So I just got two new HTC One Vs from VirginMobile's cyber Monday deal and everything works great except the quality of the sound when I am making a call or checking voice mail. It sounds like the audio is being digitally modified (think auto-tune). Its annoying and difficult to understand most of the time because everyone sounds like a broken up robot. The sound is bad through the earpiece, the speaker phone, as well as through headphones plugged into the speaker jack. I plan on calling VM technical support and possibly returning the phones, but I'm not certain if its the phones or VM network. Any clues?
