I bought a pair of these (http://cgi.ebay.com/Vintage-Sears-Pioneer-Stereo-Headphones-Studio-SE-50-A_W0QQitemZ390036261577QQcmdZViewItemQQptZLH_Defau ltDomain_0?hash=item5acff90ac9&_trksid=p3286.m20.l1116) for $7 a while back, seem nice but seem to have the classic broken connection at the plug problem, just wondering if they're worth the time fixing. Thanks!
