Cayin Headphone Jack Dust Plug

These plug covers for 3.5mm and 4.4mm audio jacks are a good investment for protecting your hifi gear. The 3.5mm plug is definitely ideal for protecting a toslink digital input/output and it will block the red LED light coming from within. The only downside I’ve experienced with these is that the 3.5mm plug doesn’t seem to be quite large enough to fit snugly into my 3.5mm to 6.35mm screw on adapter. That one issue aside they work perfectly with everything else! I also love that they come inside of a velvet covered and lined ring box with a slot for each of them. If you’re looking to protect your investment like I was then you can’t go wrong with these… 😁

Cayin Headphone Jack Dust Plug

Works as intended. Keeps the dust out of my Hiby R4.

Best dust plugs ever used. They stay in perfect on my RS8, which isn't a Cayin dap. A must item to have.

Just love it it’s on top of being efficient it is beautiful and matches very well with the volume and forward / backward buttons
