Sound bar accessories

[Mat2]

I bought a Samsung soundbar and these came with it and have no clue what are they!! 

Anybody can please tell me what are they?

Any body knows what are those things ?

Bluetooth speakers perhaps to get that surround sound effect. To put on the other side of the room from the sound bar.

@Mat2: Please can you confirm the full model number of the soundbar, and I will look into this further for you?
