I ended up having to buy a sound card as my MOBO didn?t have optical (Creative Sound Blaster Z has been working great for me so far). I think the BTR 5 is deserving of audio awards. Let me preface by conveying this simply truth; if you?re easily scared or new to VR, take it slow on this one. Then I put the 5s (4X) on the bottom center peg,& the locks on the top center pegs. Battery life is as advertised. But it also is prone to gets twisted on loops which will eventually result in damaging the delicate copper wires from within. This makes slewing target sensors a snap and it has a push down button adding even more true hands on. Lovely leather slippers with a warm, fluffy lining. Runs a half size too small. We ordered these for my five year old son to use as a slip on shoe for summer when he doesnt want to wear socks.
