Kiwi Ears Quintet

1DD + 2BA + 1 Planar + 1 PZT In-Ear Monitor
Regular price $219.00 USD
Sale price $219.00 USD Regular price

The Kiwi Ears Quintet utilizes 4 driver types, including a DLC dynamic driver, 2 balanced armature drivers, a planar magnetic driver, and a piezoelectric bone conductor, delivering high-resolution audio.

The new planar tweeter system in the Quintet, called MPT (Micro Planar Transducers), offers low noise, high output, and crisp treble, enhancing audio resolution and texture.

Kiwi Ears developed the MPT driver to address the challenge of achieving high-quality ultra-treble, providing sustained frequencies from 4kHz to 40kHz with natural tonal texture and integration.

The Quintet offers a balanced tonal signature, combining the best qualities of each driver type for impactful bass, neutral upper mids, detailed treble, and an extended soundstage.

4 Driver Types, 5 Drivers per Side

The Kiwi Ears Quintet utilizes 4 different types of drivers, consisting of 1 Diamond-Like Carbon (DLC) dynamic driver, 2 balanced armature (BA) drivers, 1 planar magnetic driver, and 1 piezoelectric (PZT) bone conductor. With a total of 5 drivers per each ear, the Quintet delivers extremely high-resolution audio comparable to professional studio monitors. A large 10mm DLC driver was selected as the sub-woofer due to DLC’s high responsiveness and tensile strength, which pumps out impactful bass slams, but with fast decay speeds. 2 Knowles balanced armature drivers deliver natural and resolving mids, a classic example of why balanced armatures are beloved in the industry.

We are excited to announce the utilization of a new planar tweeter system in the Quintet. The MPT (Micro Planar Transducers) is a new driver technology for the IEM industry. These new tweeters feature the classic planar magnetic driver circuitry but with a smaller footprint for use in hybrid designs. With an extremely low noise floor and high output capacity, these planar magnetic drivers deliver crisp and detailed treble that is unique from typical BA or EST (electrostatic) tweeters used in most IEM’s today. Finally, a piezoelectric driver was utilized to deliver ultra-treble microdetail and air. In R&D testing, the presence of the PZT driver significantly enhanced perceived audio resolution, texture, and sound stage, making it a no-brainer to be an addition in the Quintet.

Kiwi Ears Micro Planar Transducers (MPT) Drivers

Achieving a high quality ultra-treble has been a challenge in the IEM industry. BA drivers are compact, but offer low ultra-treble extension, and are also limited by their output and timbre quality. EST drivers are difficult to utilize in multi-driver setups as they have very low output, often being masked by other drivers’ volumes. Additionally,  EST drivers can sound very metallic at high voltage, resulting in an unnatural presence. For this reason, Kiwi Ears has developed a new ultra-treble tweeter with a small modular size of only 5mm, but a tremendous output of 118dB. The Kiwi Ears MPT driver is efficient at producing sustained treble frequencies from 4kHz to 40kHz.

Typical BA or EST drivers have diminishing treble output after 8kHz. However, the MPT driver can maintain the same constant sound pressure at 14kHz as at 4 or 8kHz. This allows extreme flexibility in tuning the MPT driver to match other driver types such as BA or DD, as their outputs are similar. Furthermore, the MPT driver has a significantly more natural tonal texture than EST or BA drivers, achieving better integration in the mix. 

Balanced Tonal Signature

A balanced sound signature is a core belief at Kiwi Ears. The Quintet took almost a year in development due to the engineering difficulty of combining all of its driver types. However, the result is a completely balanced tone that accurately reflects the best qualities of each driver. The sub-bass hits strong and fast, with a 9dB shelf that transitions into a flat mids at 300Hz. This mids-bass transition ensures that there is a slight warmth in the lower mids for bass guitar notes to be in the mix, but still retain a studio-monitor-like neutrality to the upper mids.

This creates a natural and clean tone without any muddying or bloating. The treble accurately peaks at 3kHz to match the acoustic perception of the human ear’s pinna, with a gradual decay into the upper treble. Thus, the treble is well-detailed and sparkles, but without any shrillness or harshness. The planar and PZT drivers provides a good extension into the treble until 40kHz, making a higher sense of resolution, airy atmosphere, and soundstage.

The best IEM I have

The best IEM I ever have!

William Day
Great IEMs!

I really enjoy these; they are a nice complement to my other IEMs. Also, they are vented, so the pressure doesn't build up after extended listening. Awesome IEMs, just make sure to get a good seal. Try out different tips, to discover the best seal, and you will enjoy these.

Scott Hume
A plain looking gem that sparkles

A beautiful engaging IEM but quite tip dependent. Sounded the best with Moondrop spring tips. Love em!

Best set in my collection

It's my best and most expensive set yet. In my collection, there is one set that can compete somewhat in the details department, but is less fun. It's Thruethear Hexa. It's less bassy than Kiwi ears, but as detailed, to my ears.
S12 that I have is a set that always left me with mixed feelings, but it's closest in price within my collection. It definitely sounds less natural, than Quintet.
Quintet is a lovely set. Detailed yet still very musical. It gives lots of fun, but it's not boomy or muffled. It sounds very natural. Definite recommendation!

Daniel Kusk
Amazing iem but terrible fit for me

The sound quality per price is the best that I have heard but I couldn’t get a good fit, nozzle is too long and just uncomfortable in the ear for me

These are an amazing experience, Quadbrid sub $500!!

Build Quality: The body of the IEMs is superb, the 3D-printed resin and faceplate have a smooth texture creating a high-end feel to the touch. The included cable never kinks or gets tangled, this makes using them and the cable effortless and frustration-free. The tips offer different music experiences and thank you for so many size options.

Sound Quality: These were able to play almost everything at an exceptional level at their price point! Instrumental music like Claire de Lune, Fur Elise, The Four Seasons e largo pianissimo e Sempre performed well with good tonality and accuracy, Pachelbel: Canon in D Major performed by Sir Neville Marriner was a treat! Orchestral and Opera style music like Requiem in D Minor, K. 626 Sequence VI, Lacrimosa dies illa, Erlkonig Op 1, D. 328 were quite the experience!! Popular/Modern music played well. They shined in music with strong vocals, Blake Shelton, Adele, Nicotine Dolls, Bob Segar, etc. On the flip side, I didn't see this much but songs with bad mixing or some of the Baroque, Classic, Orchestral style music with floor noise did not play or sound well. They weren't bad experiences, but the Quintets identified those areas and it was hard to ignore. One experience that sticks out is Ellie Goulding's Explosions. Maybe it is the Piezoelectric Bone Conductor creating that higher end, but the mix of that song came off shrill in some areas, not brooding and dark as it typically would. 

But I highly recommend these at this price point, with that Quadbrid setup, it's hard to pass up such a value and experience!! Great job on these Linsoul! YouTube video placeholder
Believe the Hype

I really love the Quintet!

KIWI EARS QUINTET: Cheap, Affordable Quadbrid Set

Quadbrid driver implementation on an IEM can only be on TOTL range. And it is quite fascinating to see such a multi-driver set-up on a US$200/£161 price range. Will the Kiwi Ears Quintet simply become a game changer in the current IEM game?


△ Solid yet lightweight shell chassis, good colour contrast between its cavity base and face plate.
△ Inclusion of a good quality stock cable.
△ Sufficient amount of ear tips to choose from.
△ IEM storage case for carrying and decent protection for the IEMs.
△ Mild U-shaped, almost neutral sound signature for neutralheads.
△ Precise and punchy bass response.
△ Clear, transparent and neutral midrange.
△ Remarkable tonal colour presentation on female vocals and instruments especially strings and woodwinds
△ Bright, crisp and airy treble response.
△ Wide and tall perceived sound/speaker stage to have a good spacious headroom.
△ Remarkable imaging projection with good separation capabilities.


▽ Definitely not for bassheads.
▽ Bass tones seems to have that lack of depth and less darker pitch.
▽ Male vocals particularly on baritone-type doesn't have an enough note volume to have a warm and lusher sound from them.
▽ Instances of sibilance on a sibilant-laden tracks.
▽ Quite a paucity on its sound/speaker stage's depth.

Kiwi Ears Quintet.

Incredible, more comfortable for me than the Moondrop Kato. No fatigue using for many hours. I also have the LETSHUOER x Z12’s which I am also pretty delighted with. The Quintet is probably a step up!
