You will get hearing loss listening to non NC cans on a jet.
Don’t even consider it.
Airlines give out cheap ones. They don't care about your hearing.
Portable amp for Beyerdynamic T1?
At home, I just use the headphone out on my preamp. Haven't traveled much in the last couple of years, but I'll need to travel a few times for work going forward. Anybody have a rec for an amp for my T1 that's small and light enough that I can take it in my small carry on bag?
