Hi kel.

You might want to check our Medword.com.com page on noise-cancelling headphones found here:

Noise-Cancelling Headphones

You'll find new and used ones available. We use (among others) Audio Technica over-the-ear noise-cancelling headphones and have found them to be excellent. Finding the right headphone set may be a hit-and-miss exercise.

Wishing you the best of health,
