I bought a BlueTooth reciever from Walmart for $9. I found it hanging on the wall near where they sell HDMI cables and SD cards. There are plenty of others on Amazon. It has a 3.5 mm jack and stub that plugs into the 3.5 mm input on the Yamaha Stagepas 600I/400I. It charges off of my home computer and stays chrged for a very, very long time. I don't know how long because I don't keep track but I have used it for many times forgetting to charge it for several weeks in a row. I use a $65 Android phone over BlueTooth for my break music.(I haven't been using backing tracks for a while now). That's a spare phone that does not have a phone number. I suppose any BlueTooth playback device would work with it and a cable adapter to connect to any mixer/PA.


Does the noise in your head bother me ?
