A 16ms wireless latency and uncompressed 44.1kHz/16-bit transmission via the included X04 W+ Link transmitter sets these AIAIAI UNIT-4 Gen 2 monitors apart from typical portable monitoring systems. This wireless studio monitor pair brings reference-quality sound to wherever music gets made, combining accurate 2-way active design with the flexibility to move freely around a space without trailing cables. Each monitor houses a 4-inch high-excursion woofer paired with a 1-inch silk-dome tweeter, tuned to deliver a flat 2dB frequency response from 50Hz to 20kHz with bass enhancement extending response down to 40Hz. Beyond the ultra-low latency wireless connection, the monitors accept Bluetooth 5.2 streaming plus both 3.5mm and balanced 6.3mm TRS analogue inputs for direct connection to laptops, audio interfaces, mixers and mobile devices. Battery life exceeds 20 hours of continuous playback, making them genuinely portable for location recording, bedroom production or taking reference mixes between different listening environments. The enclosures are constructed entirely from 100% recycled plastics, with a repair-friendly architecture that allows batteries and key components to be replaced rather than discarding the entire unit when service is needed.
