Professional Studio Headphones
The Koss PRO4AA over-ear headphones are built for critical listening in broadcast and recording environments. First released in 1970, they use dynamic elements to provide a wide frequency response with strong noise isolation. The tan finish and steel-reinforced headband give them a distinctive retro appearance.
Suited for fixed studio work; not for portable use
Audio engineers and broadcasters who need reliable isolation and a secure fit will appreciate the adjustable slide bars and padded rubber headband. The package includes microphone mount hardware for added versatility. Listeners who need a short straight cable or a smaller connector for mobile gear should consider other models.
6.3 mm quarter-inch plug
An 8-foot coiled cable terminates in a 6.3 mm (1/4") plug, matching professional audio interfaces and mixing consoles. The headphones weigh 1.85 kg, reflecting their durable steel construction. Verify that your equipment provides a matching quarter-inch jack before purchase.

Questions about this item
Does the 1.85 kg weight make the PRO4AA uncomfortable during all-day studio sessions?
The adjustable slide bars and generously padded rubber headband are designed to distribute the weight evenly for a snug, secure fit that reduces fatigue during extended use.
What audio source connections are required to use the 6.3 mm plug on the PRO4AA?
You need a device with a 6.3 mm (1/4-inch) headphone jack, such as a professional audio interface, mixer, or dedicated headphone amplifier, as no adapter is included.
Will the PRO4AA's 1970-era dynamic driver design work reliably with modern digital audio workstations?
Yes, the dynamic elements provide a wide frequency response suitable for accurate monitoring, and the 6.3 mm plug connects directly to contemporary professional audio interfaces.
