I got a Sena 20S Evo and installed it in the helmet.  The sound quality is adequate, but there remains the wind noise...especially if going over 40.
 
I used to use earbuds to listen to music, with the earbud serving as both hearing protection and speaker.  Since Sena doesn’t make a Sena-to-headphone jack adapter (letting you remove the helmet speakers and use the shielded audio port to plug in), I see two basic options:
 
1.  Use hearing protection adequate to prevent hearing damage without seriously compromising sound quality.
2.  Modify the helmet to better block out wind noise.
 
I haven’t picked out a new helmet yet, and there’s no guarantee that what I buy will do the job in this area even if it’s better than what I have now.
 
I tested with Quiet Contour foam ear plugs (WalMart).  Noise reduction rating (NRR) of 33 dB.  Definitely protects but sound is muffled while testing indoors.
 
I then tested Plugfones Guardian In-Ear Earplug Earbud Hybrid - Noise Reduction In-Ear Headphones I got from Amazon (https://www.amazon.com/gp/product/B00RW1R81E/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1).  Removing the rubber tips and using them (have hole where earbud is attached, music quality was good, but no idea how much hearing protection it provides.

I could try better suited earplugs, but I don’t know what to look for.
 
Examining the helmet, the cheek pads have nothing directly over my ear canals...I question if I could install padding here to block wind noise (see photo).

But ... but ... but you're supposed to use crappy bluetooth stereo for everything.

I have a 20s on a fairly noisy Arai. When only listening to BT music, speakers with foam ear plugs work well at legal speeds. When listening to music and any other input(zumo and/or intercom) I use molded in ear that I got at the big motorcycle show. I haven't figured out how to mix the different inputs effectively. And yes, with the in ears plugged in waterproofing is gone so I live with one input depending on the situation.

I have used foam ear plugs and a Sena for years and never had a problem.

Oh, I know testing indoors is weak sauce, but it’s good for seeing how different options compare.  My standard foam plugs deaden too much.  If I find something I like, then I’ll see if it works as well when riding.

Same here. ( Hear? )
I just turn up the volume a bit.

Remember that hearing damage is cumulative, too. What might not sound like a lot of noise infiltration today could be tomorrow's tinnitus.

Just FYI: The hair cells in your inner ear don't care whether the acoustic energy they receive is music or wind noise. Prolonged exposure to either at sufficient amplitudes will damage them. WBill

Yup.

Well, I just got a chance to try out the EarPeace ear plugs.  Went with the lowest reduction.  Not bad.  Too bad the Sena speakers are pure ass.  Windy day, so it was a good day to test.  I suppose for all day rides I’ll have to stick to earbuds as I had the Sena at max and could barely hear (although music was not all that “muffled” with the plugs), and at max volume, the speakers are particularly bad.  These work well for short jaunts where fiddling with wires is undesirable.  That’s my big issue...earbuds involve fiddling with wire placement so they don’t get caught in zippers, pinched or you turn your head and it pulls an earbud out of place.
