Smartphones  are great, They can do a myriad of things such as stream audio, play video and send emails and texts. However some of us are still using our phones to make voice calls. But many of are still experiencing "can you hear me now" syndrome where we're forced to move from spot to spot trying to find a clear connection. HTC claims to have solved the problem with the HD Audio feature built into the HTC Evo 4G LTE.

Thanks to a combination of dual microphones, encoders, decoders and some tweaks to Sprint's network, HD Audio delivers rich, warm audio in just about any setting. In addition to boosting the audio, the technology also blocks out background noise such as a noisy party or a windy corridor.

During our hands-on time, we entered a soundproof booth and had a phone conversation with a Sprint representative on both a HTC Evo 4G LTE and the original HTC EVO 4G. There was an immediate difference between the two phones. The Evo 4G sounded like we were talking on a cell phone with noticeable pops and hisses while the Evo 4G LTE was clear with rich sound. The rep upped the ante, blasting music  in his soundproof booth. While we heard some slight noise, it was negilable.

It should be noted that HD Audio only works on other HD Audio-capable phones which is a clear signal that the Evo 4G LTE won't be the last phone to feature the technology.
