## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent amp for a good price
*by A***R on August 2, 2017*

This is an excellent portable amp for your phone! It definitely gave headphones a cleaner sound and also really helped power headphones with high impedances. I have the Fostex T50rp Mk3 which need quite a bit of power to work and this did a pretty good job at it.Another thing I like about this is that it is built very well, everything feels solid and I don't worry about this breaking anytime soon. It's very sleek and small and doesn't make your phone too bulky. The volume control and ports are placed nicely as well.The battery life is rediculously good. I couldn't believe how long this thing lasts! Also I thought the price for this was very good for what you get.I would have liked to have seen better cables however. The mini aux cable that comes with it is very cheap and doesn't work very well.

### ⭐⭐⭐ Good But Not Great
*by L***A on June 19, 2015*

Sound and DAC were perfect, but it can be interfered by a phone (Makes noise when there's a phone near it.)

### ⭐⭐⭐⭐ Solid. Tiny. Accurate. Never-ending battery.
*by E***S on October 1, 2016*

Overall this thing is pretty much unbeatable at this price and this size. I've been using a C&C BK for the past 4 or so years and to be honest I still prefer its sound, but it does not function as a DAC and, truth be told, I'm probably just used to its sound. The NX2 is less coloring to the music, a more "clinical" sort of sound, which is far better than too much color if I had to choose.Some of the best listening I've ever had is plugged into my Lenovo using the NX2 as DAC and jumping that to the C&C and out to a pair of Triple.fi-10 IEMs. Pretty effing spectacular, really. I get the noise free accuracy of the NX2's DAC and the extra warmth and punch from the BK. Obviously that's slight overkill. :) Or is it?Anyhow - I don't go around with two headphone amps. I would say the NX2's amp fuction is a bit warmer and more "sparkly" possibly due to the high roll-off in the DAC stage another reviewer mentioned. Not that big of a deal - it sounds great. Beats the pants of the noisy and *extremely* inference-prone DAC onboard on my laptop. In comparison the NX2 is utterly SILENT during song pauses, to the point it was disconcerting because I'd gotten so used to hearing a bit of "running noise" as it were with this dang laptop.The amp stage sounds great, a bit better I'd say, but I've not listened nearly as much that way and honestly I'd still pick up my BK 50% of the time ... but the battery does last longer with the NX2 and it's thinner.... Though it is slightly wider and longer than the BK, the fact that its roughly the size of a credit card but is thinner than the girth of a pencil, it's just as, if not a bit *more* pocket friendly.Great little amp/DAC. I was gonna spring a bit more for the new FiiO Q1.... I'm glad I didn't.
