Viborg 2X Male XLR Dust Caps Gold-Plated PTFE Insulated Noise-Reducing Protective Covers

Quality product and it fit's well. Highly recommend.

I was not expecting any audible difference from the employment of these XLR noise reducing caps, having instead bought them for the dust-cover they provide. Imagine my surprise when they produced an immediate and clearly discernible improvement in low-level detail retrieval, dynamics, air, focus, and sound staging. Simply remarkable! Highly recommended for people with very advanced audio systems where these type of subtle improvements will really come to the fore. Give them a try. You might find, as I did, they really do lower noise and improve sound, and all for a very, very reasonable price! Happy Listening! Winston Smith

Well made caps that fit perfectly on my headphone amp. I swear that the noise flor on my headphones is a little lower but that may just be in my head. These are quality made and solid, good stuff.

I purchased these to block off some outputs that are currently unused, in order to assure musicians didn’t inadvertently plug into the wrong channels. They are not only solidly built, but are easily visible and completely obscure the connector so that it is clear “you don’t plug into here!” Since adding them, the problem has disappeared.

I am using these both to seal off unused outputs and to prevent noise. They fit well on the balanced outputs I put them on and complete the look. They may or may not help with interference prevention. Hart to tell.

Great quality!

Love it for keeping dust out and simplifying rear connections on my preamp when I need to disconnect and reconnect things
