MDR-1R (Chester Tan)

Which Do I Prefer?

I feel that the MDR-1R offers a more comfortable listening experience, which I attribute to the tuned-down highs and warmer mid. The MDR-Z1000 is more punchy and exciting. Both cater to different music genres. I'm really happy with either of them.

And my usual advise applies: each of us have different audio preference. Price does not mean your ears will like it more. Visit the Sony store and try it out yourself, if sample units exist.
