Light, Thin & Portable

Weighing a scant 2.6 ounces and measuring less than a centimeter thick, the Topping NX2S DAC/amp can be strapped to the back of your smartphone for on-the-go listening or connected to your laptop at home. This sequel to the NX2 maintains the original’s great value and sleek, minimal aesthetic, and kicks it up a notch by increasing the output power and lowering the amount of noise. The DAC section supports files up to 192 kHz/32 bit. The built-in battery provides 40 hours of playback time and charges in less than 4 hours using the included USB cable. Compatible with iOS and Android phones and tablets, as well as PC computers (drivers required for Windows), the NX2S comes with all the cables you need to use these devices.

Note: At checkout, you’ll have your choice of color: black or silver.
