Christopher Tan has posted a review of the Xiao Mi headphones ($79) at Enjoy the Music. His conclusions:
“Whilst not the most resolving headphones, it is by far an absolute bargain and should held against all other high end headphones for comparison to justify the additional costs. Mi headphones make for great cans for the daily commute to work, jogging (really, yes), where you need some high tempo music to get through mundane work or exercise. They really do most genres well and are without peer. They are for people who wanted to like Grados but gave up due to physical and aural fatigue.”
