A:AnswerThese headphones connect to the headphone port on a non Apple laptop. They do not work on a iphone. You need to use Apple earbuds on an iphone. I bought these headphones because Apple earbuds will not work on an HP laptop.
A:AnswerSeeing as how you asked this question over 4 months ago you might have already made your purchase. For what it's worth, I'm currently using these headphones with my iPod Nano and an old Sony Walkman with AM/FM radio.
A:AnswerYes, you can, however, the cord itself is pretty short, so if you need to reach from deck to deck or off your setup they're going to yank off. I would recommend them if you were to practice DJing at home.
A:AnswerI am not very familiar with hearing aides (yet) but the set of headphones is quite snug in it's fit and the padded portion fitting over the ear is only about 3 in in diameter. Outside to outside. I can say that the arm of my glasses sometimes starts hurting against my ear because of it pressing. Hope this helps ...
