Shuoer H27 Review

  • Clear, detailed audio
  • Great build quality and comfort
  • Detachable MMCX cable
  • Tight bass performance
  • Metal carrying case

  • The midrange is a little thin
  • Limited eartips included

Package and Accessories

This unboxing experience begins with something different from the norm. The H27 box is cylindrical in shape with a red and white colour scheme. Inside, the earphones are seated in a foam insert. Below the foam is a round metal carrying case which contains the cable and accessories. Here’s what you get in the box:

  • Shuoer H27 earphones
  • Metal carrying case
  • Detachable MMCX 8core Litz Cable
  • 3 pairs of silicone eartips

I love this carrying case and the cable is definitely above average in quality. However, I’d really like to see a larger selection of eartips provided. The included ones are good but it would be nice to see some larger ones and some foam tips included.

Build Quality and Design

The H27 shells are made from a 5-axis CNC crafted aluminium alloy with an anodized navy blue finish. Despite the teardrop shape, the build quality is nothing to cry about. In fact, the earphones feel premium and very robust.

Shuoer has opted for an inconspicuous and mature design with a smooth ridge pattern on the faceplates being the only visual embellishment. There is a single vent near the base of the metal nozzle. Internally, the H27 contains a single dynamic driver plus 2 Knowles TWFK-31736 balanced armature drivers.

Comfort and Noise Isolation

I found the H27 to be very comfortable earphones. They have a smooth finish and rounded edges all over. They’re lightweight and fit naturally in the ear cavity and are good for long listening sessions. With their low profile, these are also ideal for laying down. Noise isolation is above average, making the H27 ideal for commuting and noisy environments.

Provided with the H27 is a very nice detachable MMCX 8core Litz cable. It’s silky smooth and handles really well. Additionally, it has almost zero cable noise (microphonics). Colour-coded aluminium MMCX connector housings adorn the cable’s top.

There are some supple pre-formed ear guides that are very comfortable, even when wearing glasses. A small transparent chin slider sits above the aluminium Y-split. The cable terminates in a right-angled 3.5mm plug.

Gear used for testing includes the Shanling M5s and FiiO M5 as portable sources. On the desktop, I used my Windows 10 PC with Foobar2000 and the Singxer SDA-2. The H27 is easy to drive and doesn’t require a powerful source or extra amplification but the bass responds well to a beefier source.

Spring Cleaning

Clean and light are words that come to mind when I think of the H27’s sound signature. It has a fairly balanced presentation with upper midrange emphasis. Tight, reserved bass, clear and detailed mids plus crisp treble are the mainstays of this earphone. The overall tonality leans towards bright with an emphasis on detail, although it also has excellent bass extension.

Radiohead’s “You” is a track where the bass is fairly light in the mix and even more so when listening with the H27. The bass sits behind the vocals and upper midrange, bringing the vocals and electric guitars to the forefront. The vocals have more articulation and clarity than richness as a result of the reserved mid and upper bass which doesn’t lend much warmth to the lower midrange.

Where the H27 bass differs from most others is in its sub-bass presence. Rather than falling off below 60Hz, the H27 grows more assertive and is able to deliver a gratifying sub-bass rumble. But it’s a fast rumble that is highly controlled and moderate in quantity.


The midrange becomes the focus of the H27’s presentation, in particular, the upper midrange. Vocals and instrument size is fairly small, which results in a clean sound and good instrument separation. The upper mids can be a little aggressive at times, most notably at a higher volume.

It’s on tracks like Leech’s “The Man With The Hammer” where the H27 really shines. The guitars have an abundance of texture and pluck and the lean notes and lightness of the midrange make the soundstage feel expansive. Midrange instruments sit just in front of the treble, making this earphone a solid choice for acoustic and instrumental music.


Sitting just behind the midrange, H27’s treble has a surprisingly good timbre. It’s smooth due to its note thickness and fairly linear nature. A small peak around 7-8kHz adds some brightness and the occasional hint of sibilance.

Although it’s fairly neutral in quantity, the treble provides plenty of detail and sparkle. Additionally, its extension imbues an airiness that further enhances the stage with its openness. It’s a treble that is well suited to the lighter bass and enhanced upper midrange.


The H27 has a sound signature that’s synonymous with a larger soundstage and that proves to be the case here. It’s slightly wider and deeper than average with fairly even proportions. The strong sub-bass extension adds depth and centres the image plus the cleanliness and lean notes in the midrange give it excellent separation and imaging.

Tipsy Dunmer ($119)

H27 vs Dunmer
H27 (blue) vs Tipsy Dunmer (grey)

The Tipsy Dunmer (review here) is a single dynamic earphone with a similar form factor to the H27. After listening to the Shuoer, the Dunmer sounds much warmer with some signs of mid-bass bloat. Its midrange is richer and coloured compared to the cooler, thinner mids of the H27.

The Dunmer is also more upfront in its presentation, creating a more intimate soundstage but one with a more natural tone. It almost sounds as though the H27 is in a large room with a tiled floor and the Dunmer is in a smaller room with carpet. One is more clinical and precise while the other is more inviting and cosy.

Treble is more laidback and positioned further back than it is on the H27. Due to its fuller bass and thicker midrange, the Dunmer’s stage is less expansive than the H27 and vocals have a more forward positioning. They feel more lifelike and tangible on the Dunmer.

Physically, the shells of both IEMs have a very similar shape. The most obvious difference is in the materials used; the Dunmer has acrylic shells and the H27’s are aluminium alloy. Both earphones come with a gorgeous cable too. To sum up, the Dunmer would suit those who prefer a richer, warmer, musical presentation and the H27 is better for people looking for a more detailed, analytical sound.

TFZ No.3 ($109)

H27 vs No.3
H27 (blue) vs TFZ No.3 (grey)

The TFZ No.3 (review here) is a single dynamic driver IEM. No.3 has a wow factor, coming from its massive, punchy bass and lively treble. Its stage positioning is more upfront than the H27, as well as more intimate in dimensions.

In terms of bass, the No.3 has a similar curve that focuses the emphasis on its sub-bass. Where they differ most in the bass is in the No.3’s sheer quantity compared to the more neutral H27. The No.3’s more forward bass lends more warmth to its tonality while still maintaining a very clean midrange with exceptional clarity.

Both IEMs are comparable in the lower treble except, again the No.3 is more upfront. Its upper treble extension isn’t as good as the Shuoer and as a result, it has less openness and air. The No.3 has smaller stage dimensions but more precise imaging.

To summarize, the TFZ No.3 is an aggressive, fun-sounding IEM with exceptional clarity and powerful bass. The H27, on the other hand, is more analytical and mature and has a larger, airier soundstage.

If a cleaner and more precise sound is what you’re after, the Shuoer H27 is here to deliver. It’s a tuning that should also please those averse to an enhanced mid-bass as it is quite neutral in that aspect. The slightly cooler tone gives the H27 a mature tuning and more expansive soundstage. Aside from the audio, these earphones offer outstanding build quality and a gorgeous stock cable.
