Sharing the simple DIY to create a speaker pocket in my C70:

First, gone hunting for cookie cutter. Found one set of 12 pieces, and has a 42mm cutter. Bought it from Shopee. I press the cookie cutter into the foam to make a mark.



Here's a nice circle created by cold press the cookie cutter.
I further heat up the cookie cutter with a heat gun, then press the heated cutter further down for the depth I wanted.
A heated cookie cutter will melt through the foam.



Irrigating is a little challenging.
With the cooking cutter in place as fencing,
I use a combination of soldering iron to melt down the foam, and a steel ruler to excavate and flatten the surface as much as possible.



Test placement of the speaker.
At this depth, the speaker is only half buried in the speaker pocket I just created.
Even so, it's poking on my head.
I deepened the pocket further afterwards, and have the speaker fully buried and flush with the surface.



Another view of the speaker sitting nicely in the pocket without needing any velcro to hold it in place.
Later, I use soldering iron to cut out a cable trunk to run the speaker cable out from the pocket.

My buddy had just bought and installed his bluetooth headset in CS-15, stock standard speaker pocket, no need to mod like my C70.

You ask just in time.

Friend with CS-15 tested with ear bud + bluetooth speakers installed.
No issue.

Why both you might ask.

Because cheapo bluetooth speaker set does not mix in navigation alert when you are on intercom.

He was running intercom with his wife but need navigation alert, hence both devices running at same time.

Cheap solution, for RM200 bluetooth + Rm100 ear bud.

Jealous with you fellas can have to many option for helmet.
I tried Zeus and my head can't fit it's sizes ..
no cheap daily trash helmet for me.

Sad....

Not buying anymore helmets.

I now have 4 sitting around. Latest is a Shoei GT Air 2, going full face after trying out HJC C70 full face and find myself can accept full face.

So how have JCruise2, GTAir2, C70 and one XDot half helmet.

Daily beater will be the XDot and Jcruise2.

Might change the padding in C70 to one size smaller, use it for carrying suicharboh pillion if I happen to meet some during my ride 🤪

How do you all store your helmetS at home?

Hang on wall?
Lie flat on somewhere?

Try Shoei.

For your budget range you can try HJC CS-15 which also fits my wider head pretty well when those brand you mentioned failed even with their XXL.

First point, measuring circumference is super general as shape of head is more important factor.

Secondly, most helmet manufacturers make only two shell sizes and use different thickness padding to create different size.

You can go to helmet shops that does custom fitting. One of them is HJC, the other Shoei.

HJC has budget friendly range.

For HKC, You can go WeBikeToday, they have showroom at KTM showroom Old Klang Road

How do you mount the cam? I know I can google about it but .....

I never bothered about those custom built comm system like those designed by Shoei or HJC, and they partner with Cardo / Sena. Only thing good about them is they are flushed within the helmet.

I just stick the comms outside.


For helmet cam, I had been procrastinating on getting one.

Why would you want to mount Insta360 at helmet chin?
Ain't that kinda wasteful for a 360 camera?
