QZ99 Around-Ear Noise Isolating Headphones

Product Description

The QZ99 headphones from Koss provide high-quality audio and exceptional noise isolation in a comfortable design. The headphones use neodymium drivers to provide detailed audio with a wide frequency response. A stereo/mono selector switch provides versatility, while a built-in volume control offers a convenient way to quickly adjust volume levels.

The padded, adjustable headband provides a secure and comfortable fit. The closed-back earcups and thick around-ear Pneumalite ear cushions provide long-lasting comfort and a high degree of noise isolation, allowing you to focus on your music instead of your environment. The single-sided coiled cable provides a variable amount of slack and is resistant to tangles. The gold-plated 3.5mm mini plug and included 1/4" adapter provide wide compatibility with a variety of consumer and professional electronic devices.
