Also note that the Kanex can only have one type of audio jack connected at once. That shouldn’t be a problem for most people. But if you swap among sources, be sure to unplug it from its power cable, remove one audio and replace the other, then plug the power adapter back in. With two plugs jacked in, Kanex says you’ll encounter problems.
Kanex notes, I suppose for completeness, that its adapter doesn’t block AirPlay mirroring to the Apple TV. It’s really a straight HDMI passthrough, so it shouldn’t, but I expect some buyers want additional reassurance.
The $60 price tag is the only thing that’s going to be a sticking point for some. You can get splitters with some part or all of the functionality for a third to half as much. But those come from no-brand-name companies, have few online reviews, and typically have an industrial look to them compared to the sleek shiny black finish of the Kanex model. These off-brand items also occupy about four to six times the volume of the Kanex, which is quite compact.
Kanex’s Digital Audio Adapter for Apple TV is elegant and comes with the backing of its reputation for managing technical support and manufacturing problems. For a plug-and-forget it device you want to work reliably, the extra price likely doesn’t work out to extra in the long term.
