I finally gave up on finding these from a U.S. reseller anytime soon, and ordered a pair from Amazon.it for 248.97 USD shipped. Amazon.es had them similarly priced for the last month (~187 €) , but just today raised that to 265 €. I was worried this might presage a significant hike at Amazon.it, so I jumped.
What also prompted me to buy now rather than wait for the supposed June release in the U.S. was this bummer of a message I received today from a rep at redmedia (redmedia.biz) that handles their Philips account: "I apologize, the news is not good. The retailer we thought will be carrying the L2s, will not be after all. At this time there are not plans to sell them online, but that may change as things get finalized for the year end."
In other words, if this person is getting reliable info from inside Philips, it looks as if the L2 won't be available from any U.S. dealer, including the online Philips U.S. store, until much later in the year, if even at that. Hopefully that gloomy forecast will prove wrong.
But what a bizarre marketing department Philips USA has, since they've been listing the L2 on their web site since Spring. I mean, if they're going to tout these headphones on their own website, the least they could do is offer them for sale in their online store. If you want a really good laugh, I called that store today, and was told I could pick up the L2 at Walmart!! It took some effort to bulldoze the news into that person's brain that the L2 wasn't for sale anywhere in the U.S., not even at the highly esteemed Walmart. They finally owned up to that after checking walmart.com, then excused themselves for a minute or two--apparently to confer with higher ups--and came back and told me the L2 in the U.S was being sold under a different model number: the X1. The deep breaths I gulped to keep from exploding!
