READ THE DESCRIPTION CAREFULLY BEFORE YOU BUY because the way the seller has described this item as a 3.5 to 2.5 adapter is deceptive. the description further states that it has a 2.5 female and a 3.5 male, which in my experience is actually a 2.5 to 3.5 adapter.if you have headphones with a 3.5mm jack and want to be able to plug those headphones into electronics with 2.5mm port, this is NOT the product for you. this will take your headphones with a 2.5mm jack and allow you to plug them into electronics with a 3.5mm port.thank goodness it was cheap, because it's totally worthless to me.
