I am shopping for a Hi-Fi headphone (upgrade my Superlux HD661) and come across this review. I am about to decide on Xiaomi Mi Hi-Fi Headphone cost around RM320.00. Any advise from Audio guru between Elysium Libretto & Xiaomi headphone. I am more consent with the sound quality and comfort for long hours usage. Music I play is more to pop, acoustic and sentimental songs.
