I bought this headset to use with my cordless panasonic phone. I pluged it into my home phone and was Very surprised when it ruined my phones they no longer work I have to put them on speaker to hear anyone now. The headset fit but all I could hear was a fuzzy sound, now I have two panasonic phones that I can hardley stand to use. I don't remember seeing a warning that these are not compatable with my phones. Can you please replace my phones or do I now need to spend another 100.00 for new phones? My phones are only 4mo's old.Please get back to me about what you can do for me.Thanks,Rachelle, Burlingame, CA
