If your tablet/device has a 3.5mm audio jack (which is standard with most tablets) then yes you can. If you are unsure then I suggest you check the specification for your tablet and look out for '3.5mm headphone jack".
Yeah you can, standard 3.5mm jack. The only thing is the jack is the right angle sort, so if you have a thick case on your tablet it may struggle to click in. I have a short extension jack for my iPad so it fits.
