I just bought AKG K450 from MunkongGadget Paradise Park today. Very near my house and now very trendy shopping mall. I unpacked it and used it for 2 hours and got pain in my left ear. I wonder if this is the case of bad ear cup manufacturing? I am letting my friend to use it next week and see if he will experience the same ear pain on the left like me.
Does the manufacturer guaranty on bad ear cup making?
I also saw eBay selling AKG K450 for only $50. Why it is so cheap in eBay?
