iFi 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.

This is a great product! Picture quality and sound is greatly improved. Use it with the other Ifi filters (lan) and (mains) for even better results.

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

Vendor was fine, product in good condition. This did not solve my issue. Quite expensive for a solution fail. But not the vendor's fault.

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

Cant notice any difference, but it was cheap enough that on the off chance it does something, its worth it i gurss.

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!

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.
