Sony Ericsson is set to unveil a "world first" product in a live webcast on Monday morning, that promises to change the way we listen to music "forever".
What Sony Ericsson has up its sleeve is anyone's guess, but the confirmation email we received when we registered for the webcast said we could expect a "new and innovative product experience".
We'd expect the new phone will fall into the Walkman branding, and we've been promised a live demo on the webcast so we'll have a good idea at what the handset can do.
It's all a bit vague, but all will become much clearer on Monday – of course we'll be watching live and reporting all the news back to you as we get it.
