I have some QC25 headphones I bought in 2015 and they're still working well, other than having to replace the cushions a few times. No "smart" features, just a regular cable to plug them in. Noise canceling works well and I use it whenever I'm flying somewhere. They take AA batteries which is way more convenient than a built-in battery. I use Eneloops, and once the batteries don't hold a charge well any more, I can just get new ones.
