Summary: I bought the Panasonic kx-tg7741 phone & this headset at the same time. The connector is slightly different in shape, making it slightly loose, which causes static. It's more expensive to return than the price. (My old Panasonic headset bought in 2005 fits more snugly & works better with the new phone.
Cons: Did not meet expectations, Poor quality, connector not precisely shaped
Summary: When I am long winded and don't want to bore others in the room listening to my phone calls, I can plug this earphone into the cordless phone which mutes the loudspeaker on the phone but I can hear on the earphone and talk into the included microphone.
Summary: Panasonic headset did not work with the Panasonic phone I ordered. Returned it to Walmart for credit. I was very surprised because I have been using Panasonic items for years and this was my first complaint. Ended up using my old headset until I can find a replacement.
