Video shows consumers comparing their headset to the HTC USonic earbuds
Inside the box with the HTC U11 handset comes the manufacturer's USonic earbuds. These have a number of features that you won't find on many headsets. First, the USonic scans your ears to find the best output level for you. The first time you plug in the earbuds, you are prompted to set up an audio profile. You can turn the personal audio profile on or off by going to Settings and tapping on the HTC USonic on/off switch.
HTC released a video yesterday that shows consumers trying out the USonic earbuds and comparing them to the headset they currently employ. While no words are spoken during the video, HTC says that the smiles on the faces of those with the USonic in their ears "speak volumes" about the accessory. The manufacturer says that this is especially true when you compare the smiles with the dour expressions on the same faces when they are using their own equipment.
