I think it is worth mentioning that besides the recently announced MDR-10R series, Sony also announced an improved version of their MDR-1R line of headphones, hence the MDR-1RMK2. I don't know too much Japanese, but here is are some quick points on the MK2's improvements over the original:
- Improved bass and sub-bass
- earpads and sound leakage
- independent rotational axis for the cups
- play/pause for iPhone and Android
- improved cable microphonics
- SmartKey app for Android
And just like the original MDR-1R series, the MK2s will also features the BlueTooth variant (1RBTMK2), but no ANC version, for that you will have to get the new MDR-10RNC., and the ANC version (1RNCMK2). For more information, please refer to the original press release.
Thanks to Speakerphile for pointing out my mistake.
