Are the dimensions listed the recovered or unrecovered size?

Hi, The 4:1 shrink ratio simply means that it recovers to 1/4 of its original diameter. I hope this helps! You can contact us directly if you need more info.

Can it be used with self regulating heat cable

Hi, We do not recommend it because it will generally be kept at a higher temperature, up to 120℃, occasionally as high as 175℃.

Can this be used to cover banana plugs in use with speaker wire?

Thank you for your question. Yes, it can be used to cover banana plugs in use with speaker wire.

Can these be used to reinforce the wire leading to earbuds? The rubber has ripped exposing a small window of the wires.

You could if you are very careful as the heat needed to use for these could very easily melt the wires for your ear buds. You may be better off using liquid tape.
