It depends on your tinnitus itself. My tinnitus gets crowded out by a loud environment, I don't tend to hear it. I only hear my tinnitus when there's no sound. So for me, noise-cancelling headphones do give some temporary symptom relief.
Wearing a Bose QC 35 is so important for me when I go to sleep, because the ANC also blocks out sound and blocks out my tinnitus to some extend. It's a bit of a skill to sleep with them (you can get audio feedback of the ANC mics) but I've mastered it and improved my sleep game a lot because of it.
Bose recently retired their 2nd attempt. The team behind those have a new one coming out in January, https://ozlosleep.com I'm pretty interested... hard to tell how long the pre-sale discount lasts
It doesn't seem to have ANC, so it doesn't noise cancel, it only masks. And if ANC is the same as masking then they'd need to put that in their marketing.
Also: yep, that's what I mean by it, the white noise sound.
