I've been seeking this product for a couple of years to use with my guitar amplifiers so I can block / plug the unnused 1/4" I/O jacks. Not specifically to keep dust / dirt out, but to keep me from fumbling around trying to find the correct jack to plug into on a dark stage. So I install these in the FX send / return jacks, the preamp in / out jacks, and the unused speaker jacks on the rear of my amp heads. Now there's literally only a single speaker out jack open and I can just plug right into the speaker out and know I've got the right connection.I have not personally done testing to see if these will truly seal older 1/4" jacks found in speaker cabinets. Those older jacks aren't sealed and leak air and can whistle when used in bass cabinets which have a lot of air displacement. But I suspect these would work well enough for that application, too. In fact, that's where I first discovered these products - installed on a Mesa Boogie bass cabinet.Cons: It's a box of 100 which I'll never, ever use, and probably a little expensive for what the product is.Pros: They make great gifts for all of your musician buddies who will marvel at how clever you are.

If you are looking for plugs to seal 1/4 inch instrument jacks (like on any Guitar/Bass amplifier), than this is the one for you. The fit PERFECTLY. They "snap" in nice and tight, but with a little prying come out if desired. Wish I had found these years ago as they are VERY helpful in preventing debris and dust from getting into the rear jacks of my rackmount units and amplifiers. 10/10.

Replaced all 4 on my enclosed trailers Dexter axles. Rubber feels more durable than OEM's.Should easily stand up to the test of time.I would recommend.

This is perfect for any musician or sound engineer, to keep dust and dirt out of 1/4" jacks. Affordable, dead simple, hard to screw this up.

Great product

I expected them to be rubber, but they are a harder plastic. Would not do a good job sealing out water.

These were shipped on time and priced right. They are a little more light weight than I am used to having but they do the job.

I have only had these for a few weeks, but so far I am very pleased. I had a safety cover installed on our pool and used these to plug the hole in the retaining screw to keeps and and other debris out of the holes. I intended to keep the plugs in over the winter months and will reassess them in the spring.

Not impressed the items look so much bigger in the photos then they actually are. Also I see now no return option so a waste of money for sure.
