Lauded in the music world for their innovative products, Teenage Engineering are back with the Game & Watch-inspired Pocket Operator series. Collaborating with fellow Swedes, Cheap Monday, the Pocket Operators are available in three different versions, the PO-16 Factory melody unit, PO-14 Sub bass synth and PO-12 Rhythm drum machine. Each with 16-step sequencing, 16 sounds to choose from and 16 additional effects, the tiny music-makers can turn out some pretty serious beats, despite being powered by just two AAA batteries. The stripped back synths come with a low-tech speaker though outpout is high quality through the audiojack, and are available from the Teenage Engineering online store for €69 each: www.teenageengineering.com
