just incase anyone was interested the headphones from the new htc sensation with beats phone will work fully with the desire hd. i was dissapointed by the standard headphones that came with the desire hd and have been looking for something better for ages. unfortunately no-one seems to make any that work well with the desire hd. i decided to give the beats headphones a try and they work perfectly and dont seem to suffer the distortion and poor quality sounds of the standard set.
