Went to use my SUN-RAY Gold headphones on my 1270 yesterday and I got no audio, so I switched to my never used Audio 200's which wouldn't work either, both sets work in my F75 and my 1265X and my 555-D, so I tried and old used pair of Audio 200's I had a while and they worked ,so again I tried my really old SUPERPHONES and they worked. the older phones did not have great quality sound but they can be usable. Any ideas? I hate to have to send this back again.
