UM Mest JET Black — Ceramic Quadbrid Bone Conduction IEM - vividsound

What we hear

Energetic & Technical

The Unique Melody MEST Jet Black shows you the recording rather than flattering it: tight, correct bass, voices a step forward, sparkly treble full of detail, and three bone-conduction drivers that open a huge, three-dimensional stage, ideal for classical, jazz and records you know inside out. Rough masters sound rough and the treble can turn bright, and the ceramic shells run large, so try the fit if you use small tips.

What others ask  about Unique Melody MEST Jet Black

Is the bass on the Unique Melody MEST Jet Black sub-bass focused or mid-bass punchy?

Neither is emphasised. The Unique Melody MEST Jet Black has natural levels of both sub-bass and mid-bass, and the bass is tight and correct instead of big. It shows you what's in the recording and adds nothing. If you want bass that slams or rumbles physically from a Unique Melody flagship, the Maven III Moonshard or the MEST Fortune are the ones to hear.

How do vocals sound on the Unique Melody MEST Jet Black?

Close and clear. Voices on the Unique Melody MEST Jet Black sit slightly forward with a huge stage opening up behind them, and the detail level is the highest I rate. Nothing is added to flatter a singer, so great recordings sound great and rough ones sound rough. The Unique Melody MEST Fortune is the warmer, more forgiving sibling.

Is the treble on the Unique Melody MEST Jet Black smooth, sparkly or sharp?

Sparkly, and bright at times. Two electrostatic tweeters give the Unique Melody MEST Jet Black a detailed, sparkling top end, and I rate it at the top of my treble scale. It isn't harsh on a clean source, but it's bright enough that treble-sensitive ears should try before buying. At 12.6 Ω it also reveals a noisy source, so I demo it on a HiBy R6 III.

Is the Unique Melody MEST Jet Black fatiguing over long sessions?

It can be, if you're sensitive to treble. The Unique Melody MEST Jet Black is even-handed and very revealing, which is an attentive kind of listening, and the sparkling top end adds up over hours on bright recordings. The ceramic shells are dense and run large, though the fit is relaxed. For long sessions I'd steer you to the Unique Melody MEST Fortune.

Is the soundstage of the Unique Melody MEST Jet Black intimate or wide?

Wide, and as spacious as anything I stock. Three bone-conduction drivers (which pass vibration through the shell instead of the air) push the stage of the Unique Melody MEST Jet Black wider, deeper and taller than the driver count alone suggests. Placement inside that space is precise. Live recordings, orchestral music and film scores are where you hear what the money buys.

Does the Unique Melody MEST Jet Black fit smaller ears?

Not easily. The zirconia ceramic shells of the Unique Melody MEST Jet Black run large and have real density, although the fit is relaxed and not tight. If you normally use medium or large tips you'll be fine. If you're on small tips, try it first, because fit is the main reason a set like this goes back. Book a session in Utrecht and you'll know in ten minutes.
