They work well if you are not moving around, otherwise the seal breaks and you must adjust them. This is no good if you wear them inside a motorcycle helmet or your hands are in use. When they are in they are comfortable and effective.

Do a good thing for the environment and don't throw out after single use, as these plugs can be washed with soapy water to become new again!

Good product, use it for my violin practice. Got a pack of 10 and been using ONLY one pair for 2 weeks 👌🏽

If like me you have trouble using foam earbuds then give teh Skull Screws a try.

In my opinion there are none better.

Berry good
