Idk, I feel like even the best ear plugs would still let sound in, and at least for me, sometimes having a little bit of sounds is almost MORE distracting than being able to hear perfectly. It's like my brain is working harder to figure out what's being said as well as comprehend it... I think I may just bring my splitter cable and plug my headphones into the TV (they have male and female, so my opponent could still hear).Have you considered using ear plugs instead of headphones?
headphones can be distracting in their own way. Ear plugs to completely block sound would mean your entire focus of attention would be solely on one sensory modality (vision), directed at the game.
