I have to say I was skeptical about the refurbished price being so low, but it was totally worth it. Headphones came fairly quickly and they're in great condition, completely new, no issues with rattling or anc, they didn't come in original box or anything but that's fine, they still came with the case and cables. I also went and compared them to an in store demo version and they are the exact same (but not nearly as greasy looking as the open box demo). Overall definitely worth the purchase, really loving them so far.
