They are an "add-on". I've had them for a while - they came with a walkie-talkie based intercom that was a fixxer (the speakers weren't).

I also have tried a set of these (still got 'em): TORKX2 - Tork X2 Helmet Speakers. I went back to my old one's as the cord is thicker with a good waterproof plug whereas the Torkx seem to pick up some wind noise.

Just got some custom made plugs from EARMOULD in Adelaide. Fantastic! No more roll ups falling out of my ears and much quieter and more relaxing to ride with. Just be aware that for the first couple of days 110k/hr feels like 80k/hr. cost was $70 fitted on the spot and you walk out with them in 30 minutes. Can be fitted with earphones for iPod as well but I don't want that distraction when riding and certainly don't want to answer a phone. Highly recommend these plugs and this company.

I've been a fairly regular wearer of ear plugs and normally use the orange or yellow foam cylinders. I've never had an issue with them coming out, etc. But I did drink the koolaid one year at the IMS show and had customer plugs made and they were a problem.

Once I put on my helmet, yawned, smiled or pretty much anything that involved facial muscles, the "seal" would break and I'd have all the noise back like an on/off switch from hell. Distracting, annoying and in to the garbage they went.

My foam plugs have never done that over the past dozen or so years I've used them.

When doing custom ear molds, keep your mouth relaxed like you would normally have it while riding. Yawning or clenching your teeth can break the seal momentarily but it will return.

Possibly the material they used? My first pair were of a quite firm material and did not fit as well as my newer ones which are much softer. The newer ones stay in a lot better and are a lot more comfortable to wear for extended periods.

I use foam plugs. I also have a sena blue tooth with speakers. You can install the BT in any helment. Works well. I can knock the wind noise down and hear the speaks clear. I wish they could go just a tad louder, but I can still hear them. On the interstate its a bit hard, but on the back roads no issues as I try not to ride on the interstate.

I have in helmet speakers for my communication gear and music and almost always wear foam ear plugs (whatever brand we have at work). I find it most important to wear them when listening to music because otherwise you are not only listening to road and wind noise but overcoming that with even louder music. I find the ear plugs cut out the road and wind noise easily and make the music much more enjoyable when I don't worry about destroying my hearing.
