R.I.P MTW4s after two months

I bought the MTW4s right at the release. Unfortunately after two months of daily use, at least 4 hours, I got a high piched noise on the right bud with random cut outs. Sound is even getting low after a few minutes until it died. Cleaning and factory reset to no avail. Amazon came to my rescue, as always, I am out here with my money. As much as I like the sound, which is still the best I ever heard, no second chance, no repair or replacement for me. Sorry, not after the MTW3s debacle. I just hope Sennheiser will be aquired by a big and trustworthy company who got the means to clean up their quality department. I wish you guys got more luck than I had with your Sennheiser products.
