The AIAIAI UNIT-4 Wireless+ is a high-performance, portable studio monitor built for creators who need reference-quality sound anywhere. Featuring a 2-way active design with a 4" paper cone woofer and 1" silk-dome tweeter, it delivers accurate, neutral sound with bass response extending down to 40 Hz. Powered by a long-lasting battery with up to 20 hours of playback and featuring AIAIAI’s proprietary W+ Link wireless technology, the UNIT-4 is made for professionals on the move.
The 2-way acoustic design uses a 3 kHz crossover and delivers pristine audio from a 4" high-excursion woofer and 1" silk-dome tweeter. With a frequency response of 50 Hz – 20 kHz and low-end extension down to 40 Hz, the UNIT-4 offers studio-grade monitoring you can trust.
Experience stable, uncompressed, ultra-low-latency wireless audio. Unlike Bluetooth, W+ Link ensures 16 ms latency and CD-quality (44.1 kHz/16-bit) audio with no dropouts, using dual antennas and a wider bandwidth for interference-free performance.
Weighing just 5.5 lb (2.5 kg) and featuring an integrated carrying handle, the UNIT-4 is easy to take on the road. Enjoy up to 20 hours of battery-powered playback, with full recharge in just two hours. LED ring indicators keep you updated on battery status.
Connect via Bluetooth 5.2 or wired using 1/4" TRS and 3.5mm aux inputs. The included W+ Link USB-C transmitter adds low-latency wireless support for compatible devices. A dedicated mobile app lets you fine-tune EQ and settings from your phone.
Made from 100% recycled plastic with a glue-free construction, the UNIT-4 can be fully disassembled with just two screwdrivers — making upgrades and repairs easy and sustainable.
