For most of us there’s the iPhone stock headphones. For some of us there’s the Beats by Dr. Dre and for the guys at Head-Fi.org, there’s the Audio-Technica ATH-W3000ANV 50th Anniversary Headphones.
The ATH-W3000ANV headphones is slated to be the top model of the W Series of Audio-Technica headphones and is limited to only 2,000 units worldwide. The ATH-W3000ANV sports some pretty serious stuff like 53mm drivers, high quality wood earcups and lambskin earpads. It also includes a custom designed amp as well.
Pricing information isn’t available, but I wouldn’t expect these to be cheap. More info in the link below.
