Hi @Skylight2 Any bluetooth headphones that are A2DP compliant will work. This is the only standard that Glass currently supports.

I no longer have Glass (just a puck) but when I did my old Sony headphones as well as my newer Bose ones both worked fine.
I'm not sure what you mean by pucker box but assume you mean a stream puck (probably a spell checker issue - I get caught out all the time). The puck would be connected to a TV so your headphones would need to be connected to the TV and not the puck.
