About: FiiO Kilimanjaro-2 A3 Headphone Amplifier (Black)

The all aluminum-alloy body and chassis of the FiiO E11K portable headphone amplifier shields against electromagnetic interference and the built-in rechargeable 1400 mAH battery provides approximately 16 hours of operation on a four-hour charge via mini USB port. For I/O, it features an 1/8" stereo auxiliary input and an 1/8" stereo headphone output.

For controls, the amplifier includes a low-high gain toggle switch, a rotary volume control, and a fully discrete bass boost circuit that can be bypassed to decrease interference and lower the overall noise floor.


  • All aluminum-alloy body and chassis increases metal texture and increases shielding from electromagnetic interference
  • New toggle switches are more reliable and easier to read and operate
  • Pre amplifier OPA1642: Serves as the voltage amplifier, with great layering and medium and high frequency extension
  • Power amplifier AD8397: Serves as the current amplifier, with great control of low frequencies and smooth drive ability
  • Bass On: Boosts bass effect without influencing the overall sound field
  • Bass Off: Bypasses bass circuit, decreases interference and noise floor so as to ensure the purity of the sound quality
  • Can work while charging: 1400mAH built-in battery ensures more than 16 hrs of battery life
