4K 120Hz HDMI 2.1 Switch 4x1 eARC Audio Extractor VRR ALLM HDCP2.3 ARC HDR10 CEC SPDIF Optical and 3.5mm Audio Out,HDMI Switcher 4 IN 1OUT IR Remote D-olby Digital EDID for PS5 XBOX NVIDIA AMD

Purchased Sonos Arc with no passthrough. This is feeding from Sky Stream, Apple TV and Blueray. Encountered a quirk with the optical out to my Sony headphone base station with Apple TV - I just forced Apple TV into 5.1 output and that sorted it - minor issue if I don't want to disturb the neighbours. Sonos App shows Atmos is present - not that I would rave about the impact of Atmos on the Arc. Guess I need Era 300 surrounds - sigh! Compatible with my Harmony remote which helps.

Had so many issues with this so returned it. Kept needing to be rebooted, loads of audio dropouts all the time and incorrect audio being sent randomly.

The ease of use, the sound quality, picture quality and 4k support is an absolute game changer! I had been struggling to get anything remotely looking like DTS Surround from my LG TV, this little box means I can now have DTS (not MA/X because I have a Sonos) but I have even got a way of mixing down the DTS MA to Dolby 5.1 with the click of a few buttons. Great value for money and would highly recommend.

Well, it works. It's not 100%. Hopefully, I'll get an update? Playing a 4K Star Wars movie very now and again the soundtrack cuts out of a split second, And it's very now and again! It can be very frustrating as it is random. It done it again on the 4K the Abyss . But it seems ok on the blu ray! But I will need more testing as I haven't played all the way through on a blu ray at the moment. It seems ok on streaming .But I have a problem with the sound as it's not as loud as the HD fury and it seems to have a small A/V Sync, but I'm not 100% sure on this. It as Sorted out the rainbow effect on my Optomo that's one good thing. One thing I don't like is the plug in for the remote. Hopefully the next one will be better! A week later I'm happy to say it works 99% I'm still not happy with the A/V sync on the 4K but a cheaper then a HD Fury. I'm thinking about getting one more 🤔. Update you need to reset it sometimes ie unplug it to get working again fully ie get Dolby Atmos back. Still not 100% on blu ray. I'm going to fit an on/off switch on the main lead so I won't need to unplug it or take out the main lead out of the back of it. It's my work around as it be easier for me in the long run.

I got this to switch between my Sky Q box, Apple TV, PS5 and Series X to my projector, whilst taking an eARC signal to my Soundbar.It does all of this perfectly, no noticeable lag whilst using the consoles and the 5.1 has never sounded so good. The remote makes it easy to flick between the four inputs.For this it gets three stars. It loses two for being an expensive unit that needs to be rebooted every single time you want to use it. Even if it’s only been off for 10 minutes.I hoped going through the painfully bad Chinese translation of updating the firmware would solve the issue, but unfortunately it hasn’t.I was going to hide it behind the media unit, but it has to be easily accessible to pull the power cable out and straight back in. It’s not enough of a problem to send it back to replace as others have reported the same problem.Fingers crossed the manufacturer sorts this out in future updates.

My modern-ish TV does not support eARC fully - i use a Sonos Beam Gen 2 (with sub and surrounds) - and it often got inconsistent Atmos across services/players - it wouldn't work with my Sony 4K player. This product resolved this issue for me. Perfect and consistent Atmos support across everything I need.Only downside for me is the annoyingly bright blue LED lights - resolved by black tape so not a massive problem.

Does exactly as I wanted. Excellent so far.The problem I had was a Samsung Neo tv that didn’t process DTS audio (writing off my Blu-ray and PC movies) and a Sonos Arc with only one eArc input and no additional hdmi pass through ports.Problem solved. Pretty much a plug and play set up and now I have 5.1 DTS as well as Atmos from my surround sound system.The infra red extension lead means I have the box with all the accompanying cables behind the tv - a nice bonus point.Note. I needed an eArc converter to feed the tv audio into the switch. All in all an expensive solution for a Samsung cost saving!
