@MJ Burton iPad should be fine. I play it off my very old iPod and it works.
One word of advice, if you're gonna buy the recommended earphones and because you have hyperacusis, buy the Koss KTX-PRO1's because they have manual volume control.
It becomes very useful if your iPad won't go low enough not to spike your tinnitus, the other ones don't have that and they're not as comfortable I find (I have both).
Start very slow, with the lowest volume possible. My target volume was way way lower than the recommended 30 percent for people who don't have hyperacusis.
The lowest setting on my iPod was actually too loud and I had to go lower with the manual volume control.
For that reason I think the sound is less effective but I can't listen too loud otherwise it spikes the tinnitus and is counterproductive. Good luck.
