LG has announced new WiFi Music Flow speakers with a host of innovative features, Digital Spy said.

The company's line-up consists of the H4 Portable – its first battery-powered portable WiFi speaker – and upgraded WiFi Sound Bars, the HS7 and the HS9.

When the speakers are within a foot of a smartphone, the Auto Play Music function detects any music the user is currently listening to on their handset and plays it from the speaker.

This means that you could seamlessly listen to music on your phone while walking home and the music will relay to your speaker when you arrive home.

When connected with Line messaging app, it's also possible to control the speakers via text with message commands such as "turn off music after one hour" and "play songs for party".

Using the LG Music Flow app, users can play music from their Spotify and Deezer accounts too.

There's currently no word on pricing or when the new range will be released, but LG has confirmed that they will appear at CES 2015 from January 6-9.
