audio technica ad700's have really low sound output

[keithy351]

Hello everyone, i just recieved a pair of audio technica ad700 headphones that i bought brand new from ebay, when they arrived i tried them in multiple devices and they are extremely low in sound output meaning i turn up the volume on all my devices up fully and still the sound output is what i was say about 20% my $10 logitech headphones will get 4-5x louder then what these will, is there something that im missing with these or could they be faulty

ok small update, i just plugged these into the back of my motherboard and the sound quailty has improved alot espically in games, but its giving a real echo/ listening to music in a hallway sort of output, is there anyway i can improve this? the front audio on my tower is screwed as its only outputting sound to one ear on all my headsets
