Which tools are enough for a simple pad swap?
Spudger, tweezers, and wipes. A screwdriver only if a screw actually holds a ring. Anything beyond that is for a different job. Split the purchase so a pad swap does not turn into a full repair kit you will not use. A SADES cushion swap stays on this small shelf, and the new pads still have to match that model.
The tool for replacing ear pads on this shelf is plastic. That means replacement ear pads with tools belong here when the job is cushions. You buy plastic spudgers for ear pads, then add tweezers and wipes, before you look at a larger case. A plastic spudger for ear pads, an ear pad replacement tool in the same plastic, ear pads with install tools, and an ear pad replacement kit sized for cushions are the whole simple buy.
On this shelf, plastic spudgers for a simple ear pad swap at home are the start. A headphone repair kit that splits a simple pad swap from a harder repair keeps the extra pieces off this shelf. Use plastic pry tools for ear pads at home with no metal edges as the right edge. An ear pad tool kit for over-ear and on-ear headphones can be this small set. Use wipes to clean the pads before you install a new pair to close the job.
