I don't know what the other reviews are in reference to when they talk about pairing. These are WIRED earbuds so they do not requiring pairing of any kind. I had the Bose QuietComfort 15 but I really didn't like the design or the way the controls made it fairly heavy and awkward. especially for buds that cost $250! I bought these LASUNEY a year ago when I could've sworn they were $10 more expensive. I put them away for a while to favor Bluetooth wireless earbuds but recently decided to give these another try. To be honest, I've gone through quite a few ANC earbuds in the under $100 bracket, both wired and wireless, and these are definitely one of the better ones. The buds and the cord are lightweight so I don't feel any tension pulling down on my ears. The remote / mic on the cord isn't too high or too low. It comes down to chin level which is just right. Controls are pretty standard. Outside buttons control volume. Middle button does everything else: play, pause, skip, go back, Siri / Alexa, answer & end calls, etc. Overall sound is very evenly balanced. Maybe it could use a touch more bass, but if you like that, you can add it on your phone's EQ. It's also nice that it doesn't change when the noise cancellation is activated. As for the Active Noise Cancelation, it does a solid job with ambient noise like fans and AC though it doesn't completely eliminate it. It helps with general city noise. If you need something more cancelling, virtually nothing short of over the ear headphones will work. It does come with an ambient noise button in case you need to hear something outside what you're listening to like an airplane announcement, though i find in the time fumbling for it that it's just as easy to hit the pause button on the remote. There's also the advantage of it can be used like normal headphones if the battery for the ANC dies which I haven't gotten to which you can't do with wireless earbuds. It's not perfect, but for a ridiculous price of $15, it's a lot of bang for the buck.
