FiiO E11K Kilimanjaro 2 portable headphone amplifier with Bass, Gain and Alps potentiometer for smartphones, music players and computers (electronic) 5
Have risen with the Fiio my headphones that I use normally home to operate sometimes with the phone. This he met fully. It is well made and has a really very good for me battery life. When the headphones are designed for mobile devices, it can still get a lot out of volume and can by the "bass boost" function itself out from among the Apple headphones still a lot. If now the in-line remote would work by today's mobile headphones, the small 6 star would get. I am fully satisfied and highly recommend him for any of his time either Hi-Fi headphones from time to time to operate a mobile phone wants or wants to get more out sound and volume from its normal headphones.
