To reduce the amount of RF interference entering your system we recommend "capping" all unused USB Ports.

AudioQuest USB Input / Output Noise-Stopper Caps (Set of 4)

 

In a world immersed in RF/EMI interference we all need the sound of silence... Nothing makes an audio/video system more irritable than RF interference- the bane of dynamics and clarity. To reduce the amount of RF interference entering your system we recommend "capping" all unused USB ports. You'll be pleasantly rewarded with a blacker background, deeper sound stage, and a richer more satisfying overall experience. 

Blocks a significant path for incoming high-frequency energy to interfere with circuit performance.

 

About AudioQuest

AudioQuest has been the largest cable supplier to the high-end specialist market for many years. AudioQuest is sold in several hundred outlets in the US and in over sixty countries. Bill Lowe (Founder) is especially pleased that this success has been possible despite his insistence that the foundation of the company, and the foundation of AudioQuest marketing, must be the performance of the product. In the audio world, many professionals have learned that it is not always convenient to listen to the products they sell … they might learn something they don’t want to know! Bill has always understood the challenge of basing the existence of AudioQuest on the performance of the product. However, to Bill, this is the only reasonable way to do business and the only acceptable way to combine his passion for music (and all things high performance), with his need to make a living.

Disappointing!!
25 Mar 2024
Verified Buyer
I've tried these for a week, but sadly, I don't hear or see any real influence on any of my HE equipment!

They fit well in the sockets and look nice, but they're a bit disappointing. I would say that, at best, on my equipment, the effect is marginal and, at worst, non-existent.

Pricey dust caps for me, I'm afraid!!

Sorry!!

These do exactly as advertised, deeper and wider sound stage, and better instrument separation.

A very well-made product which fits solidly in my USB ports
28 Aug 2020
Verified Buyer
Having freed-up several USB ports on my PC after investing in a powered USB hub to connect all my various devices (webcam, printer, etc).

I decided to invest in a set of these AudioQuest stopper caps, as part of a range of efforts to reduce interference/noise/ringing that has sometimes plagued the many 'Zoom' video conference calls I'm currently undertaking.

It's difficult to say precisely what impact these caps have had, because I also implemented various other upgrades at the same time (including a new Tacima mains conditioner extension-lead and also upgraded USB cables), but the sound certainly has improved overall. The stopper caps are very well made out of metal, feel very solid and fit very well in the USB ports,

ENGLISH TRANSLATION: After applying these small isolation caps to the HDMI and USB ports on my TV, I found that both are really effective in producing an improvement in the overall image quality in contrast and definition.
I recommend
