I found these to be hit and miss. Since they didn't work we moved to old school wired splitters or another solution like the headphone jacks on a receiver.
Since it is a soundbar, just get some optical to analog convertor then split the analog out to two places. Cables, convertors are numerous on Amazon so stick in the top 20 lists there.
I want to connect my LG TV from the optical output to an exterior soundbar (for my wife to control) and a transmitter for my hearing aids (for me). Both soundbar and hearing aid transmitter have optical inputs and both need to operate simultaneously. I have tried a passive splitter (no power input) and it didn't work. Any suggestions for a solution?
