"We haven't heard much from the Kleer / DigiFi combo since they finally brought their first Opera wireless earbuds to the US at the beginning of the year, but they're now back with not one but two new sets of 'phones, including the follow-up Digital Opera S2 and the Made for iPod Digital Opera S5. As you might suspect, both models are mostly identical, and pack the same 32 foot range and ten hours of playtime as before, along with the usual promise of uncompressed, CD quality audio. The S5 model, however, adds an iPod-compatible transmitter and some control buttons right on the headphones themselves, while the S2 opts for a basic 3.5mm-based transmitter to accomodate your non-Apple gadgets. No word on pricing just yet, but both should be available on June 20th."^^<http://www.w3.org/2001/XMLSchema#string>
