The UNIT-4 Wireless+ studio monitors from AIAIAI combine low-latency wireless technology with battery power, thus opening up a whole range of new options for creators who want to produce music on the go: The only cable that these compact and robust speakers really need is a charging cable. Loss of sound quality is a price that most users will not be willing to pay for this degree of freedom, however, but they need not worry, as the UNIT-4 Wireless+ speakers deliver a professional-level linear frequency response of 50Hz to 20kHz that can rival that of significantly larger monitors. Each speaker has a volume of three litres and a footprint of just 11.5x15.5mm, and tips the scales at just 2.5kg, which makes the set compact and light enough to fit into a piece of luggage for longer journeys and thus makes for a far greater degree of portability than conventional monitoring solutions can offer.
In order to operate the low-latency Wireless+ technology, the user will need the transmitter included in the scope of delivery, which can be connected to signal sources such as laptops. The UNIT-4 speakers are additionally equipped with Bluetooth 5.2, allowing them to be paired in the usual manner without an adapter, and as is now virtually par for the course with technical devices, there is also a dedicated mobile app (available on Apple Store now and coming soon for Android devices) with which the user can adjust the sound to suit the situation (and their mood) and change the colour of the LED ring around the woofer. With all of this on offer, it seem rather bizarre to not connect the UNIT-4 speakers wirelessly, but AIAIAI has nonetheless allowed for this eventuality by providing both a 6.35mm jack and 3.5mm mini-jack connection.
The AIAIAI UNIT-4 monitor speakers are a virtually unparalleled solution that provides a high-quality studio sound for users creating on the go, who can thus take their production sessions out of the confines of the studio and work wherever they like - whether it's in a holiday apartment, at a friend's place, or in the rehearsal room. With up to 20 hours' operation on a single battery charge - and the added bonus that the batteries can be fully recharged in just two hours - users can also work for long periods without worrying about running out of power. The speaker housings are made entirely from scratch-proof recycled plastic that is robust enough to handle life on tour, and the strategically placed rubber strips provide additional protection and decouple the speakers from the surface on which they are placed. The bass reflex openings in turn double as carrying handles, while the protective metal front grilles are held in place by magnets.
The Danish company AIAIAI was founded in 2006 and produces headphones exclusively. Instead of offering a wide variety of different headphone models, Aiaiai has developed a modular approach, by which components are individually selected in order to create a final, customised product. To this end, AIAIAI has an online configurator which tailors each pair of headphones to the customer’s specifications. However, the idea is not only to create personalised headphones but also to ensure their sustainability. Instead of the user having to purchase a completely new pair of headphones if a defect occurs or if their application or sonic expectations change, AIAIAI offers its customers replacement, retrofit, and upgrade parts.
Whether they are on tour, meeting up with friends for a jam in the park, or having a relaxed music session at home, users can always be sure of studio-quality sound from the AIAIAI UNIT-4 Wireless+ speakers, with the added bonus that they have been designed to be repairable: With just a pair of screwdrivers, the speakers can be opened up and the defective component quickly replaced, whether it's a battery that has reached the end of its service life or a driver that has worn out. All of the larger components are made from 100% recycled plastic, and AIAIAI offers a range of accessories that include a bumper case made from recycled silicone, a high-quality carrying case with space for both speakers as well as chargers and other accessories, and a set of silicone isolation pads that are designed to enhance the stereo image and clarity of the sound produced by the speakers.
The widely popular Bluetooth technology delivers a high-quality audio signal, but this is still far inferior to the standards found in professional applications, with potential signal dropouts, noise interference, and most of all a high level of latency (80ms or more). AIAIAI's Wireless+ Link technology, on the other hand, delivers an extremely low and consistent latency of just 16ms, which is achieved through features such as a dual-antenna design and, thanks to the barely perceptible delay, allows audio productions (such as instrumental mixes) to be created and MIDI controllers to be used in a far more direct manner than with a Bluetooth connection. And while even the best Bluetooth codecs are no match for uncompressed audio, W+ Link transfers audio data in CD quality (44.1kHz/16-bit), with the added benefit that this larger bandwidth helps to prevent signal dropouts and interference.
