Iqua along with Suntrica showcased their solar-powered headsets at the 3GSM in Barcelona recently. It seems to be based on their existing Vogue headset. Since facts are a bit sketchy, we can presume that an external solar panel will power the set. Other than the fact that it weighs 14 grams and may have similar specs as Vogue, little else is known at this point.

From the Press Release:
Imagine sailing with friends – most of them have mobile phones, digital cameras, MP3 players and laptops on the boat. When there is an opportunity to charge the batteries, everyone rushes to get their device plugged. With the new elegant Iqua headset, you can just relax, sunbathe and let its battery charge. With the BHS-603 SUN, you not only look stylish, but save energy at the same time.
