A completely wireless and cable-free DJ controller, Hercules DJControl Mix Ultra lets you bring the party with you wherever you go. The battery-powered decks can link up your smartphone or tablet via Bluetooth 4.0 to run Algoriddim Djay, which can stream from Apple Music, TIDAL and Beatport; pair this with some wireless speakers and you're ready to go. The concept is impressive, but we can't help but feel that the Mix Ultra looks like a bit more like a toy than a DJ controller. If you want an affordable solution for on-the-go mixing, though, it's certainly worth a look.
