Doesn’t interfere with my crash helmet, much easier to remove the earplugs.

It is baffling that Earpeace thought to make this cable seemingly from the same material as their earplugs. Perfect acoustic coupling! Every tiny movement of the cord is transmitted to your eardrums. It's like wearing a stethoscope.

It doesn't fit in the carry case either so have fun removing and reattaching it every time you want to use your plugs. FYI there are no instructions for how to do this.

To top it off the thing looks super conspicuous (and not in a good way). A gigantic bogey springs to mind.

This may be the single worst product I've ever bought.

I'm actually quite disappointed with this connector cord.
Positives: the silicone does seem sturdy and will last, which is good.
Things that need improving: there are no instructions on how to connect these to your earplugs either online or physically - I did search! As these are small pieces of protective equipment, I don't want to damage the important parts (earplugs) by faffing with an accessory.
When I managed to find a way of connecting them (probably the wrong way), the cord itself conducts sound incredibly well, meaning that when it bumps against your neck, clothes, hair, etc. all that vibrational energy is transmitted directly into your ears, which is at best distracting and at worst painful.

Summary, not worth purchasing unless these are made out of fabric that does not conduct sound.

Really love these! Feels so soft in my ears. They literally melt in my ears and I don’t feel a thing! I’m super sensitive, so these are great. Also work great for blocking out the right amount of sound in concerts etc. I’m so glad I found these! I suffer from aura migraines that can be triggered by loud noises as well, so I’m super happy with these!

This is an OK product. It is fiddly to use and this wouldn't be an issue if the earplug containers were designed to accept the plugs with the cord in place. Alas, not. They expect you to take on earplug out of the cord each time you store it as they won't fit in with the cord in place.

Also, to be honest, this cord probably costs buttons to make and should be included with the product.
