Описание на продукта
The Koss Quiet Zone QZ PRO stereophone delivers a winning combination of passive and active noise reduction (ANR) for music lovers who are looking for a little peace and quiet on the go.
Designed with soft, vinyl closed cushions that create a seal around the ear, the QZ PRO creates a passive, mechanical seal that reduces ambient noise while retaining bass frequencies.
The QZ PRO affects those noises between 30Hz and 1400 Hz, allowing music and voice to come through loud and clear.
The QZ PRO operates on 2 "AAA" batteries and delivers approximately 30 hours of continuous play. Additional features include a 4-foot, single entry, straight cord and a 2-prong airline adapter.
To install the batteries: The QZ PRO does operate on batteries which are located in the right earcup. If you grasp the right ear cushion and turn counter clockwise, the ear cushion should twist off. The battery compartment is located inside.
Frequency Response: 40-20,000 Hz
Impedance: 32 ohms
Sensitivity: 90 dB SPL/1mW
Distortion:
