Update: cheaper from DWI, see comment below
============
Grabbed a pair of these and also the HDR-170 part (another set of headphones minus the base station)
Fantastic reviews. Can use upto 4 pairs of headphones with the one base station.
Coupon gives $5 off
I ordered RS-170 + HDR-170 with $39 shipping for $319.00
I own these, I like them. Great sound quality, distance is okay but don't let a wall get in between you and the base station.
