TL;DR The Kiwi Ears Étude in-ear monitor (IEM) introduces Kiwi Vibration Transducer (KVT) tech for tactile low-end immersion.
The IEMs combine 10mm beryllium-plated dynamic drivers with three balanced armatures.
The Étude are on sale now for $119 at Amazon, Linsoul, and other retailers.
Kiwi Ears recently unveiled the Étude, a pair of high-end in-ear monitors (IEMs) that the brand promises can deliver exceptional bass response via the brand’s all-new Kiwi Vibration Transducer (KVT) technology. Unlike conventional bone conduction tech, KVT introduces a scaled-down tactile vibration system akin to what’s found in Bluetooth vibration speakers, which Kiwi Ears promises will bring a physical edge to low-mid audio reproduction.
The Étude are powered by 10mm beryllium-electroplated dynamic drivers, engineered to act like subwoofers. The driver aims to deliver crisp, fast kick drums and lush bass guitar tones. Paired with the KVT’s vibration-enhanced plate system — driven by suspended N52 neodymium magnets — the result is what Kiwi Ears describes as a deep, rumbling low-end with 3D-like imaging.

The Étude also house three custom-balanced armature drivers: a dedicated midrange driver tuned for vocal and instrumental clarity, and a dual ultra-high frequency tweeter to enhance microdetails and ambient textures. A flat midrange and carefully extended treble round out the tuning, with Kiwi Ears aiming for a lifelike, neutral profile.
Kiwi also says the Étude are tuned with an 8dB sub-bass lift, grounded by a 250Hz crossover shelf to preserve vocal presence without adding coloration. It hopes this will bridge tactile impact with high-fidelity detail.
