Came across this deal which is on offer for the next few weeks. These glasses are a nifty idea, sound quality is surprisingly good. I had the Alto but even the small sized frames were a bit big for my Asian head.
Great deal if you're looking for a pair of these.
Cheapest price that I can find and cheapest it's been on OzB. Discount will apply once you get to the last page in the checkout.
Nice find. Cool tech and decent sound.
