i feel like a friend is accusing me for stealing her things?

So i usually would just use like a normal non-branded earbuds, but not too long ago i got an iphone with some apple earbuds. well, i didn't really tell my not-that-close-friends that i got a new phone, like im showing off like a kid or something, i thought they would have seen it since i use it all the time. And well, today, one of my friend said she lost her apple earbuds and when she said she can't find it and want to borrow mine, i just gave it to her. Then she said exactly" but why do u have apple earbuds? where did u get it from?" and i felt offended, as though she is saying that i stole it from her. I then briefly explain how i got it from my new phone and that i didn't think she didn't notice it.
Maybe she was just suspicious and maybe i was just overrating?

i don't know, but i don't want her to think that i stole from her because i didn't?
