Product fix as needed on my phone.
Service and delivery was faster than expected

The product does what it is supposed to do. I can hear VERY well through my personal headphones when people call and they can hear me through the mic on my headphones. I am using Skullcandy headphones in my office as it is much more comfortable.
I have only been using them for one day and it seems to be working just fine.
Delivery was a bit slow. Other than that, no complaints.
