Powerful Portable Amp

An ideal pairing for your smartphone or portable digital audio player, the Topping NX3s headphone amplifier is designed to drive headphones and IEMs with low distortion and noise. It significantly improves upon the power output of its predecessor, the NX3, with an output of 545 mW at 32 ohms, giving it the ability to drive more demanding full-size cans. The front panel has two gain settings and a selectable bass boost, allowing you to easily toggle between these options. 

Note: At checkout, choose black or silver.
