A:AnswerFirst of all you have to have a 2.5 mm Jack hole to plug it into. I have Panasonic cordless phones and most models have a jack hole on the handsets that the headset plugs into so you can roam the building hand free with the handset in your pocket. Check your handset for the jack hole. They do sell adaptors for 3.5 to 2.5 mm jacks.
