I also sell XLR caps in a separate listing, this is 4 the 4 jack inputs on the MS101JackCaps come in two styles, Studio and Gig Ready, Studio JackCaps will work great in a studio setting, easy to fit and strong enough to remain in place even when turned upside down, 

Gig Ready were introduced in late 2019, they offer an increased grip and closer fitting making them much more adapted to gigging life where instruments are constantly moved around and the great thing is that they only cost just a few pence more.

The original advert for the JackCap jack and XLR advert, 

 Welcome to the Home of Jack Cap, The Musicians Friend  Jack Cap is a Dust Protector for your unused 6.3mm Jack and XLR inputs  I am a musician myself playing Keyboards in a Rock Band, my equipment means everything to me, I gig live with the Nord Stage 2 and the Korg M3, using the Jack Cap means that not only am I protecting the Inputs that are not used but it also speeds up the setting up time for me and alleviates the problems of making mistakes putting cables into the wrong holes when i'm on a darkened stage,  The Korg M3 for instance has 12 jack inputs on the rear and i only use two of them when gigging. They are all very close to each other and look identical apart from the small text above them, I use only two out of twelve Jack inputs so I have 10 Black JackCaps permanently pushed into the unused inputs giving total protection to them and I have two Bright Yellow JackCaps in two remaining inputs open so when i am setting up I know exactly which two inputs are used,   Unlike other products on the Market the Jack Cap is designed small enough so that they can remain on the keyboards when they are packed away into their Flight Cases without Causing any obstruction Problems. Jack Cap is Available in a Selection of Pack Sizes, They are made from Soft Silicone ensuring a perfect fit, they are easy to attach and remove and being such a snug fit they will not fall out even if your equipment is turned upside down, Other similar products are made using hard sticky out plastic plugs, these can get knocked more easily as they stick out and cause more damage because they are hard plastic, Jack Caps are slimmer and soft so they protect your equipment much more than the competition and they are far cheaper to buy too.Now Available in Three Colours, Subdued Black, Standard Red and Bright Yellow, Now Available in Two Sizes, 6.3MM Jack Input and XLR input,   The Tapered Design Ensures a Tight Fit meaning it will not Fall Out even if turned on its side or upside down, great for packing away your equipment into flight cases without worrying about losing them,

The Soft Silicone Rubber creates a Tight Protective Shield and acts as a soft crumple zone incase someone does knock into them.
