The best I can say about these headphones is that they're comfortable to wear. They look half-decent too -- good enough for you to appear as if you know about music when you're travelling on the tube, although they'll leak a lot of noise toward your fellow passengers.
Other than that, it's all negative comments. The sound is extremely bright, to the point of shrillness. It made me wince once or twice. The stereo field isn't very wide either -- it sounds like the orchestra or band are bunched up in the centre of your head, unless something is deliberately placed left/right in the stereo field, in which case the sound still doesn't seem to stretch as far as it might.
Yet the DR100s got a five-star review by What Hi-fi. Two things might have happened. Maybe the reviewer had a cold the day he got his hands on them. Or maybe Goldring have since swapped out some vital components from the headphones, as they claim on the packaging they reserve the right to do. I was a little disappointed to see that the speaker cones are held in place by a plastic grille that looks not dissimilar to the cheap over-ear headphones my dad bought back in 1982. It just doesn't add-up.
I expected more from these headphones. If you have any expectations of quality, then I'd advise you to audition before buying. These are not the bargains they're made out be.
