I do not understand why Motorola quit making these headphones. I am a truck driver and have had several different styles and types of bluetooth headsets and headphones from cheap to expensive. These are the best I've found. I may have had one that sounded a little better when used with the mp3 player on my phone. I may have had one that had louder call volume on both ends of the conversation although volume is by no means an issue with these. On a whole, all features combined it is by far the best especially considering it is an older model that I bought used off Amazon. When used in the environment that I do there can be no better test as to the quality of a product like this. I have noticed that when a set of these comes up for sale anywhere that they sell quickly. They are no longer manufactured by Motorola, therefore can only be found as a used item. I got lucky and the set I purchased had been barely used if it was used at all. If you plan on purchasing a product of this type, I assure you that you would not go wrong by purchasing this set of headphones. I wish they would manufacture a product very similar to this once again. I would definitely buy one because I'm sure technology is a little better now and as compared to the other stuff I've seen out there it wouldn't take much for them to far exceed all the competition in every way, no matter what the price.
