AIAIAI S01 40mm driver speaker unit pair

Modular Speaker Units for TMA-2

The AIAIAI S01 is a pair of 40mm driver units designed as modular replacements for TMA-2 headphones. They use a lightweight PET diaphragm with a neodymium magnet to produce balanced audio across music genres. The units are sold new and come in black. Owners of compatible TMA-2 systems can swap them in to refresh or customise their sound signature.

Plug-and-Play Compatibility

Each unit slots directly into the TMA-2 modular framework without tools or soldering. The mechanical interface matches the original speaker mounts so alignment is consistent every time. Because they are delivered as a matched pair, left and right channels maintain identical sensitivity. No additional adapters or cables are required for installation.

Efficient Driver Design

The 40mm PET diaphragm keeps moving mass low, allowing the neodymium magnet to drive the cone with minimal power draw. In normal listening this translates to low distortion and negligible heat build-up during extended sessions. The open-back architecture of the host headphones handles venting, so the units themselves add no audible fan noise or thermal load.
