I must say that I was very skeptical of ordering a head set for less than $5 when Walmart sells the same thing for over $30 and when it arrived in 3 days in a small envelope instead of the prety plastic package at Walmart, my heart sank. I put it on my ear (that was easy and very comfortable), pluged it into my phone and pressed the call button on the mike. WOW!! This thing is LOUD and the mike is very seneitive also. I have 9 different headsets for my cell phone trying to find the right one, and now I have. I am ordering another one right away incase I loose this one.
