I've had pretty good luck with various Etymotic models. They are durable, more-or-less noise cancelling, sound pretty good (especially for the money). The major problem is that they require deep insertion and some people can't tolerate them for long (or short) listening sessions. $1000 for earphones doesn't work for me. ~$300 is my price point a super-compact/portable item I use mostly for travel.
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.
