A:AnswerIf there is a headphone jack…yes you should be able to plug them into your tv. You may need to change the tv’s output settings to hear via headphone. And cord length may or may not be an issue depending on how far away from the tv you plan to listen from.
A:AnswerI don’t.Know anything about the number 6.35 mm. I just know that the headphones have a typical round connection to a headphone port in my mom‘s hearing device microphone of her pocket talker. She likes how they fit and how they sound. She has a small head.
Sorry, I couldn’t be more detailed.
