My old electronic custom plugs are from Starkey (Starkey Magnum Ear). Starkey spun off at least part of their hearing protection business to a new company called SoundGear. I have ordered a new pair of SoundGears but I have not used them yet. On paper, there are lots of improvements, including the ability to stream phone calls and other audio from your cell phone without compromising the hearing protection. Some health insurance plans will provide partial coverage because these are considered (by some plans) as hearing aids if you already have a significant hearing deficit.
