KVT: Kiwi Vibration Transducer

The Kiwi Ears Étude was developed to showcase the KVT - Kiwi Vibration Transducer. Our in-house vibration transducer is not like bone conduction drivers currently used in earphones. Rather, it is more akin to scaled down miniature vibration drivers that are used in bluetooth vibration speakers. The KVT uses strong N52 neodymium magnets that are suspended by heavy-tension spring systems that physically vibrate a conduction plate upon actuation by electrical currents. The KVT provides physical tactile vibrations to relay the sound, enhancing low-mid acoustics.

Beryllium Diaphragm Subwoofers

A 10mm 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.

Precision Tuning

The Étude has been carefully engineered to meet Kiwi Ear’s standards for tonal balance. The sub-bass is powerful yet controlled at 8dB to provide the correct balance between richness and clarity. The midrange is flat and neutral, with a 250Hz bass shelf crossover, which allows vocals and instruments to sound accurate and without any coloring. The treble has been acoustically tuned to be comfortable and resonant, establishing the Étude’s tonal balance.

Custom Balanced Armature Drivers

The Étude utilizes Kiwi Ears’ custom in-house balanced armature drivers. A single high-efficiency midrange driver delivers robust and undistorted fundamental frequencies of vocals and instruments. A dual ultra-high frequency tweeter is utilized to bring out microdetails and air within the music. Paired together, the transitions throughout the entire frequency range is seamless and natural.
