Samsung s425g/Evergreen headphone

So I get my new slider phone, find a microsd card for music, then realize there’s no 3.5mm headphone jack. So I’m wondering which would be more efficient/cheaper:

Micro-b usb to 3.5mm


Bluetooth to 3.5mm

Thanks in advance for the help!

For which Samsung phone?

They’re the same phone I think.

Yeah but what is the name of the phone? Is it the intensity? You said its a slider phone. So it’s got the super small headphone port or what?

It’s an Evergreen. No headphone port whatsoever.
