Back in 2019 I asked about adding a bluetooth adapter to my Valkeryies. Found out Empire Ears have a recessed port for the cable / adaptor.
For some reason I decided to take another look at this setup. Since I'm a dentist - transforming that little acrylic port to a recessed circle instead of a rectangle is super easy to do. I just needed to make sure no acrylic shavings made it into the ports / connectors. I'm not using my Valkyries very much, at all, these days so I've decided to permanently alter the Valkyries - to go for it. The cable didn't really sit inside the recessed port well, anyway...
The Fiio UTWS5 won't be arriving until the middle of next week. I'll update if anyone is interested. I can't be the first guy to do this...
