does anyone knows the difference in between MDR-NW750N & MDR-NC750?
In my opinion, it's just a difference in cataloguing and accessory type.
The former (with N) is built for Walkman or audio devices, so it doesn't have a mic.
The latter is built for Xperia or mobile phones, so it should come with mic.
You'll note that the former is under audio section in the Sony website and the latter is under sonymobile.
As for sound quality, i don't think there should be much difference.
However, in my Xperia Z3 music app --> Sound Settings --> Headphones, it lists:
1. NW750N: Sony noise-cancelling headphones for Walkman
2. NW750: Sony noise-cancelling headphones for Xperia.
So I'm a bit curious why they have a separate option for both, as I assumed the sound quality should be the same.
Btw, I have the NC-31 that came with my Walkman F886, and under the audio settings there is also:
1. NC31/NC033/NC33/N33S: Sony noise -cancelling headphones for Walkman
2 NC31E/EM: Sony noise-cancelling headphones for Xperia.
