64 Audio’s A4t is a new versatile custom in ear monitor (CIEM) that provides an affordable entry and their signature Apex module technology. The A4T is a quad balanced armature driver IEM, with 1 Tia high, 1 high-midrange, 1 mid-low, and 1 low frequency bass driver. This array of drivers provides a bassy, yet musical sound signature. With rich bass and clear highs, the A4T manages to effortlessly present music warmly and energetically. The A4T also contains LID technology, preventing the source from colouring or degrading the sound in any way, perfect for professional use as well as casual use through a smartphone. 64 Audio’s unique Apex technology also improves user comfort by reducing pressure in the ear canal.

The A4T is packaged with a personalised hard shell carrying case, which houses the earphones, the detachable cable (48” or 64”, picked on order), Apex modules (pair of M15 or M20 modules, picked on order), shirt clip, dehumidifier, cleaning tool, and sticker.

For a more detailed warm sound, consider the 64 Audio N8, or the more balanced sound signature of the 64 Audio A3e.

The A4Ts are a custom earphone, meaning that they are moulded to your ear canal. To order the earphones, please make sure that you visit an audiologist to have your ear impressions made.
