Turn your iPhone into a DJ booth

Hailed as "the most powerful after-party weapon known to man" by someone who's clearly never done drugs, the U-shaped, pocket-sized Slussen's a stylish, dual-port audio jack that'll connect your phone with a pair of headphones and a sound system, and when used in combo with its dedicated app, transforms into an uber-portable DJ station.

The free app's equipped with all the tools you need to channel your inner DJ Paul Rudd (note: not actually Paul Rudd), including an equalizer, crossfader, and virtual turntables, plus for seamless transitions, lets only you preview on-deck tracks through the 'phones.
