Hi Sherri,
I would like the noise cancelling headphones, not to listen to music, but to block out all noise, so I can concentrate and study, and to tune out background noise while at work. My question is, re this headphones, must I listen to music/audio in-order to tune out all noise? If I do not want to hear any sound - including music - is that possible ? or the headphones silence works only to tune out noise while listening to audio?
Also, which one is the best re no noise AND no white noise OR hiss?
Thanks in advance.
I use noise cancellation in the same scenarios as you are looking for help in (blocking noise while working or concentrating on studies).
TL;DR: Bose QC35s work best for me. They're comfortable enough for all-day use, and have about the same noise cancellation as the best from Sony. I noticed a very slight hiss only from the Sonys when there was no music/voice playing.
I used Sony's 1000XM3 for a while, and also tried Bose's QC35, since they had the highest ratings for noise cancellation. What I found was that the Sonys seemed to do a ever-so-slightly better job at noise cancelling, but they just were not comfortable for long-term usage. I've been much happier with the Bose QC35s because I can wear them 10+ hours per day without any pain or discomfort. The headband of the Sonys would slowly begin to hurt after 2-3 hours, and the earcups were not as comfortable, especially the lower part that pressed a little to hard behind my jaws. These may sound like minor issues, but when you wear headphones all day every day to block noise, comfort becomes a big issue.
As for hissing, I don't hear any from the Bose, but I hear a slight hiss from the Sonys. If you get the Bose, be sure to update the firmware on them, because there was an older firmware that had issues with hissing.
