The Koss QZ99 Around-Ear Noise Isolating Headphones are a closed-back, over-ear audio solution designed for focused listening. Featuring dynamic drivers and a comfortable headband, these black headphones offer both mono and stereo sound fields through a gold-plated 1/8" / 3.5 mm TRS connector on an 8-foot non-detachable cable. With a 60 Ohm impedance, they are ideal for use with a variety of computing and electronic devices where clear, isolated audio is desired.
Choose between open-back (spacious sound, leaks noise) and closed-back (isolating, punchy bass) designs based on your environment. For wireless headphones, prioritize comfort and Active Noise Cancellation (ANC) performance. Available from $64.99.
Wired headphones have no ongoing costs besides occasional earpad replacements. Wireless headphones function as consumables, as their batteries will eventually degrade after a few years of daily use.
