Hello. I was looking for ways to manage and decrease noise in loud places, and stumbled across a few different products that interested me, mainly the Nuheara IQ buds, and the Doplar Labs here one's. These devices have microphones in them, and either let in, or drown out, sound from the outside world. Both have iOS apps to access these functions. Has anyone tried either of these products? If so, how have your experiences been? Do they really make a difference in how much noise you hear? And are the iOS apps accessible.
