Can anyone please confirm what is the output mode of the type of MP3 player shown in the attached image? It appears to be a Chinese copy of a well-known brand.

Push/pull? BTL? Or ...?

Please excuse me, but I don't have one here that I can test directly.

It will be push/pull, it can't be bridged as headphones have a common ground connection. There's also no reason, or point, in a bridged amplifier as high power isn't a requirement.

Do any of those little player thingies use class D amps?

Quite possibly, as various small audio chips are class D, and it would use less current.
