About the Audio-Technica ATH-A990Z

The Audio-Technica ATH-A990Z headphones feature massive 53mm drivers. They produce a larger soundstage than you might expect from a set of closed-backs. Within that super-sized soundstage you'll enjoy fine-tuned imaging — instruments and vocals with a sense of place. These headphones reproduce sound accurately across a wide frequency range. And I'm a fan of Audio-Technica's 3D wing system headband (even though I've heard it's not everyone's cup of tea). I find the headband doesn't require a lot of adjusting, and it almost feels like the headphones are floating on your head.

Product Research


Overview: The ATH-A990Z is part of the Art Monitor-series of Audio-Technica's high fidelity headphones. These over-ear headphones have large drivers that are tuned to accurately reproduce extreme low and high frequencies, including Hi-Res Audio reproduction. They have an attached 10' cloth-wrapped cable with a 3.5mm plug and a 3.5mm-to-1/4" adapter. The A990Z headphones are ideal for studio and live work, or personal listening.

Drivers: The large 53mm large-aperture drivers feature bobbin-wound voice coils with oxygen-free copper wire (OFC) for superior performance and wide frequency response. The drivers are installed in lightweight aluminum housings, which reduce unwanted resonance. The top-mounted PCB provides excellent transient response, and improved airflow and precise diaphragm movement, while the Double Air Damping system (DADS) augments the deep bass.

Comfort Features: The headphones feature Audio-Technica's proprietary 3D wing support system, which provides an improved fit and greater comfort for long listening sessions. The closed-back design helps keep out unwanted ambient noise, while the premium, soft earpads gently surround your ear to provide the proper seal.

Cable: The ATH-A990Z has a 10' attached cloth-wrapped cable that is tangle-resistant and dampens contact noise into the headphones. The cable terminates into a sturdy gold-plated 3.5mm plug with a screw-on 1/4" (6.3mm) adapter, so you can listen to your smartphone, tablet, and portable devices, as well as studio mixers, sound boards, and home audio components.
