About Kiwi Ears
Precision Planar Magnetic Driver for Lifelike Sound
Featuring a custom 57.5mm x 51mm closed planar magnetic driver, the Kiwi Ears x Z Reviews: Serene delivers lightning-fast response, accurate bass, and high-resolution clarity across the frequency range.
More Information...Unlike conventional dynamic drivers, the fully enclosed planar driver in the Serene is engineered to eliminate rear wave reflections with a proprietary refractory filter. This design provides natural tonality, deep controlled bass, and crystal-clear highs. Fast transients ensure every note is reproduced with lifelike speed and detail, creating an engaging and immersive listening experience.

Comfort Built for Endless Listening
Lightweight polymer cups, aluminum framing, and plush vegan leather padding make the Serene exceptionally comfortable for long sessions.
More Information...The Serene’s ergonomic design includes a padded headband and soft earcups lined with vegan leather, offering balanced clamping force for all-day wear. Its dual-pivot joints adapt to your head shape, while spring steel allows clamp adjustment for a personalized fit. At under typical category weight, the Serene provides fatigue-free comfort during commutes, gaming, or extended studio sessions.

Advanced Noise Isolation with Natural Tonality
Custom memory foam pads and a proprietary driver filter minimize unwanted reflections, providing effective passive isolation without sacrificing openness.
More Information...The Serene’s closed-back design is enhanced by custom-tuned memory foam pads wrapped in soft vegan leather. Combined with its unique refractory filter, this prevents internal sound diffraction while blocking external noise. The result is a quiet listening space with clean, undistorted sound, retaining an airy and natural presentation ideal for both private and professional use.

Cable Customization for Tailored Sound
Standard dual 3.5mm connectors and a detachable cable design let you upgrade or tune the Serene’s sound to your preference.
More Information...The Serene comes with a detachable cable using dual 3.5mm inputs, making it compatible with a wide range of aftermarket cables. Its sensitive planar drivers are responsive to impedance changes, allowing subtle tuning through cable swaps. This flexibility gives you the freedom to optimize your listening experience, whether for casual music enjoyment or professional monitoring.

Modern Aesthetic with Retro Inspiration
