IFA has always traditionally been an A/V show, and IFA 2017 is no different, with more speakers and headphones than you can shake a subwoofer at. What has changed however is the tech powering the tunes, with the speakers on show now almost entirely wireless streaming systems.

Case in point: the tidy-looking JBL Control Xstream speakers. Set to be sold as a pair, they come with Google Chromecast built-in, and also work with the Spotify Connect feature for physical-media-free streaming playback.
