- HDMI iSilencer - HDMI Noise Filter with Surge Protection - Active Noise Cancellation - Jitter Elimination - Supports Ultra HD HDR 8K/60Hz & 4K/120Hz

The improvement in picture quality is very small. I tried the TV, TV box, PS5, and Monitor. Basically, I can see the difference is the computer monitor ONLY, which I think is about 1-2%. However, the effect is more noticeable when used with an amplifier, with an improvement of at least 5% in the soundstage, depth, and clarity. The result is similar to upgrading the speaker cable. Highly recommended if you are in an amplifier or music streamer.

It works as intended, did make picture crystal clear as stated. Audio became more clear and blacker blacks. Have only used for 2 hours, I will update if I find any faults. So far though it's a great accessory to have

Good product but did not resolve my hum issue.

Didn't really work to get rid of the pc noise (ground loop) out of my amp. Connected between pc and avr.

Set up: roku ultra, Audioquest Forest Green ether cable/ iFi LAN iSilencer to Roku Ultra. To me it sounded much taller and wider when using planar type speakers. Images tends to be more natural like, cleaner due to much "darker" background. Month after: plugged this bad boy between CD transport and Roku stick to HDMI extractor converter to opticle output. Shiit Bifrost DAC/ Lyr+ HP amp set up combo was extraordinary, I must say,.. ..especially litening through Audio-Technica ATH-M50,.. full immersion experience to another level!

Excellent sound, very clean and dynamic at the same time, with a natural fluidity that lets you hear nuances that you didn't even know were there, but apparently they were there. I bought this out of apathy and disbelief, to find out first hand that it is essential if you are an audiophile, seriously, it is seeing how purity takes you to another parallel dimension of what you had been listening to previously, reviewing my musical repertoire with this filter is like listening to a modern version of details from my collection, you really won't regret it,exceeded my expectations, I plan to buy others and I highly recommend it.

I host karaoke and one venue has noisy electricity. I have got most of it sorted out but as soon as I plug their hdmi into my splitter there has been a terrible noise to the point I’ve had to bring in my own smaller tv. I plugged this little unit into my laptop and presto, the problem was gone using their hdmi and tv. I tried 3 different 60 cycle hum power strips and power supplies. Nothing got rid of the noise until I tried this last night. I couldn’t be happier!

One of the best investments that I have recently made for my system, the Blacks are deeper and depth and sound are deeper and more atmospheric for sound and visual quality. Totally worth looking into to add to your AppleTV and 4K Player. You will not regret this purchase.

This works! I was doubtful, there are a lot of snake oil filters and connectors out there but this is not one of them. Connected it to the Apple TV end and my darks are visibly darker, colors are richer and audio is more relaxed as well as detailed. Adding this is an upgrade to my AV experience at a very reasonable price.

El dispositivo hace lo que dice en sus especificaciones. En mi caso es más notoria la mejora en audio.

Super

It's best to add it at the hdmi end going into your AVR, that way it allows the Silencer to work best as it works on the data coming through the cable. Hard to determine in real terms what it does because you install it and forget about it. It's certainly not doing any harm.

High quality high performance hi fi equipment. Solid performance improvement.
