[ambient]

These are about three months old, they’ve had about thirty minutes use in that time, if that. I bought them because I tend to work late at night, and was disturbing my niece who’s room is next to my studio. These are are ‘open back’ type headphones, she complained she could still hear me. I’ve reverted to using my ‘closed back’ headphones that I’ve had for many a year.

These are in absolutely mint condition. They come with all the original packaging, all cables, basically everything they came with.

The price includes next day special delivery, so fully tracked and insured.

The technical details copied and pasted  from Amazon, which is where they were bought:

Not to dampen anyone's fireworks, but can you get Amazon to take them back?

They’re out of the return period unfortunately, you get 30 days. It’s annoying because they’re brilliant sounding headphones, the detail is great, and one of the reasons I bought them.

These are very very good. I have the older 600 series and they are both light to wear and have excellent sound capabilities. I have a friend who put me on to these as he had recorded and mixed a very fine sounding album in his home studio using a pair.

Still available.
