I have the older version which I really liked. Great value for money. I don't use them for exercise as they're uncomfortable to run in, but I like that they stay around my neck and expect that the battery/mic will be good quality as it is a bigger unit than just earpieces. This one works much the same but has these shortcomings (compared to the older version). Ear cords are shorter and sometimes catch. There is no storage for the cord inside the neckpiece as the old ones had so they are not as compact. They are generally flimsier.
