Wesley Review by One of the best value portable amps
My Nexus 5 has a terribly low volume output. I love listening to music during my commute, and I decided I needed to try an amp. I have used many desktop amps before, so I knew what to look for. The choices came down to a Fiio amp, the C&C BH, and the NX1.

With the NX1 almost half the price of the C&C, and with Topping being a well known provider of quality amps, I figured it would sound and work just as good. It does.

There is a slight emphasis across the lows, mids, and highs, but it is very slight. Sound remains clear and it drives my most power hungry IEMs with ease (Havi B3).

I also have owned this for over 3 weeks, playing it 3+ hours everyday, and still haven't needed to charge it. The 1000mAH battery lasts a long time.

It looks great, is compact, sounds good, and can power most power hungry earphones with ease. (Posted on 6/26/14)
Great I'm really happy with this product Review by Clement
Great amp for my headphones. Plenty of volume, and great sound quality on my Studio monitor Beats. I really like its mini look, pretty cool. I think it's the latest topping amp. cool.
