So the BeatsX have a lightning port, but the others have a micro-USB. Makes no sense. Stick to one...
I've never tried Beats as a brand for headphones. Always been on Bose (the wired earphone types) and been in love since the beginning. Now I am in need (literally) of something wireless. I really like the BeatsX (they are priced okay too, just short battery life at 6 hours which is a bummer since most flights are at minimum 6 hours for me and I travel a lot), but don't know if I should stick to my tried and tested brand, Bose, and just get the Bose SoundSport instead (same price and battery life, but of course no lightning port). Also, I like the look of the ear piece of the Bose when compared to the BeatsX. It looks like my MiE2s and they are super comfy.
