Silicone earplugs also work well. Or, if your train has one, go in the quiet carriage.
Imagine you had a 30 minute commute. What would you do with the extra 90 minutes? Watch Netflix? Play Zelda? Meditate? You can do all those things on a train.
Yeah... I am not sure if the investment is worth it into the headphones. I'll think it through.
Honestly, that's a really question. I'd probably watch YouTube, think about the state of my life and do some other similar... Stuff. So I guess really not much different, but my mind cannot relax in a train. Plus I have to drive at the end of my commute through very rural roads, and it's absolutely the worst part of it all.
Honestly aiming for sleep is probably the best thing for the short term. Trying to learn new skills or look for a new job/apartment while exhausted and stressed just compounds it.
Best of luck. It will get better.
