Here's what I looked into
Is there any other that will be a good pair with the andes
By portable, do you mean you will be using it outside on buses, on walks, etc?
The Philips Fidelio X1 is a wonderful headphone and i would HIGHLY recommend it, but the only problem is that its not a headphone meant to use outside the quiet comforts of your room.
Some headphone choices:
Sol Republic Master Tracks
Sony MDR 1R
Sennheiser Momentum Over Ears (if you can find them used. Not on ears... would not recommend on ears)
Some In ears:
Vsonic GR07 BE (seems to be rare to find past few weeks)
Aurisonics ROCKET (search them up on kickstarter, theyre VERY promising)
Sony XBA 3
