Price : $500.00 in Japan and $750.00 in USA via www.audiocubes.com
These are my current favorites. Awesome sounding headphones with plenty of bass and unbelievable resolution. I find myself listening at lower levels than I would have imagined possible...fantastic musical experience.
There are two other versions - SA1000 and SA3000 for those on a budget.
For those with no budget cap - there is a Sony Qualia 010 headset for around $2500.00
