Kiwi Ears Quartet

Introducing the Kiwi Ears Quartet, designed to deliver a warm, bass-forward sound signature with versatile tuning options at an affordable price point of around 109 €~. With its hybrid driver setup, featuring 2 dynamic drivers and 2 custom balanced armature drivers, these IEMs provide a flexible and engaging listening experience.
Here's an overview:

Features & Build

Hybrid Driver Setup:
The combination of two dynamic drivers and two balanced armature drivers allows for a balanced sound, leaning toward a warm, bass-heavy profile.

Tuning Switches:
Each earbud comes with tuning switches, offering 4 different sound tuning options. The changes are subtle, mostly affecting the bass and treble ranges, allowing listeners to fine-tune their preferred sound.

Comfort:
The IEMs are quite comfortable and come with 3 different ear-tip sizes to ensure a good fit. However, the soft cable tends to tangle a little bit.

Audio Quality

Bass:
The Kiwi Ears Quartet shines in its bass performance, with a heavily bass-boosted, warm sound signature. The bass extends slightly into the mids but manages to avoid sounding overly muddy.

Midrange:
Despite the bass emphasis, the midrange remains fairly clean, and vocals aren’t overshadowed much, though the warmth is present.

Treble:
The treble is relaxed and non-aggressive, making these IEMs suitable for long listening sessions without fatigue. If you're used to brighter earphones, the treble won’t seem too piercing.

Soundstage & Imaging:
The soundstage is not very spacious but remains natural and accurate. Imaging is decent for an IEM at this price point and handles complex recordings reasonably well, making it a solid option for casual gaming and general listening.

Tuning The tuning switches provide slight adjustments, focusing mostly on the bass and treble. Whether you prefer a bass-heavy signature or something more balanced, the switches give you the flexibility to make those tweaks.

Soundstage: 
While the soundstage isn’t the most expansive, it manages to maintain clarity and accuracy in busy recordings. Gaming and casual listening should be enjoyable with the Quartet's sound signature.

Conclusion

The Kiwi Ears Quartet is an excellent choice for those seeking a fun, warm sound with plenty of bass and good tuning flexibility. While it may not be the most detailed or technical IEM, its relaxed, engaging signature makes it perfect for casual listeners who want an enjoyable experience without harsh treble or overwhelming detail. The comfortable fit and solid build quality make it a great option for extended listening sessions.
