The AIAIAI UNIT-4 Single Unit Black combines precise studio sound with maximum portability. This portable 2-way studio monitor offers up to 20 hours of battery life and is suitable for music production, critical listening, creative sessions and music playback on the go.

The UNIT-4 delivers clear and detailed sound reproduction with a 4-inch high-excursion woofer featuring a paper cone and a 1-inch silk dome tweeter. The frequency response of 50 Hz to 20 kHz at ±2 dB enables a precise assessment of music.

The 2-way bass-reflex design features DSP-controlled, volume-dependent bass boost. The sound can also be further adjusted using a 5-band EQ via the AIAIAI app.

Bluetooth 5.2 enables a straightforward connection to mobile devices. For professional equipment, a 3.5 mm mini-jack input and a balanced 6.3 mm TRS connector are available.

The UNIT-4 can be expanded into a stereo setup with a second UNIT-4. For particularly low-latency and uncompressed wireless audio, an X04 W+ Link transmitter (sold separately) can also be used.

W+ Link transmits audio at 44.1 kHz / 16-bit uncompressed, with 16 ms latency and a range of up to 12 metres.

Weighing just 2.54 kg and featuring an integrated ergonomic carrying handle, the UNIT-4 is easy to transport. Its battery life of up to 20 hours means it does not require a constant power supply.

The updated UNIT-4 can be charged via USB-C, allowing the use of a universal charging cable.

AIAIAI prioritises a durable design using 100 per cent recycled plastics. The housing is designed for easy disassembly, allowing key components such as the battery and driver to be replaced.
