About this item
- Harman FR Professional Calibration: KZ Castor headphones adopt the Harman FR curve, a world-renowned acoustic reference in the Hi-Fi community. This technology faithfully reproduces the ideal balance between deep bass, natural midrange and detailed treble, delivering superior sound accuracy than most in-ear headphones on the market. Perfect for music analysis and studio monitoring.
- Smart Bass Boost: The KZ Castor headset is available in two versions. Enhanced bass version: Designed for audiophiles looking for deeper bass, it is based on the Harman FR curve, which improves sensitivity and low frequency dynamics for an unstoppable bass experience. Meanwhile, the mid and high frequencies are perfectly aligned with the Harman FR curve for an exceptional and superb bass experience.
- Tuned Sound: These headphones feature an innovative architecture with two superimposed dynamic speakers: 10mm bimagnetic dynamic speaker, 8mm dynamic speaker. In addition, the KZ in-ear headphones feature a professional acoustic filter to customize bass (2 levels) and treble (2 levels). You can create 16 different audio profiles to suit your favorite music style.
- High precision ergonomics: Made by 0.01 mm injection moulding (10x more accurate than 3D printing), the headphone case fits perfectly to the ear canal. Combined with our hypoallergenic medical silicone ear tips (3 sizes included), it ensures prolonged comfort and optimal sound insulation up to 26dB.
- Construction Pro Audiophile: Wired headphones with 1.2 m OFC anti-winding cable (3.5 mm jack), resistant to 10,000 bends. Internal double acoustic chamber structure dissociates bass/mid to avoid interference, with PET+PU composite membrane reinforcing sound dynamics.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
