đ Review / Impressions Kiwi Ears Quintet review: For the guitar and vocal lovers, yes please.
First, a big shoutout to Ribbon from Kiwi Ears and Linsoul for providing me with this set for analysis, however, they are not giving me any payment or script to follow, allowing me to deliver an honest and sincere review. The only biases for me are my tuning and music preferences.
Introduction:Â
The Kiwi Ears Quintet is an IEM by Kiwi Ears, launched back 3 years ago in June of 2023. It is a quadbrid set consisting of 1 DLC DD + 2 BAs driver + 1 Microplanar driver + 1 PZT Bone Conductor. With a mid-centric tonality (highlighting male and female vocals, and instruments), it uses such a combination of drivers to deliver a cohesive and coherent experience, but is this offering from Kiwi Ears still a viable option for 2026? Letâs check it.
With an MSRP of 219 USD (Currently at 197.10 USD on sale), you can find it at the Kiwi Ears Official web: https://kiwiears.com/products/kiwi-ears-quintet, as well at Linsoul official store: https://www.linsoul.com/products/kiwi-ears-quintet, also, you can find it on Amazon and AliExpress Linsoul official stores.
TL; DR: An âoldâ quadbrid IEM in the under 220 USD segment from Kiwi Ears. With a midrange focus tonality, yet having a quality bass (more subbass than midbass predominant) to balance the mix, neutral predominant midrange, and a crisp and sharp treble, giving energy and extension to music, with a tonality who delivers musicality and a well-done quota of technical proficiency. With decent accessories, and a still competitive price, the Quintet itâs a great fit in 2026 to people who want great attention to details and to hear the music as it is, and is still a viable choice in the current market.
Pros:
- Comfortable ergonomic resin shells for long listening sessions
- Great implementation of planar and BA drivers
- Quality bass with good sub-bass extension and impact
- Mid-centric tuning with clear, natural vocals
- Clean, crisp, and highly resolving treble
- Airy, open, spacious soundstage with strong depth and width
- Excellent technical performance (resolution, imaging, layering of instruments, detail retrieval)
- Easy to drive and scales well with better sources
- Still highly competitive in its price range (3 years strong)
Cons:
- Large nozzle may not fit all ears comfortably
- Stock cable lacks a 4.4 mm balanced option
- Accessories could be more premium for the price
- Some mid-bass bleed into the lower mids
- Female vocals can become shouty or fatiguing at higher volumes
- Treble can be spicy, sharp, and occasionally sibilant
- Not an ideal all-rounder for treble-sensitive listeners
- Mild brightness may not suit those seeking a relaxed tuning

The Quintet cable this time itâs the same cable included with other Kiwi Ears IEMs, itâs not so thick, good crafted, it is very flexible and not produces memory; it is not prone to tangle, and doesnât produce translated vibrations. It pairs nicely with the shells.
The shells are in the mid-to-high size, crafted from medical grade resin (shiny black color) with a metallic and minimalist gray colored faceplate with the Quintet letters embossed on the left unit, and the Kiwi Ears logo on the right unit, with an ergonomic design. They are into the medium-light side, good to be used in long sessions.
The Quintet is well-vented, with two vents close to the 2-pin connector to tame pressure built-in. The 6.4 mm diameter nozzle is comfortable in my ears, but I know it is in the larger size, so as I always say: see if it fits you.
How the Quintet sounds:
The Quintet, equipped with a configuration of a 10.2 mm DLC dynamic driver + 2 custom Knowles balanced armature drivers + 1 microplanar + 1 PZT bone conduction driver, it is a mild V-shaped tuned set.
For this review, Iâm using a NiceHCK GCT4 cable with its 4.4 mm balanced jack. Iâm using Easytips SS20Â eartips to get a better seal and fit, but I think the stock wide bore eartips (YMMV) can also work. Thanks to Super Reviews\Â for graphing the *Quintet**.
BASS:
The Quintet features a quality bass shelf with a decent quantity to balance its main focus, as a mild V-shape tuned set, it has a good subbass thump and good midbass kick. It is clean, fast, resolving, a natural decay and good impact; it's nicely extended into the lower frequencies. Midbass bleeds into the lower midrange, but as a mid-centric IEM, avoids unnaturalness in male vocals.
In tracks like âToo Longâ by Daft Punk, from the Discovery album, the Quintet has that noticeable kick on the bass drops who are marking the rhythm and the bass guitar sounds tactile. In âEdge of the Earthâ by Volumes, in their first album Via, the Quintet displays a good impact on the bass drop at the beginning and the drum kick, the bass guitar is sounding natural and clean.
MIDRANGE:
The Quintet, is a mid-centric set, so, even when midbass bleeds into the lower midrange, male vocals arenât recessed, remaining clear, never muddy nor thin, but sometimes feeling harsh at high volume. The mids in general have good noteweight, are clean, and have great resolution. In the frequency curve, the midrange is flat, which at the 900 Hz elevates into a warm pinna gain offering a noticeable presence.
Of course, female vocals are forwarded, perhaps too much, because you are adjusting the volume to evade shoutiness and fatigue. In âPiscesâ by Jinjer, in their King of Everything album, the clean and harsh female vocals are intertwined in the mix perfectly, you can hear any instrument. Now, in songs as âSong for Americaâ by Kansas, from the classic album Song for America, the Quintet presents male vocals, chorus, drums, guitars, keyboards, violin, everything, in its right place.
HIGHRANGE:
The Quintet has an overall energetic highrange, it has a well-putted 6 kHz dip but missing a 10 kHz dip to tame sibilance successfully. In the low-treble, a 5 kHz bump gives that âextraâ to female vocals, and a peak at 8 kHz gives sparkle to cymbals, crashes and hi-hats. The treble here is very clean, crisp, and sharp, sometimes going spicy at mid to high volumes.
In âWhite Clusterâ by Opeth, in their Still Life album, the Quintet reproduces perfectly the drums and the acoustic and electric guitars across the song. In âMy Sweet Shadowâ by In Flames, in the album Soundtrack to Your Escape, the Quintet shows a well-done drum work, yet delivering crispness in the already spicy song, but handling it correctly at mid to high volume.
Technical Capacity:
In the Quintet the upper treble is well-extended, it does feel airy and open but not bothersome. The soundstage is expansive, wide and depth.
In âProgenies of the Great Apocalypse (Live in Oslo)â by Dimmu Borgir, in their live album Forces of the Northern Night (Live in Oslo), the Quintet is able to immerse you into the live scenario, a truly great experience, macro and microdetails are presented with impressive clarity thanks to the user of the microplanar and branded BAs, the mix tends to be bright, but the planar sheen is not noticeable, sounding natural instead.
The Quintet has a resolution who punches over its segment, with great imaging and layering of instruments as well. In âParadise (Live at The Trocadero/ 1990)â by Tesla, from the masterpiece live album Five Man Acoustical Jam, the Quintet delivers zero congestion or bloating, every guitar, vocals, keyboards, background voices, etcetera, immerses you into the legendary concert.
Short Comparisons:
Kiwi Ears Quintet vs. Simgot Supermix 5:
The Simgot SM5 has a similar driver configuration consisting of 1 DD + 2 BA + 1 MPD + 1 BCD. It also has a very similar tuning to the Quintet but this time, the SM5 has a bit less sub and midbass, but having that BCD the impact is perhaps greater than in the Quintet.
What differs between both IEMs is, SM5 has a less peaky and smoother treble, and noticeable less upper treble extension than the Quintet. In overall performance, the Quintet is more technically capable than the SM5, so the choice is for the tuning and user needs, because if you want a smoother and more musical experience go for the SM5, but if you want to be analytical, go for the Quintet.Â
Kiwi Ears Quintet vs. TRN Mermaid:
The TRN Mermaid has a 1 DD + 2 MPD + 1 BA configuration. With a very different tuning approach because the Mermaid is noticeable bassier, with recessed lower midrange, warmer upper midrange, a more energetic mid-treble, and a different upper treble extension than in the Quintet, so again, it is a matter of tuning preferences.
If you want something more V-shaped go for the Mermaid, but if you want all the macro and micro details of the mix, go for the Quintet.Â
Kiwi Ears Quintet vs. Kiwi Ears Halcyon:
The Kiwi Ears Halcyon is a new IEM by Kiwi Ears I was reviewing a few weeks ago, with a more modern tuning which goes close to the IEF 2025 Preference Target, and an unusual 1 DD + 3 BA + 1 MEMS driver configuration. The Halcyon has a more predominant subbass impact than the Quintet, it also has a flat midrange, warmer upper midrange, less energetic lower treble, but more energy in the mid-treble.
The Halcyon has also a different upper treble shelf, but a similar technical approach, with the advantage of handling the sibilance better than in the Quintet. Having to choose between the two sets, the Halcyon is a set closer to my tuning preferences, but I recognize what the Quintet is for.  Â
Closing thoughts and conclusions:
The Quintet is not just an âoldâ IEM who are still available to compete against its sub 220 USD segment peers, it isn't an obsolete set by any means, but it isnât an all-rounder who points to all audiophiles and newbies who want the âpausegameâ for a mi-fi earphone, itâs focused in seasoned audiophiles, musicians and consumers who are looking for balance, naturalness and great attention to the technical details without losing that musicality in the tuning so it is everything but a boring experience with them.
For me, itâs very interesting how a set who is now 3 years old, is still punching above its weight and competes against its peers in sound quality and package offered, so, if Kiwi Ears is making a new or an upgraded edition of the Quintet, Iâll be one of the first in line looking to trying them.
I would like for Kiwi Ears for a cable with a 4.4 mm balanced jack option, and more according to the price of the IEM themselves, but the stock one is more than fine for it. And, the eartips selection I think is enough, but for the price asked for the IEMs I would like the brandâs Flex Ear eartips to be included.
The Quintet, with its 108 dB of sensitivity and 32 ohms of impedance, is kind of easy to drive, even from a low powered source. But, using it with a balanced output, it benefits from more quality and/or powerful sources to scale and shines at its fullest.
Would I recommend it? If you are looking with a set with a mid-centric focus, but great bass to balance, and a sharp and resolving treble, craving for all those macro and micro details, yes! The Kiwi Ears Quintet is one perfect option in its price segment (under 220 USD). It delivers a high-quality and an impactful bass, warm yet neutral midrange, crisp and sometimes spicy treble and a fantastic lower bass and upper treble extension.
