"Great w/ Verizon Flip phone, hands free talking"
I use w/ my Verizon flip phone w/ hands free talking driving my Big Rig state to state. People hear me clearly, I hear them good unlike Bluetooth type threw truck radio. I've only used about 10-Hrs. making 30 to 50 phone calls. I don't suggest driving & talking as it's a distraction. The 3.5 mm plug fits phone jack, however it came w/ second jack of different size. This has an on/off switch on about a 10' long cord to disconnect after call. I close flip phone after placing call & my call stays connected. These are comfortable to where, and well made & a good value for the money.
Amazon Prime w/ great S&H also. Ten-Four Ol' buddy
