Koss KPH30 Wireless On-ear Headphones, Rhythm Beige/Stealth Grey

The KOSS KPH30 is a wireless on-ear headphone that utilizes Bluetooth 5.2 for connection to compatible devices. Its dynamic drivers are engineered to cover a wide frequency response range of 15 Hz to 25,000 Hz, with an impedance of 32 ohms. The system supports multiple audio codecs, including aptX, AAC, and SBC, which enables higher-fidelity audio streaming from sources that also support these standards. The closed-back, on-ear design contributes to passive noise isolation during listening sessions.

For extended use, the integrated Li-ion battery provides up to 20 hours of continuous playback and recharges in approximately two hours via the USB-C port. An integrated omni-directional microphone and on-board controls are included for managing calls and media playback without direct interaction with the source device. The headphones have a wireless operating range of up to 10 meters. For added versatility, an optional analog pass-through cable can be used for a direct, wired connection.
