Ugh, put my headphones in last night in bed and was suddenly reminded how bad HTC are at audio. If any sound is played (including screen presses) then you get about a second of audible hissing followed by a click - it's terrible! As I listen to a lod of sport/tech/comedy speech based podcasts at night before I sleep at low volume it makes this device a no-go for me. Maybe I'm used to better quality audio now but I would say this is the worst I've ever heard.
