Stereo BoomSound speakers are among HTC One (M8)'s most premium features, so it will not be a shock to users if HTC is equipping the upcoming One M9 with similar audio capabilities. But it might be a matter of fact, if they do not turn out to be similar, but better.
HTC,suggested that the One M9 will have more powerful BoomSound speakers. The company posted a short teaser video on Twitter, alongwith the comment "get your hands on bigger boom." The video which has been embedded below, doesn't really reveal much, but it's pretty clear that we should expect the One M9 to have very loud speakers.
According to a previous report, HTC may have partnered with Dolby Laboratories in order to pack Dolby 5.1 audio technology into the One M9. Like Samsung, HTC will announce its next flagship handset on March 1 at MWC 2015.

The new flagship smartphone will most probably have two variants: One M9 (with a 5-inch 1080p display), and One M9 Plus (with a 5.2-inch Quad HD display). We assume that both will feature exactly the same improved BoomSound speakers.
