The Audix A145 is a professional studio headphone with a closed-back design and is equipped with a 5 mm larger sound tube for extended bass response (Ø45 mm) compared to the A140. Its soft circumaural ear pads provide the necessary comfort for long comfortable work and music listening. Its ear cups can be rotated 90° to facilitate transport in the supplied case, as well as to allow quick listening with only one ear (known as DJ grip). The single-sided cable is detachable and, with a length of 1.8m, pleasantly long to reach necessary playback devices. If necessary, it can be conveniently replaced with a longer or shorter cable. An adapter to 6.35mm jack ("big jack") is included in the delivery.
