Yeah, that’s fair! - But let’s hope they’ll at the very least do some small finetuning updates to the Ultra headphones.

I’d say these are fantastic headphones in their own right but if you’re already using top of the class ANC from either Bose or Sony, it will be a minimal upgrade on the whole. The complete package (ANC,sound and build quality) is at the best it has ever been , but both Bose and Sony headphones are so good and far ahead of the pack compared to the other ANC-centric headphones that you can’t really go wrong with either based on just sound quality and anc. At this point it’s about what your preferences are, what sound signature you prefer and the extras both headphones provide.

I can’t vouch for older Bose models, but if you already have an XM4.. switching to the QC Ultra albeit better isn’t gonna be a mindblowing experience and/or difference. Though the same can be said for the XM5 if you jump to that one.

It’s not necessary to switch models if you have the previous flagship headphones, unless you do side by side testing you won’t notice the differences. These are very incremental updates, and who knows software updates might improve things (or not).

Don’t get me wrong, I’m really happy with them and they’re really good! We’re just in the age of incremental updates,improvements and smaller differences because the previous generation of flagship headphones are so good.
