Give your HTC One M8 the Harman Kardon treatment
The HTC One M8 is a great device, contributed to by the BoomSound front-facing speakers HTC have implemented on the device, but Sprint subscribers have access to an enhanced version of the M8 that includes Harman Kardon audio tuning.
Now non-Sprint subscribers can enjoy the same enhanced sound setup thanks to the XDA Developer forums as a tweaked version of the HTC One M8 can be installed on any model to enable the feature.
You’ll need to root your device to do so, but if you’re interested hit up the source link to head over to XDA Developers to find out how.
