Agree Massdrop should definetly clarify on that matter. At the moment all reviews are irrelevant since they already announced re-tuning. Looking at the massdrop page seems like people stopped buying it. It's no longer going well. My guess they will repeatedly make new drops of 58x at 149$ until 5000 units sold in the coming month or two. Another important aspect is that CES 2018 is coming in a few weeks. Many people are eager to find out what Sennheiser has to offer before deciding on getting 58x or 6xx.
