A:AnswerI'd say I have a pretty normal sized head and mine are on the smallest setting, they go pretty big. The ear cups comfortably surround my ears, so I'd say they're also pretty big
A:AnswerOn iPhone, iPad and Mac you can listen to lossless audio with these headphones, but these headphones would require a lightning to headphones Jack, During the conversion of analog to digital the signal would degrade and would result in a loss of audio. So not recommended.
A:AnswerHonestly, it depends on the item and the way your store has it. I bought an oled 4k Tv in an open box excellent condition, and it was prisitine, but the worker told me the TV came with the cable, but didnt come with the feet or remote, which at that point, buying the missing items seperate would be the same as buying it new. Same thing with a monitor i bought, it was "excellent" but came with no box and had to carry it out of the store fully assembled with a pickup sticker just slapped on it. I would just spend the extra money on getting a new one as i feel they dont inspect it whatsoever
