Juzear Nimbus

Sonic Compass does not grade gear. We plot gear and listeners on the same seven axes, so a review tells you where a product sits and you can see how far that is from where you sit.

I went in expecting another entry-level IEM hoping to be the punter's pick out of a sea of cheap sets. HiFiGo, the group Juzear sits under, sent me this one after I spent time with their team in Shenzhen. It is the US$60 version with the USB-C dongle. HiFiGo did not see this review or have any say in it before it was published.

All listening was on the white (default) nozzles with grey red-bore tips, from a dedicated DAP over the 3.5mm cable.

Where the Nimbus sits — Warm-balanced on the white nozzles, with lovely bass, clean mids and enough treble energy. The stage is intimate rather than wide. Comfort, Dynamics and Emotional Engagement are its strongest axes.

Bass — Deep and warm, and it never turns muddy or bleeds into the lower mids.

Mids and vocals — Nicely behaved: not shouty or forward, not recessed. The mids sit right in the middle.

Treble and detail — Present in spades with no sibilance or harshness, and plenty of detail for me. They aren't the end of the road for treble detail.

Stage and imaging — Not a huge stage, but imaging and separation inside it are excellent. I can pinpoint every sound within the smaller space.

Tuning nozzles — Three sets change the acoustic impedance. White is warm and balanced and was my pick, the most balanced presentation by a country mile. Black is a V-shape with more bass and slightly scooped mids, and I enjoyed it. Red lifts clarity and vocals with a peak around 8kHz, and it was too much for me.

Design, cable and box — Electroplated zinc alloy shell with a blue iridescent glass faceplate. It feels premium at 9.2g a side, and it fits my ears perfectly. The four-strand silver-plated copper cable is thick with no memory, and it's one of the nicest I've seen on an entry-level IEM. The tips are generous (I settled on the grey red-bore ones), and there's a pouch, a cloth and a USB-C dongle on the US$60 version. They're easy to drive from anything.

Nimbus vs Koi D1 — The Koi D1 is a similarly priced set I reviewed recently, with a thinner cable and fewer accessories. It has more treble definition and a little more resolution up top. The Nimbus has far more bass, and its imaging and separation inside the stage are technically better. Mids are similar, reasonably recessed but forward enough for me. The Koi D1 is more energetic. If you want warmer, with more bass and really good imaging and separation, the Nimbus is the choice.

Read this against your own profile — I'm a bit of a V-shape lover who likes detail and staging. The Nimbus on white nozzles sits warmer than I'd normally pick and still suits me. If you like warm, bass-forward and clean, it's close to a bullseye. If you want a V-shape, try the black nozzles. If you're bright and detail-first, a Koi D1 gives more treble definition, and the red nozzles add clarity at the cost of that 8kHz peak. If you want wide, airy staging, this is an intimate set.

Honest limits — I had the US$60 version and listened on 3.5mm only, so I didn't test the USB-C dongle and haven't heard the modular 4.4mm cable. I judged it mostly on the white nozzles and tried black and red only briefly. The Koi D1 comparison was by ear and wasn't level-matched, and I took no measurements. It isn't going to compete with US$200 to US$400 IEMs, and it isn't trying to.
