I'm interested in possibly purchasing some HE-300s. However, I'm concerned about the part in this picture breaking: Head-fi member CanDude posted a picture here on head-fi of his HE-6s breaking at that spot / part. If I were to buy HE-300s and that part (I think it's called a gimbal) were to break out of warranty, would I be able to pay to have a replacement part shipped out to me? I don't really want to buy the headphones if I can't obtain that replacement part out of warranty. Thanks.
