I'm considering to grab a pair of closed-back headphones to go with my Hegel HD12 DAC on my computer as my Sennheiser HD800 (which I love) doesn't cut it all the time as the open-back design doesn't really work when there are lot of noise around in my living room while using them. So I'm considering to grab some great closed-back headphones which I can fall back on.
There is currently a sale on the MDR-Z7 in my country so I can grab them for 3'500 NOK, basically 350 USD when we consider taxes. I'm looking at these and the Beyerdynamic's T70 250 ohms for 4'000 NOK aka 400 USD. I tend to prefer headphones with good imaging and a wide soundstage. Which do you think would fit me the most?
The MDR-Z7 has a very different sound from any Beyerdynamic cans. The Z7 has rich full bass and an overall stronger but darker sound. I have the Beyerdynamic DT-770, but reviews tell me the T70 has a similar sound signature, with crisp neutral mids and treble, and a very slight "V" shape that assists low-volume listening when needed. I feel the Sony tends to swallow the mids at low volumes. The Beyers have bass, but nothing like the Sony. Neither can be described as bright or as studio monitors. I don't have much to say about sound stage, sorry, because after all both are closed-back cans, and when I want a wider stage I switch to my desktop speakers.
To me the Beyers sound better with classical, jazz, and most acoustic music, especially if there are vocals, while the Z7 sounds better with pop, rock, soul, and electronica. Your ears may be different in their reactions, but third-party measurements generally match my impressions.
Their earpads are also very different. The Sony has big leather pads that are very soft, comfortable, and isolating, but may get a little sweaty during long listening sessions. The Beyerdynamics have smaller velour-covered earpads that breath better. Most people are happy with the stock Beyer pads, but they allowed the helix of my big ears to press against the plastic, so I replaced those with angled Brainwavz pads which changed the sound a bit.
Edit: added the "V" thing.
