I have no idea yet what the price will be but today's (Sunday 8/7/2011) 10am-PDT
Lightning Deal is Sennheiser's HD600 headphones.
The deal is only good from 10am (PDT) to 12 noon or until they run out so there was no time to wait for the deal forum to let members know about this. Not all of their "Lightning Deals" are huge bargains but the really great deals sell out fast.
I own a pair of these from my condo living days and they're wonderful headphones but please note that HD600s require a lot of power and that your iPod isn't going to drive them. Most receiver headphone jacks will do a good job driving them but a dedicated headphone amp is probably a good idea.
Here's their
non-sale page with lots of reviews.
