The only issue I have with it is that pairing can occasionally take a minute or two, because I have to pair with a different device sometimes and it remembers the last connection first.
However, other than that, they work fantastically. The noise cancellation is on point, the battery lasts for ~8 hours or so, and I have been a very happy camper since getting it.
Recently compared it to my girlfriend's QC25, and I really enjoy having the convenience of not having to pop in a battery and no wires.
