Hi, my name is Sebastian and I am new on SoundCloud. I would like to use SoundCloud for an exhibition of my fotos in an art gallery. The people on the fotos should tell short stories about themselves via Qr code. The problem is, that the sound files can only be heared on the speakers of the iPhone. But I have displayed more than 60 pictures, so this will cause a great confusion und a lot of noise. Is there a possibility to actuate the earphones only? Thanks for your help!
