Evolve2 65

I've recently acquired a set of the new and sparkly Evolve3 85's and I was excited to get going with them. I've got a set of Evolve 2 55's, a set of 65's and two sets of the 75's. I really love these headsets and they fit the bill in every way, apart from they are on-ear and not over ear which is what I really wanted, for comfort. I open the box to the new 85's, get them all connected, make sure they're updated etc and I was instantly unimpressed with the active noise cancelling ability of them. I gave them the benefit of the doubt, with the thinking that maybe it changes based on environments... Nope. I'm currently sat in an office with people talking (not very loudly) roughly 15m away, a radio on, printer going brrrr every now and again, people making tea/coffee, typing, tapping on the table - I hear it ALL. Even while listening to music. I'm not sure if it's just the ones I have that are defective, or whether an update is needed or that's just what this model is like, but these are poor compared to my other Jabra sets. "Find focus literally anywhere with our best ever noise cancellation. **Jabra Advanced ANC™** adapts to your individual fit and surroundings to block distractions for both music and calls – something most headsets can’t do." This is what Jabra have on their website, but so far, I do not believe any of it and actually, it's totally the opposite! Does anyone else have these? If so, how have you gotten on with the ANC functionality?
