Check out BuzzFeed's full write-up on these headphones.
I actually bought a pair of these a couple weeks ago and I am completely in love! I don't get excited about electronics and didn't think I would see what all the fuss was about, but I totally do. First of all, I love all the colors they come in (I got metallic purple) and the sound quality. And they are SO COMFY!!!! Yes, you do have to get used to figuring out which side goes in which ear because they are a little oddly shaped, but that's what makes them feel great — they've got a flat part that lies on the flat part of your ear (very technical terms I know) so they feel like a perfect fit. Plus, they come with three different sets of ear pads in different sizes so you can make them just right for you.
Promising review: "Compared to MANY other earbuds that I've had that cost $75, $100, $150...these sound as good as any of them. I'm astounded! I use these for running. I figured for $8, I could afford to sweat up a few of these and replace them whenever I needed to. I'VE RUN 1,500 MILES WITH THESE in the last year and a half! I've gone through four pairs of New Balance shoes, two iPod Shuffles, three pairs of sunglasses, and I'm on the SAME set of earbuds! And THEY STILL SOUND GREAT! They stay in my ears, too!" —Gene Goodell
