Just curious, I have a beat pro, love the sound, i know its original as bought from authorized dealer in the States, other than the good workmanship for the metal connector to prove its original, any difference in audio quality compare to fake 1. Reason being, trying to sell mine but many potential buyers asked for receipt etc which already missing, box threw away as too bulky to bring back to Msia, so only left the bag, manual, cloth, cable and the headphone itself. Thanks
