Nowadays we're spoiled with options in the Bluetooth speaker market, and many of the high-end ones -- especially those from Soundfreaq and Nokia -- even feature dual-system streaming (DSS) that lets one speaker pair with another to enable true stereo playback. But if you already have a pair of old but nice-sounding speakers with 3.5mm input on both, then here's a quick and easy way to add Bluetooth to them. Dubbed Vertus, this Kickstarter project features the above pair of receivers based on CSR's TrueWireless Stereo, a nifty technology that's been made available since early 2009.
Similar to any DSS system, one of the Vertus dongles (the right channel, in this case) acts as the master to receive the stereo stream from a Bluetooth source, and then it'd throw the left-channel stream to the other dongle. So provided that your speakers have their own power source to amplify, it's just a matter of charging these aluminum dongles up (a single charge lasts up to 10 hours), plugging them in and then pairing the right receiver with your audio source. Simple! That said, at $120 this kit may struggle to gain traction in retail, so hopefully the audio quality will somewhat justify the price. Introductory video after the break.
