This is the second Jensen headset that I've had. The first one worked fine for several months, but then started getting a lot of static. I think it had a short due to the way the wire comes out of the top and then pulls down on itself due to gravity, which over time may be causing it to short out. I just bought a second one, because it had good sound while it was working. It is hard to keep the earphone on your ear because the part that holds it on your ear is bulky, but it is not uncomfortable. You also have to be careful to keep the wire tucked into something so it doesn't get caught on various objects while you are moving around. I use it with a Panasonic portable phone.
