Well it’s a little noisier than my old NEXX X WED 2 was but that wasn’t a flip helmet. The Neotec 3 is also a bit heavier. It’s a better fit and more comfortable and it has the flip bit. That wasn’t a great in the warm weather.
In answer to your question it is slightly noisier but unless one is trying to make a distinction between them then it’s not noticeable.
