Sealed, New In Box - Fiio A3 portable headphone amp - LOUD!

Description

I have a brand new, still sealed
Fiio A3
portable headphone amplifier.
It
packs a punch for such a small size (it's about 3.5" inches long by a hint over 2" wide).
Here are the specs:
Power supply:               Mini USB port
Maximum output power: 450mW(16Ω); 270mW(32Ω)；
Frequency response :     20Hz~20KHz
Signal-to-noise ratio：  ≥108dB THD: <0.004%
Charging time：            ~240min.

Dimensions：                91.2mm x 56mm x 13mm

This powerful little amp has been discontinued, so it's harder to find currently.
Happy bidding, and please let me know if you have any questions!
