I replaced my original pair of headphones of the same brand with this model. This must be a different model than my original headphones. The 10-level tuning push button on my original pair is was replaced with a tuning wheel on the new set. My mother in law is hard of hearing and uses the headphones which allows my wife and I to hear our TV in the other room. Unfortunately my mother in-law also has no manual dexterity and she is constantly touching the tuning wheel loosing the audio.Make sure you upgrade to the model with the tuning button if the headphone are for an elderly person.
