Pros:Looks cool, adequate sound quality, grabs attention
Cons:adequate sound quality
The Bottom Line: If you want something that looks cool and are willing to pay for it then these are nice.
These are fairly good sounding headphones but are being sold at an exorbitant price. For $160 you can get some VERY nice headphones from etymotic, Shure, Grado, Sennheiser, AKG, the list goes on. These do serve a specific purpose though. They look awesome, they are comfortable, and did I mention they look awesome? How much you want to pay for that depends on what you're looking for.

As far as sound quality these aren't really much better than Sony headphones that sell for $50 or so. The quality of craftsmanship on the A8's are fantastic though but it's a shame they didn't put as much engineering into the sound quality. Bass is nonexistent and the mids are tiny. The sound is not as dynamic as I expect on headphones that cost this much.
If you appreciate good hardware design and care about looks then these may be for you. But if you don't mind looking like a doofus you can spend the money on a set of headphones from Sennheiser and enjoy VERY good sound quality. It's a matter of preferences, really.
BTW these do match really well with the new silver iPod Nano. The headphones really are eye turners and you can see them in movies once in a while. I know I saw the distinctive steel look on Minority Report. Bang and Olufsen also makes similar looking headsets for use with iPhones so you may want to look for those if you splurged on the phone.
