1. Noise cancellation works best for consistent noises
2. Noise cancellation doesn't really work for high frequencies (in headphones, at least)

Your best bet is just to get some closed-back headphones with good noise isolation, like the:
* Sennheiser HD280 Pros
* Beyerdynamic DT770 Pros.
One thing I would recommend is getting an aftermarket set of earpads, as they're far more comfortable and they do a better job of sound isolation. I just got some pads by Brainwavz because the originals wore out, but I wish I'd done it a while ago because of how much better the isolation is.
it works decently well for the low and some mid frequencies. It helps.
Probably your best bet is headphones or earphones with both noise-cancelling and good noise-isolation.
Airplanes are an easy problem to solve for because the engine noise is loud and of a constant tone.
The problem I need to solve for is random noises found in the workplace like people talking, printers printing, and other inconsistent tones that’s happen throughout the day.
Has anyone found a good pair of noise cancelling headphones that work in an office environment?
