I had a similar experience to what others have posted. They broke after I had had mine for about 9 months. 9 months of extremely light use. These were not a daily driver just curious about them. I ordered mine from Amazon and contacted the company. They sent replacement parts, and were very responsive in terms of customer service. When I explained that there's no way to replace the pieces unless I desolder and fully disassemble that side of the headphone they sent a full replacement pair. So far the replacements have been okay, but again, I don't use these daily.
They sound okay. I don't use them anymore because I'm afraid they'll break. I give M&O a plus for customer support but I can't recommend the headphones.
