Official wind noice service bulletin
I would suggest though "no wind noise at all" is probably unreasonable, but unless you have someone who has driven a 'non-noise' version versus one which is noisy, there's no way to really know. I don't think you can compare it to laminate glass since that will naturally be quieter in any case.
What's normal?.. probably impossible to quantify or answer. Given that MB has acknowledged there's a problem though, it should just come down to what the customer considers acceptable or normal.
My car is coming up for it's first year service and I'll be raising the very same question with my dealer. I wouldn't consider mine as bad as what's been described in some of the posts here, but for me it's still noisier than other cars I've owned. This whole issue and its potential resolution has probably more to do with how much noise the customer makes rather than the wind acting on the car and the willingness of the individual dealer to keep the customer happy.
This was the first time I was certain that I had the wind noise problem discussed here. My 2007 W203 had never been completely silent. Installation of acoustic glass reduced the noise to about the level of the W203. Even before the replacement, my wife and I made an 800-mile round-trip (mostly on interstates) at 70-75 mph, and the noise didn't bother me. My wife really doesn't care for the radio, so when I drive with my wife, I don't play the radio much either (let alone, play it loud). So I can live with the present noise level until MBUSA comes up with better seals. Others have also commented that luxury cars like BMWs and Lexuses are all quiet as vaults. So the problem is still a black mark for Mercedes.

Hate to see that it still hit Jan 2016 builts. At this point, I think I'm going for May build and wonder if it will be all sorted out by then.
Hmm strange. I'll check other 3 windows and report. Mine is March 2015 built.
Anyone else like me?

Drove a 2016 loaner car and it did not have acoustic glass, but noticeably less wind noise.

Also getting a Nav update. I'll be interested to see what version is installed.
- Firstly, good luck aiming to get the replacement for free (or under warranty) unless you're driving the C63S (that's according to the conversation I had with my dealer; apparently because parts availability is too tight)
- Price: AUD$607 (inc. GST) for the pair, plus fitting.
