AIAIAI's TMA-2 Modular Headphone Speaker Unit provides a balanced sound that works with any genre of music. AIAIAI created this speaker unit using a neodymium magnet and a lightweight 40 mm PET diaphragm to support a flat and neutral sound while maintaining a high-end resolution and excellent mid-tone rendering. The housing of the speaker unit is injection-molded from durable ABS material and coated with rubber for a matte look.
