    Garbage Quality

    This is trash. It comes with a USB to A/C power cord, so make sure you buy a USB wall outlet to give it power. I reccomend not buying it at all. It's cheap, the connections are soft and weak. The sound and video pops in and out without tension on wires and with proper power input. This is 5-Below quality, honestly.

    Works, just not great!

    Worked, but could not get good sound out of it, should be used with some type of amplifier!

    Great for projector setups

    This worked wonderfully to grab audio from my Bluray player, which connects to a projector, so I can send it to an amp. It’s super easy to setup and did a great job. It feels solid and well-built. Plus, it didn’t mess with the video quality at all.

    Works well as a pass-through HDMI audio extractor (to analogue or digital audio outputs)

    This HDMI audio extractor works well with good audio fidelity to both the analogue output and the optical/SPDIF output.You can select between stereo, and 5.1 PCM on the optical cable. To use all 6 channels, you need a 6 channel 5.1 source audio on the HDMI input of course! (This unit does NOT support ARC or Audio Return Channel from a TV or monitor on the HDMI output.)The unit supports 4k video up to 60Hz over HDMI, and HDCP 2.2 - there are no problems with copy protection and the video is passed through unimpeded.

    Kan beter

    Het werkt, maar helaas moet je daarna wel handmatig de resolutie instellen, springt anders naar 720p, en CEC power on/off komt ook niet meer door vanaf streamer richting TV/beamer.
