Not yet, still to new and to hyped to have a sale. They are flying off the shelves right now so doubt we'll see a sale on them anytime soon. I'd keep and eye on eBay and wait for someone to list a slightly used pair like this here.
Or Amazon who looks like they have had a few returns that are in like new condition and missing nothing.
This is about the best deal going on the M-100s right now. A friend got one of these returns from the Warehouse Deals and they were still sealed. May want to snag one of those. You still have the 30 day return through Amazon.
