Refurbished Lightspeed headsets can be bought with a warranty from
Lightspeed. Two years ago I spent $200 apiece on 15k's for the whole
family and they are still good as new, 140 hours later. The only thing
I wish we had was an automatic shutoff for the *(($)&$ batteries---at
this point it would have almost been worth it to spend another $60 on 15XLs!
