Query: Good Sound, but cheaply made

I purchased these headphones 6 months ago. For the first three months I was pretty happy with them. Great sound quality, they really reduced outside noise on noisy bus rides I take, and they were light and easy to carry.However, while taking them off my head, they broke. The plastic piece holding the earphone simply snapped. I wasn't too rough with them or anything.Reading the warranty more closely, I discovered it said "Invalid in the United States and Canada." This is a European company so apparently the product is not warranted in the US.I am going to try sending them back to a service center here in the states, but I would never buy these headphones again. They are too cheaply made. If you spend $50, your headphones shouldn't break.
