A:Answer New. Earbuds have a finite lifespan, and if you got a pair used from someone who really used them, the drivers could be worn. I do not know if these get checked when they're officially refurbished, but I would always recommend new ones. There's just a lot that can go wrong, especially in earbuds that have this much packed into a small package.
I had those Beats. I liked them a lot for working out and the battery was amazing, but wasn't blown away by the sound, microphones or features. They lack noise canceling, unlike the Buds and just can't compete with the sound, solely based on the fact the hardware used in the Buds are miles ahead now. I didn't mind the Beats and enjoyed using them, but after using the Buds, it's not competition in my eyes.
