PRO4AAT Stereo Headphones

The PRO4AA Titanium features dynamic elements for an exceptionally wide frequency response. A 2 mm titanium coating on its diaphragms increases the rigidity of the element, ensuring exceedingly accurate sound reproduction. One-inch (25.4 mm) diameter oxygen-free copper voice coils improve signal transmission and conduction for cleaner, clearer sound. Closed Pneumalite cushions form a positive, comfortable seal around the ears, maximising bass frequencies and isolating the listener from ambient noise.

Designed for frequent use over extended periods, the PRO4AAT's durable steel and rubber headband is generously padded. Adjustable slide bars ensure a snug fit, also critical for hearing every note and keeping unwanted sounds out. The heavy-duty coiled cord affords ample flexibility of movement. A 3.5mm (1/8") plug and a 6.3mm (¼") adapter, both with gold-flashing, are included.

Whether you are a sound professional or simply love music, the PRO4AAT will deliver excellent isolation, accurate sound reproduction, and the excitement of a live performance to your recording. Built to last, the PRO4AAT is covered under Koss' Limited Lifetime Warranty - the only warranty of its kind in the stereophone industry.

Avoid using headphones with the volume turned up for an extended period of time. Doing so can damage your hearing. It is advisable to keep the volume at a moderate level at all times. For your own safety, please do not use when driving or cycling.
