I've looked everywhere for circular autocom speakers. I have a set of oval ones which don't fit in my shoei Neotech too well and put pressure on my ears. Are there any alternatives out there ?
I find mine is OK with the oval Autocom cases, I mounted them in at a slight angle with the speaker bit in the hole and the other end of the case slightly out of it, pointing towards the top of the helmet.
I then peeled the foam backing off the back of the blanks that cover the speaker holes when no speakers are fitted, cleaned the glue off them with Isoclene (isopropanol), and refitted them over the speakers. Very comfy (well it is with my likkle ears )
Edit, I forgot to say, then wash the covers to get rid of the isopropanol residue
