As someone who does a lot of air travel on company planes and commercial, a must-have on every trip are my Bose QuietComfort headphones. They cut engine noise by half or better, but they are terrible for sound quality if listening to music. They are passable for hands-free phone calls though. I’m not about to start travelling with two sets of headphones though - gotta draw a line somewhere.
Best earphone for the value

I bought the earphone after reading rave review on it.
SoundMagic E11C review | What Hi-Fi?
The review is spot on.
The most remarkable difference between this and free earphone distributed by Delta Airline is detailed treble.
I also compared this with Grado SR80E headphone that I have.
Grado have slightly more open bass but this one seems to have more details.
Due to the limitation of luggage, I would rather bring earphone than regular headphone for long travel.
This one fit my need at the cost of 60$.
I found that the music through Youtube or Amazon prime using SoundMAGIC E11C earphones is quite enjoyable.
I highly recommend this for travel.
