Despite the LG G5 not being revealed fully until Sunday 21 February, the company has officially announced one detail early. The LG G5 will feature B&O Play audio.

LG and Bang & Olufsen's B&O Play arm have been working together to create an audio offering that is befitting of a flagship smartphone. LG says it will be the first company to offer "powerful Hi-Fi audio features co-designed by B&O Play".

As expected the announcement gives away little more than that. In fact it raises more questions. For example, how far does this partnership go? Will the G5 simply feature B&O Play speakers or will it be tuned too? And what about a DAC? There have been rumours that the G5 will be a modular handset that is able to add a DAC unit for even further enhanced audio.

Since high-quality music is fast becoming a sought after commodity, with streaming services like Tidal partially building their appeal on it, a DAC would make sense. This converts digital audio to analogue quality for a purer listening experience. Mobile DAC units are available but this will be the first time a smartphone has one that's made as a modular attachment.

Check back on Sunday 21 February for the official reveal at MWC in Barcelona where we will be to bring you hands-on details.
