The Topping NX1 has been designed for MP3/MP4/mobile phone/computer that can not get best effect of high impedance from the headset due to the low power to improve the power and sound quality.

0.000015% Distortion

* Splendid combination of Amplifier
* The topping NX-1 use high performance chips
* amplification and can bead to reach the extreme distortion degree index of 0.000015% almost zero distortion.

Classical designed circuit

* Op-amp circuit still adopted the mature classic op-amp +buffer design.
* The best balance between high quality and reliable lasting durability.
* high frequency low resistance capacitance, very low loss and resistance
* NX-1 voice is as brilliant as Steinway piano which is with 50 years history.

Innovation Power Supply Design

* USB intelligent charging.
* 1000mAh large-capacity lithium polymer battery makes the battery life can reach max 4 hours.
* Full play to the op-amp and guarantee the good performance.
* Drive high impedance headphones with enough dynamic level range.
* Can adapt to the charge output of computer USB port and variety of Plugs.
* Automatically adjust the suitable charging current.
* Only need 1 hour if charging via 2A supply.

Humanized Function Indicators

* With Power LED & Charge LED indicator.
