Question: how to connect wireless headphones to guitar amplifier?
Answer: Simply plug your headphones into the headphones out jack and you're good to go. While many modern amps provide 3.5mm headphone jacks (1/8″ standard headphone size), some use a 6.3mm (1/4″) output (the same size jack as your guitar cable). You will need to use an adapter to connect your headphones to your guitar amp.
