If you listen to bass music, then you won't be disappointed. If you want a more refined sound whilst having a portable can with noise cancelling and wired + wireless mode, the 1000X-M3s (regardless of the relatively high, but thankfully in Sony fashion, falling price) are a no brainer. If you just want a super lightweight fun, cheap and portable can, the MDR-1As are still recommended, just remember the very top end (>10Khz) is dull and you can't EQ it in convincingly. I haven't listened to the HD25s in quite a while, but I was surprised how good they sounded for on ear whilst being marketed for monitoring/mastering. Quite a tight clamp though.
