What MP3 can I use to play my music from Itunes? And, will Bose earbuds (bluetooth) be compatible?

My MP3 is damaged and I need more GB's. I need at least 80 or more. Is there an MP3 out there for purchase that will allow me to play my Itunes through an MP3? And, which one would be compatible to my Bose earbuds (bluetooth) compatible?

Unfortunately, I have Itunes and can't play any of the music, which is on my desktop! Since MP3 are obsolete what do I do? I have all this music and can't take it anywhere with me unless I take my PC with me! Which isn't doable. To cart my PC outside to the beach, jogging, etc.... I don't have a Iphone and I don't intend on getting one. Sooo, can I still get an Apple MP3? And, which one would be compatible to my Bose earbuds?

Thanks kindly, in-advance
