Origin, offering a smooth, energetic sound with a tonality that is highly enjoyable. It provides a touch of warmth, pristine detail, and good air, making it a set that is easy to recommend and daily drive. When compared to other sets in its price range, it holds its own against competitors like the Dunu Kima (which has better fit and accessories) and the Kiwi Ears Quintet (which offers more bass), though the choice ultimately comes down to personal preference for tonality and the value placed on its tunable nature.
While it doesn't break the so-called "curse of the $150 IEM," the Fission is a strong contender and gets a full recommendation. Its few cons include a fit that may not work for all ears and a bass quantity that some may wish was greater. For those who value its specific sonic qualities, the excellent build, and the incredible package value with the included DAC cable, the Tanchjim Fission is a fantastic and competitive option that is very easy to enjoy.
