Thanks. They look like they’d work for me nicely.They are custom moulded plugs with a speaker in them, then the connect via a 3.5mm audio plug.
Here's a link to the ones I use, sure someone must sell them on your side of the pond. Motorcycle Custom Ear Plug with Speaker | SoundEar
^ This is a good point for ease of install and to ensure it's locked in place and won't fall out while riding. I've never had mine break but did notice that it's easier to seat when you pull up on the front tab first as mentioned above, so:Just a word of warning about the Cardo. I had the same unit and used it without problem on several helmets.
However when refitting the unit one day in a hurry I pressed down too hard to get it to click in to place on the stick-on mount and damaged the lip on the back.
After that it would not stay in place on any of my helmets and I had to get another.
The thing to do if it doesn't click in easily is to slightly lift the release tab while pressing down.
Helmets have different amounts of curvature which affects the stick-on type mounts and thus how flat they sit.
If they plug right in as a replacement to the included speakers, I might be looking at these sooner than later - be nice to drown out some wind/road noise. Cool!Yes you can take calls. I plug them directly in to my Cardo Scala. Normally have the volume on the Cardo down at minimum with auto gain enabled
Exactly what I went with (the 2 pack as well) per my above post. Installed and tested. Audio seems really good... Have to wait for the snow to melt and the new ride to arrive at the dealer before I can really try them (with road/engine noise), but so far impressed. Your comment does add some reassurance to this though... Cheers!Cardo Freetalk 4+ is what my buddy and I use. Can go about .5-.75 miles apart and still good connectivity. The JBL headphone speakers sound great and it is easy to use. Voice commands if you prefer it(I don't use it). Voice comes in clear and can't hear any wind while talking. Just my 2 cents. I'd do a 2 pack if you can find it as it is cheaper than buying single.
