The thing is, I write almost never a recession but orient myself very good after recession texts! For this device I can give only the top grade, the performance is amazing, I operate the device with my iPhone 5 and a Sony MDR-XB700, Maximum capacity of small Fiio would mean that my eardrums burst! Many setting options for all tastes and all styles of music! Price and performance unbeatable !!!! I can only advise you to beat !!!!!!!
