I used to have a Motorola H500 which worked well for my phone. Unfortunately I misplaced it. So I eventually bought another one via Amazon. When I got it, it worked but had a hissing and crackle sound. I thought it was my phone and the problem would eventually go away. It did not. This was suppose to be a brand new headset. It's defective and I did not return it immediately. So I'm giving this supplier a 1 star.
