The first pair of over-ear headphones I have purchased that I really like.
I did my research, as there's not a lot of info here. so:
They have 50mm drivers, giving a response range of 5 - 40,000 Hz which is a very good range. Not the lowest for bass (like the XB700s which look a bit bonkers), but very reasonable, and with a lot more high end response.
Easily driven from an iPod, no problem.
Sound wise, I'm more than happy. A good, balanced sound that's neither bass heavy nor tinny up top.
They feel well made. Plastic arms, but I found no complaints elsewhere about fragility. They do not fold, which you may want to think about if you're going to carry them a lot.
Very very comfortable, with reasonable noise isolation.
The arms allow some movement of the headphones to swivel, so they fit nicely, and the design has the ear pads angled, rather than expecting the band to sit on top of your head precisely in line with your ears. It means they fit very well, and do not feel like slipping off.
Not too hot and sweaty either if worn for a prolonged period.
The lead is integrated, which I ideally would have liked as separate plug in, but it is quite a substantial piece of wire. There is also an extension lead included.
No carry case included, or bag which is a bit of a downer.
Well reviewed on you tube by the likes of innerfidelity, if you want to check it out.
I also think they look better than pictured, if a bit retro.
