i bought the white/black jawbones.
At the time there were 3 different item listings for these on DX and I just went with the most expensive, as there were a few stories on here re some being bobbins. Think I paid $17.50 or $19.50.
Very pleased indeed with them. Really good quality (both glasses and accessories) when compared against another model of real specs from the big O. Perfect for biking.
