Naturally, since it is GN ReSound technology, SuperTune™ does much more than just recharge batteries. For example, it can be powered via the USB port on any personal computer. And it has a series of indicators that keep you informed of the instrument’s status. For added flexibility, there’s even an charging compartment in the unit where batteries can be kept fully charged. So, if you’re looking for the latest attractive, high-performing instrument with the added convenience of a rechargeable battery, ReSound Pulse™ is the obvious choice.
