## Long description

Koss PRO4AA wired supra-aural headphones provide monitoring-grade sound for stage and studio applications. Designed for use during rehearsals, live performances and recording sessions, these headphones feature a wide frequency response from 10 to 25,000 Hz that captures low-end depth and high-frequency detail. The supra-aural ear coupling and beige/black finish combine a compact profile with a neutral appearance, while the 3 m cable offers extended reach for performers and engineers working across a stage or studio space.
Advantages
The Koss PRO4AA delivers broad frequency coverage and consistent response suited to monitoring tasks. The wired connection preserves signal integrity for critical listening. The supra-aural design keeps the headphones relatively lightweight and easy to position, and the 3 m cable reduces the need for adapters or extensions in most rehearsal and stage setups. The two-tone colour option allows matching with different equipment and apparel.

How to use
Connect the headphones to a headphone output of a mixing console, audio interface or amplifier using the provided cable. Position the supra-aural pads so they sit comfortably on the ears, ensuring a stable fit for accurate monitoring. For stage use, route the cable to avoid tangling or interference with instrument movement. For studio use, confirm gain staging on the source device to avoid clipping or excessive levels while maintaining proper monitoring volume.
Usage recommendations
Use the 3 m cable to position yourself at a comfortable distance from the console or amplifier; avoid high-volume listening for extended periods to prevent hearing fatigue. For live situations, secure the cable to clothing or stage gear to reduce accidental disconnection or microphonic noise. Store the headphones in a dry place when not in use to preserve pads and cable integrity.
