Kiwi Ears Launches the Étude IEMs for Bassheads

Kiwi Ears Étude features the all-new Kiwi Vibration Transducer (KVT), a unique driver system that provides physical low-mid tactile vibrations, setting it apart from traditional bone conduction designs. Paired with a powerful 10 mm Beryllium-plated dynamic driver and three custom-tuned balanced armatures, the Étude achieves a stunningly immersive and detailed sound. With its precise 8dB sub-bass response, flat midrange, and extended treble, the Étude balances richness and clarity, offering a dynamic and lifelike listening experience.

KVT: Kiwi Vibration Transducer

The Kiwi Ears Étude is developed to showcase the KVT (Kiwi Vibration Transducer). Unlike traditional bone conduction drivers used in earphones, the KVT is more akin to scaled-down miniature vibration drivers found in Bluetooth vibration speakers. Featuring strong N52 neodymium magnets suspended by a heavy-tension spring system, the KVT physically vibrates a conduction plate when actuated by electrical currents. This technology provides tactile vibrations that enhance low-mid acoustics, offering a unique auditory experience.

Beryllium Diaphragm Subwoofer
A 10 mm Beryllium-electroplated diaphragm driver is utilized for the bass. Engineered to serve as a subwoofer, the dynamic driver dishes out incredibly precise and fast kick drum hits and rich bass guitar notes. Paired with the KVT, the lows deliver deep rumble and a 3D-like imaging.

Custom Balanced Armature Drivers

The Étude features custom-engineered balanced armature drivers developed by Kiwi Ears. A high-efficiency midrange driver delivers clean, robust fundamentals for vocals and instruments, while a dual ultra-high frequency tweeter enhances microdetails and atmospheric nuances. This configuration ensures a seamless and natural transition across the entire frequency spectrum.

Precision Tuning

The Étude is meticulously engineered to meet Kiwi Ears’ standards for tonal balance. Sub-bass is elevated to 8dB, delivering impactful yet controlled low-end that maintains a refined equilibrium between richness and clarity. The midrange remains flat and neutral, anchored by a 250 Hz bass shelf crossover that preserves vocal and instrumental accuracy without coloration. Treble frequencies are acoustically tuned for a smooth, resonant presentation, completing the Étude’s cohesive and natural tonal profile.
