So I just got mine back today. I thankfully only had to wait a week, even if it was 2 days over the promised time period. I guess I'm just in an area of the country that isn't as congested with returns. But still, that's really saying something, given what others in this thread have experienced with wait times.
The email I was sent to pick them up said that they were giving me MY REPAIRED pair of BeatsX. But when the guy at the Apple Store gave me my Beats, WHATTYA KNOW! It's a replacement, just like everyone else in this thread.
When I asked what was wrong with them, he said, "Unfortunately we can't know anything after we send them off to the warehouse."
When I brought up this thread, he said, "Unfortunately we can't acknowledge it until Apple thinks it's a frequent enough issue." Well, given what many of you have said, I would think it's a "frequent enough issue" if some people are having to wait up to two months to get their Beats returned.
Apple/Beats' lack of transparency is the crappiest part about them as a company. Because, good god, why should anyone EVER conceive that an Apple or Beats product has a flaw. Imagine what the masses would think!
I am going to try what @ukbilleh said. If they brick again and Apple/Beats doesn't come out with a fix, I will never purchase a pair of Beats again and I will be switching to JayBird. You here me Apple? YOU WILL LOSE A CUSTOMER.
