I had a number of (mostly cheaper) Sony buds in the past, but I got the best sound from my MDR-E888's. They didn't turn out to be so durable though. I *think* they had more presence in the low end but for sure didn't have the same amount of treble extension, air to them or (micro) details that the Monks provide me. They were a bit more comfortable to my ears though, although as Lee already told me my ears really are adjusting to the Monks and they are becoming increasingly comfortable (can wear them for longer before slight discomfort begins, and no more pain. They gave me slightly painful ears after extended listening sessions at the start). Honesty commands me to point out that the quality of my source and format has improved from the time when I used to listen to the MDR-E888's though, and my experiences with those are just from (old!) memories. They were nice buds but from memory, as far as that is reliable (not too much
) the Monk's definitely outdo them soundwise.
