Query: forget the phone

Worked fine with an mp3 player & w/ excellent sound quality, however wouldn't work w/ my mobile phone. W/ the phone I could only get it to work by jiggling the plug in & out of the jack. Pushed all the way in it didn't work, but it did work if I held it in place half way out. Even then, it would only work intermittently... Paid less than $2 so I'm not screaming bloody murder & won't bother asking for a refund.
