I'll weigh in here... I have had all three (BV2S, MOD3, and just bought the Oxygen).
I was in Sudbury two weekends ago for my first ride with the Oxygen. My first impressions were very good:
It's light
Huge field of view
Very quiet, shockingly quiet actually
It has built-in sound canceling earmuffs (they are velcro removable) which contributes to the quietness
Highly usable with coms because of no mouth piece - mic is not muffled, and those sound cancelling earmuffs have foam cut-outs which you can install speakers inside of
The magnetic cable connector is awesome compared to RCA connectors, and although I thought the inline visor remote control was gimmicky - the green light on it which indicates connectivity is awesome as I have had countless rides where I'm wondering if the shield is even being powered
The sun visor is actually usable and resists fogging quite well.
The rear light (I'm told) is great too for visibility behind you - and it's not battery powered
It was very cold in Sudbury and blue sky sunny during the days we were there, so I got a good feel for the helmet. BRP has clearly put some solid engineering and thought into this thing.
With all of that said though... on Day 2 there was condensation that had built up in between the two layers of the shield overnight. After riding all day with the heated shield on full, and the sun beating down on it, the condensation or some kind of streaking from it was still there and impossible to clean. It covered the entire shield and didn't block me from using it, but it did reduce visibility by about 30% which was annoying, especially considering the price. I took it back to The Cove in Muskoka where I bought it and they contacted BRP. They have apparently issued a service bulletin about it and they sent out a replacement shield. Hopefully the replacement shield solves the problem because I love the helmet. I'll report back next weekend after I get to try it out again.
