Meet the KZ Castor Pro 2: an in-ear monitor that combines a 10mm planar magnetic driver and a 10mm dynamic driver per earpiece with four physical tuning switches. Choose your connection, microphone option, and finish to build a setup for your music.

Two Driver Technologies in One IEM

The Castor Pro 2 brings planar magnetic and dynamic driver technologies together in the same earpiece. Its dual-driver design pairs two different approaches to sound reproduction, making it a distinctive addition to the Castor family.

Adjust the Sound with Four Tuning Switches

Explore the earphones' tuning through four physical switches. These controls let you adjust the sound at the earpiece and find the setting you prefer for different tracks and listening sessions.

Ergonomic Shape, Detachable Cable

An ergonomic in-ear shell and over-ear cable layout keep the familiar IEM form. The detachable cable gives you flexibility to replace the cable or change your connection setup with a compatible accessory. Choose a Black or Silver finish.

Choose Your Wired Connection

Select the cable configuration that suits your device and how you listen:

• 3.5mm or USB-C: choose the connector that matches your audio source.
• Mic or No Mic: choose a wired cable with or without a microphone.
• Black or Silver: select your preferred finish.

Your selected variant determines the supplied cable and finish.
