Hi.I hope this Helps.
C&C BOX+ Portable Headphone Amplifier
:Summary of Specification:
Business card size suits all low and higher impedance headphones
Two levels’ Gain Control brings more freedom to adapt your audio sources and music.
Dedicated compensation design for*various headphones and individual hearing preference make Sound reproduction quality*approximate perfect. Two compensations include: low frequency compensation and*harmony*sound stage*expansion compensation. If*compensation switches are complete off, it will be*a common high-fidelity, low/high impedance headphone amplifier.
Using a low voltage level---AD822 IC for outstanding performance in its pre-amp section, and the output level using this super high quality*IC with 250mA output capacity expansion/headroom, and*expanded four times parallel connection expanding current flow, to provide very wide high dynamic range, high Damping Factor and high control power. Whether*under 32 ohms or up to 300 Ohms,*the output signal is basically unchanged. So perfect impedance match to low & high
Headphones is achieved.*
Volume potentiometer using authentic ALPS potentiometer, to ensure high quality of sound.*
Batteries are using specially customized outstanding industrial Dual-Lithium rechargeable batteries with full protection, conduct adequate capacity, coherence is excellent.**
Internal design contains intelligent voltage charging circuit, full automatic Trickle Up. It will not be over-charged, 9-12V supply voltage compatible external hard disks, to supply a wide range of power source. You can*listen to music while charging without interference or any communication made.*
Maximum output power: 200mW+200mW output.
Headset plugs impedance: 8-300 ohm Auto Match.
THD+N (total harmonics distortion plus noise) : below 0.005%
