MY HD3 is fine for playing through speakers but as a walkman - totally useless. It doesn't go nearly as loud as it should for noisy environments. It's far quieter than my MD walkman or my dad's CD walkman (both Sony). If you turn the AVLS on it's almost inaudible - and my hearing is ok. Is there any way to boost the volume?? I don't want to spend loads on Shure earphones and they won't cure the output problem anyway. My other option is to return it to Richer sounds. They still do the HD1 for a reduced price - does that go any louder? I'm annoyed at Sony for releasing (in my opinion) a useless product.
