Hmm, if only using TWS earbuds for 2 hours a day, that means you may be sensitive to certain frequencies. Try using a sine sweep to find out which frequencies are those and then (parametric) EQ them down.

I use TWS earbuds/adapters or Bluetooth headphones for like more than half the day (basically every week) at lowest volumes and never really get intensified ringing with tinnitus. And like my tinnitus is real bad sometimes, so that's why I always listen at lowest possible volumes.

Wait, don't forget to Disable Absolute Volume in the Developer Options of the (Android) phone. This will let you have more volume variation, particularly useful for achieving lowest volumes possible.

More Bluetooth stuff like disabling Absolute Volume for reducing volume and static/et cetera: https://www.reddit.com/r/headphones/comments/10iu22p/static_noise_in_the_background/j5ibwms/

Make sure you have the vacuum seal so that you're not raising the volume to compete against the external noises. You may need to switch to aftermarket ear tips if the current stock ones do not work well with you, see below threads for more info.

This is how you should use Etymotics or really any IEM or TWS earbud to make sure you have that good/perfect fit for that vacuum seal (necessary for the bass to be properly produced): https://www.youtube.com/watch?v=8KwXEqe6Gq4

Try parametric EQ for more sound changes.
