Item was purchased to replace a Motorola 300 headset. Worked ok but, paired fast. Volume was ok but could have been louder. Biggest drawbacks were callers could barely hear me if I was not using my 'outside' voice which is annoying to others around you. The other complaint is the fit. I still do not understand how Motorola engineers enjoy this design. It feels like it is going to fall off and on occasion does. Item was returned within 30 day policy of where it was purchased. Here is where I am at currently with headsets....this is my review for the cardo scala 700lx that I currently own and am very happy with so far. I feel the cardo is a better unit for comperable price.
