The
Tanchjim 4U is a DMT-4 LCP DD IEM.
The zinc alloy shells fit very well, they are small bean shaped designs akin to those Shure-type housings. There's a mirror-like faceplate, it definitely looks elegant, but may be a potential scratch or fingerprint magnet (so do baby them carefully!).
Unlike the run-of-the-mill tuning switch or nozzle craze, the 4U - as per its namesake - has four tuning options via an adjustable rotary bass dial, something similar to the Sennheiser IE80S. This involves using a screwdriver-like tool to turn the dial - it turns easily enough, but this will require good eyesight and steady hands.
So we have a legit 4 tunings, from a cold neutral bright one (blue graph), to a more bassy warm neutral presentation in the red graph. The other tunings lie within these 2 extremes:
After playing around with the dial, I preferred the red bassiest config (haha I like my bass). This isn't a basshead set even on this configuration, with a 7 dB bass shelf. Bass is punchy, though not with the deepest rumble. Speed and texturing are decent. The midrange is transparent and clean, with a 7 dB ear gain translating to forward vocals without shout. Treble has decent extension without much sibilance.
Pretty well balanced tonally, all things considered. Fans of something thinner and leaner can opt for the less bassy dials of course.
Timbre is excellent and ultra-natural, as expected of a single DD. When I spoke to the HIFIGO rep at Can Jam Singapore, the estimated release pricing would be sub $100 USD; technicalities are at least above average for a single DD at sub-$100 USD, imaging in particular is quite strong on this IEM. Will need to do further A/B comparisons against other benchmarks and report back, but this is a set worthy of consideration for timbre lovers that want something balanced and versatile.
