i know what a balanced output is. i am saying that there are dedicated audiophile-grade, battery powered bluetooth receiver DACs with balanced output, which you can plug any wired headphones into, usually through a 2.5 or 4.4mm jack so you don't blow up your cheap pairs. they usually come with a built-in mic and a lapel clip so you can use them to take calls. FiiO is a big brand that makes these, but there's a whole market.
