The headphones I use everyday with my Walkman are the MDR-NC033Es which came with my E580. They serve their purpose quite well, are portable and minimize outside noise quite well. I needed new large headphones since I gave away my MDR-V55s to my younger nephew and was now left without anything for home use. I had a few options, first go for the Walkman WH-Series and use it headphones and have it as a standalone Walkman when I didn't want to take my E-Series. Second option was a small Bluetooth capable set, something along the lines of the Sony SBH80, SBH52 or SBH50 but the first one was not out yet and I don't think the sound quality of the headphones would be better than my NC033s.
So the final option was something else, perhaps wireless and with noise cancellation built in, something to use on my Xperia Z1 but have it wireless and with noise cancellation, but nothing like that in Europe from Sony. So I ended up looking at other Bluetooth enabled headphones, MDR-1RBT was way too expensive and way too bulky, any other model was designed for home use only and not very portable or light weight, others were not available in store or were back ordered on most websites. The only option were the MDR-10Rs
Rest of the review after the break.
