This is the 5th part of my wishlist to audiologists and accousticians, hearing aid manufacturers, and the health care system. If you like to add something, share your experiences, or provide more information, I encourage you to submit a comment.
Peripheral hardware often needs their own batteries. Those are very often proprietary batteries and most often they don’t last very long. For example in order to use my bluetooth adapter a whole day, I need to buy an extra battery for it and often a charger station as well (if available at all). And situations where this is necessary are common for example when you travel have nothing else do to than listening to music while sitting in the air plane for 12 hours.
I would rather prefer peripheral hardware to use normal non-proprietary batteries which are available in every grocery store in the world and that I can use my charger for normal batteries for. And please don’t tell me those proprietary batteries are necessary for the design of the devices, most of them look dorky anyway, so I might at least have the benefit of using non-proprietary batteries.
