Our Biggest Planar Driver Yet
The Aether features the largest IEM planar driver we've developed to date. Equipped with a 15.3mm diaphragm and powerful, multi-layered N52 neodymium magnets, this driver delivers a sound that mimics the experience of full-sized headphones. Compared to typical 12mm or 14mm planar drivers, the Aether's 15.3mm driver achieves greater output with lower distortion, dramatically enhancing audio quality.

Speaker-like Sound
Thanks to the larger driver, the Aether not only improves resolution but also provides a wider, more precise soundstage and better imaging. Our newly designed chamber and improved ventilation help create an open-back headphone or stereo system-like experience. The result is an airy, lifelike sound, characteristic of planar magnetic drivers.

Tonal Integrity
Tonal integrity was a key focus during the design of the Aether. Adhering to Kiwi Ears' signature tonal balance, the Aether offers a natural, accurate sound. The bass delivers deep, subwoofer-like punch, while a mild mid-bass to mids transition adds warmth to the sound's body. The midrange (300 to 800Hz) remains flat for monitor-like accuracy, ensuring true representation of instruments and vocals. The treble is finely tuned to align with the human ear's tonal perception, providing a clear yet natural high-frequency response.

A Sound for Professionals
The Aether's planar magnetic driver excels in speed, responsiveness, imaging, and soundstage. Combined with its balanced tonal signature, the Aether is perfect for professionals seeking precision in sound. It also caters to gamers and audiophiles who want a highly immersive and engaging listening experience.

Detachable Cable System
The Aether comes with a detachable 2-pin 0.78mm connector system. This modular design allows for easy cable swapping to accommodate different setups or preferences.
