LG says its "transforming" sound bar, the SJ7 Sound Bar Flex, is now available for $450, £499 or AU$899.

The SJ7 consists of two detachable stereo units that can be used as fronts, rears or as Bluetooth speakers.

One speaker acts as the master while the second unit connects wirelessly and features an onboard battery. This second unit can be used as the wireless rear or for streaming Bluetooth anywhere in the house. The system appears to have a switch that determines which mode the second unit operates in.

The sound bar comes with a separate subwoofer, and the entire system features a claimed output power of 320W.

While the SJ7 offers an HDMI input it's only 1.4-compliant, meaning it won't support 4K TVs. If you want this capability, try the SJ8 instead.

The unit was announced at CES 2017 in Las Vegas, but the idea of a modular sound bar isn't new; the Philips Fidelio B5 with its detachable wireless rears came out in 2015.

Update, May 30: Added pricing.
