One way I use my Hearphones that might be interesting is in theaters. I'm a huge fan of musicals, and they're so much better with my Hearphones.
I have moderate hearing loss, and my hearing aids are really annoying in any theater - movies as well as live, but especially for live theater. The sound is tinny, and I do understand why, but it really takes away from listening to music. And they're terrible for fast volume changes - from lowest to highest takes 8 seconds, and beeps 14 times.
I have tried the assisted listening devices provided in theaters, and while they're a lot better than they used to be, they're still not very good. They amplify specific microphones (freqently in the orchestra, which I don't need to be louder), rather than just all the sounds equally. The Hearphones are much better. They're also great when a show is loud, or when I'm sitting too close to a speaker.
Of course using the Hearphones only works because I can control them without using my phone, just the buttons on the cord.
If Bose could replace the assisted listening devices in theaters with Hearphones, you'd make a lot of people a lot happier.
And thanks for really improving my theater experience.
