> spent some money on a noise cancelling headphone
Which one? I also facing a noise issue with some people that move closer, and getting crazy...
They have blessed me with some blissful naps, however. Possibly their greatest superpower is making robot vacuums disappear.
Finally I realized that I need NC for removing some fan noise like HVAC and server but I don't need superior one. I got Beoplay H9i for $300 and satisfied for both. Fewer battery life is cons.
