Beyerdynamic DT 660 and DT 860 headphones
I liked Beyerdynamic's DT 880 headphones, but I wasn't exactly champing at the bit to review the cheaper DT 860 and 660. I didn't think they'd be interesting, because at a glance they just looked like somewhat cheaper versions of the 880. They're not a lot cheaper than the 880, so I figured they'd probably offer about the same value for money, and I'd end up doing the usual bunch of product photography and then only write six paragraphs of review.
There's more to these headphones than that, though. The 860 and 660, while they're very similar to each other, are actually quite different from the 880.
