How is that even possible!? These headphones are absolutely remarkable. I wear headphones 75% of my day have owned Samsung, Bose, and Pioneer and somehow a pair of $25 headphones crushes them in every way.
It's not just the quality either. They are incredibly comfortable as well.
When I first used them, I thought they were broken. Turns out they work independently from one another. As in, I can turn on/off the right and left headphones whenever I choose.
As for the battery life. That does leave a little to be desired, but given the perks, I don't mind at all.
