I also have a pair of Radians.
They work well, but are not very rugged. I'll be replacing them this year after about 3, maybe 4 years of service. They still work but they're pretty beat up and I've had to baby them to get them this far, and had to make a few redneck repairs to some pieces. I guess for the price I shouldn't complain. I paid $115, IIRC, but they're much cheaper now. Pay attention to the Noise Reduction Rating though. It was higher when I bought mine, I think. They're thinner now, with a lower rating.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
