Hi, I've started to live stream a bit during the last year and just now added headphones to the mix. I started to wonder whether my audio interface can actually supply enough power to both a condenser mic and a pair of headphones. I figured out that newer USB standards allow for more power hungry devices, but does that in any way help with a USB 2.0 device? My interface is the same old Edirol UA-25 that I've been using for a couple of years now. It is USB 2.0 and bus powered. It needs to supply a Røde NT-1A with phantom power and drive my new AKG K702s at the same time. I noticed that I need to increase the output gain a fair bit to get a good level (roughly at 50%-60% whereas I have it at 20% with speakers). The rig I run this on I built last year, it is based on a ASUS PRIME B350-PLUS which provides USB 2.0, USB 3.0 as well as USB 3.1 ports (although I can't tell which USB 3.1, way to go on that naming scheme, my only explanation is they ran out of numbers). I don't have other gear to compare, do you think the UA-25 can handle it properly? Is it any help to plug it into a USB 3.0 or 3.1 port?
