get a pair of Sennheiser HDB630s @douglas_schroeder 

Depends also on your music taste. Loved the very detailed AKG noise cancelling headphones, but replaced them by the more sturdy Sony ones. Traveled with these all over the world for many years. If you like rock music then Bose is a good choice too.

The noise canceling Sony's have served me very well the last few years although I only use them when traveling and on flights and watching movies, not really music. Very durable so far for last 3 years or so.

@douglas_schroeder Other options welcome. 

wireless earbuds? If so, I have an older Hifiman and Noble Pro wireless earbuds. I also purchased Technics EAH-AZ100-S(Silver) last year 2025. My Noble Pro sounds best for music. Maybe check out Noble’s current offerings here

Also, I agree that better engineering and parts in more expensive components typically outperform lower priced components. But some Agoners can be touchy about advocating this due to limited budgets. 

I asked Bose how much better is the noise cancellation on the newer Quiet Comfort Ultra Gen 2 than the older Quiet Comfort 45. I own the ’45s. The most quantitative answer they could offer was "better".

I bought the Gen 2 anyway. My next door neighbor was having their concrete driveway replaced, which is a VERY noisy project. And perfect to compare the two ’phones for noise cancelation. The Gen 2 is obviously better for this, which is important to me because I mostly use these on airplanes to reduce the 90+ dB ambient noise level.
