Audio-Technica ATH-AD900X

Open-air headphones feature a perforated ear cup design that allows air to pass through, resulting in a more natural, spacious soundstage. Because they are not sealed, they do not block out external noise and will leak sound to those around you, making them best suited for quiet environments.

Yes, they are designed specifically for extended wear. The 3D Wing Support system automatically adjusts to your head shape to distribute weight, and the large, cushioned ear pads are built to minimize pressure on the ears.

With an impedance of 38 ohms and a sensitivity of 100 dB/mW, these headphones are relatively easy to drive. You can achieve good volume levels from most smartphones, laptops, or tablets, though a dedicated DAC or amplifier may help you extract the maximum dynamic range.

The 'CR' designation indicates these are certified refurbished units. They have been inspected and tested to meet the manufacturer's performance standards, offering the same audio quality and feature set as a new pair at a more accessible entry point.

Their precise imaging and wide soundstage make them excellent for gaming, as they help you accurately locate directional audio. However, because they are open-back, they are generally not recommended for professional studio recording where microphone bleed is a concern.

The included 3.0-meter cable is fixed to the headphones, and the ear pads are designed for comfort and longevity. While they are not intended for frequent user-swapping, they can be replaced if they eventually wear out over years of heavy use.
