Helmet earplugs&headphones - Sennheiser IE200 recommendation

For some time now I've been looking at a good motorcycle earplugs/headphones combo, looking at reviews and other recommendations but none really fit the bill.
Given that the stage performers also need noise cancellation but also clear feedback as to how they're playing idea came to check out the "audiophile" spectrum as I figured they would know this stuff, came across the Sennheiser IE line in-ear monitors.

Settled for the IE200 and after a few thousand km I can say they're excellent! Pricey at around 160 EUR but very much worth it so far.

I went for wired as anything wireless is bound to dislodge when putting on/off the helmet.

IE200s have an extremely low profile and I'm yet to snag them when taking of the helmet, wiring goes around the back of your ear (very thin, not noticeable=, USB C adapter (they are 3.5mm by default) into phone for music/nav. Had them in for 3-4 hours at the time with no discomfort.
On the plus side they go in the ear and act as an earplug in the 25-30dB range and don't depend on active noise cancelling.

Stock RS screen, 90mph I have a podcast or music around 40% volume on my phone with excellent clarity, previously the AKG/Samsung headphones I had was around 80% with podcasts being harder to hear.

The wind is muffled (if that's the right term, 'quieted down') as is road noise such as rumbling truck engines or car tire noise on the highway in adjacent line. You can still clearly hear things like sirens or horns, voices are also OK as long as the toll booth operators raises their voice a bit :)
They don't have a mic which I don't mind as I'll just pull over for phonecalls and nothing flapping in the wind below my chin.

I have IE215s which I assume are either older or similar model. It never occurred to me to use them under my helmet but they have been great for the three years I've used them in the gym with my Ipod. I expect they do a nice job reducing noise around you because they do a good job in the gym of reducing the noise of peoples feet hitting the treadmill. As far as comfort, I don't really know they're in unless the cord catches on a piece of equipment.

I believe those are an older model, but definitely give them a try if you listen to music while riding the sound dampening and clear music is excellent for long highway stints

I've never listened to music while riding. I bet it's nice, as you say, on long rides. Those in ear monitors fit snugly but not too tight. I can see they would slip right under your helmet. I'll have to try it next time I go out for an extended ride.
