Interesting, to me I would never carry an additional independent hearing aid for this problem. I generally have my keys, wallet, smartphone, and possibly music headphones. If this could be paired in with existing headphones - awesome, otherwise I can't see many people adding an additional headphone to the aforementioned list without a larger problem. I do like the expansion of the Bose objective though with this.
