SnxiwthHDMI to HDMI and Optical SPDIF 4K Audio Converter with 3.5 Mm Stereo HDMI Audio Extractor HDMI to SPDIF Splitter for Apple, TV and Blu Ray Player

Metal cased unit, seems to be well made. Simple to use, powered from external usb. I am using the audio extractor with a HDMI PC monitor and soundbar. Audio works fine into the soundbar either with the optical output or the analogue audio.

This splits the audio from an HDMI signal and delivers it through a digital optical socket. It serves a narrow purpose, in my case connecting a modern Apple TV to a new projector while routing the audio to a 20 years old (but perfectly serviceable) stereo system, but does it well. It is powered by a usb port and it is important to plug that in first so it can recognise the hdmi signal. It saved me having to invest in a new amplifier.

I bought this to use with my Amazon firestick. I have it in my office connected to a computer monitor so no audio available. You can plug in headphones but there is no volume you can adjust to make it louder as this is a pre-amp output to go into an audio amp. The output is too low to use a 3.5mm jack to connect to an Amazon Echo or similar. If you thought you could use to connect to a bluetooth speaker then this is not for you. It has HDMI pass thru and an optical output to use a TOSLINK to connect to an audio amp if required.

Didn't open until 2 months after my order. Completely useless, outputs no hdmi signal, not even recognised by any device so impossible to know if hdmi input works. Audio outputs bunch of noise regardless of what is connected or not. At this point anybody can sell a box with ports on it and claim it does something it doesn't. Complete robbery.

I’m using this product to make an external monitor a fully functional ‘tv’. Before this if you attached a chrome cast into the back of the monitor the video would work but since there are no speakers in the monitor there was no sound. My monitor had no option for audio out so in theory there was no way for this to work. This product makes it possible. Now you do need external sound as well. I bought speakers that use an aux and usb. My device is on the PASS setting all the time and works perfectly!

I purchased this in March 23. It worked fine up until shortly after March 24. Then it started to create clicking sounds which I've not been able to get rid of. This is a shame because it was a perfectly good product until then.

My old TV refused to pass 5.1 to the Sonos so I has to use this to and the (Sonos) SPIFF to HDMI adapter to get the the XBox surround working.

Good product - this extracts the audio from the HDMI output of Xbox 360 console. A bit fiddly to set up to be honest but once sorted out the audio is extracted from the HDMI output to any external speaker or sound system. Good value and does the job.
