A Closer Look: HTC Boomsound on the HTC One M9

April 2, 2015 - Written By Alexander Maxham

HTC’s front-facing speakers, which they’ve dubbed Boomsound since the One M7 was announced in 2013, have been one of the highlights of HTC’s devices. It’s no different this time around. In fact, it’s even better. In the Snapdragon 810 series and later processors, Qualcomm has been working on something called Immersive Audio. It’s one of the many demos they had going at Mobile World Congress last month in Barcelona. And HTC is the first one to bring Immersive Audio to their smartphone, in the HTC One M9. Spoiler, it’s amazing.

I posted a video on my personal YouTube channel a few days ago showing the difference in sound between the two different modes on Boomsound. Which are Theater mode and music mode. You can see that video at the bottom of this post. Theater mode has Qualcomm’s immersive audio. If you don’t think it’s all that great, give it a try with an action movie clip or trailer playing on YouTube or another app. And turn the volume all the way up. I bet you’ll be amazed at what your $650 smartphone can do.

While the music mode in Boomsound is just what you’d expect, regular sound from your front-facing speakers. It still sounds amazing, but I personally prefer the theater sound for all the audio that comes from the HTC One M9. You can easily switch between the two as well. Going from Theater Mode to Music Mode is just as easy as pulling down the notification tray and tapping the icon, when audio is playing. When it’s not playing, you can change it from the settings. Just jump into Settings and under Phone you’ll see “HTC Boomsound with Dolby Audio” available there. Just tap on it and it’ll switch to the other mode.

As expected, HTC’s Boomsound is better than ever. With Qualcomm’s Immersive audio included it makes it even better. Qualcomm did inform us that all processors after the Snapdragon 810 will support Immersive Audio, that includes the teased Snapdragon 820. So it will be interesting to see how the other OEMs use immersive audio in their devices. Especially Motorola and Sony seeing as they do front-facing speakers now too.
