What customers say about "Key Specs"
TOPPING NX3 HiFi Portable Headphone Amplifier (Black)
  • The mids and highs are superb. Amazing sound and infinitely better than other headphone amps in this price range.
  • With this DAC the bass is powerful and clear.
  • When I got mine today and open it up. Plug it on. Sounds great. What a little powerful amp.
  • Awesome amp, makes all sounds more clear, more robust, and definetly louder.
  • My NX3 was only a few months old when it lost one stereo channel. I contacted customer service to help and nothing.
Fiio A3 Portable Headphone Amplifier (Black)
  • It's just that good. The extended Bass really makes the bass much more pronounced without compromising the mid's and clean high's.
  • Highly recommend if you like loud music and good sound. Next upgrade is a better phone with a better dac!
  • Excellent portable amp. If you phone DAC produces no noticeable issues, go with this amp.
  • No DAC included in this unit, but for what it does and the price, it's a great little amp.
  • Please don't confuse this little DAC amp with a more expensive preamp/EQ. It's not going to dramatically change your headphone's frequency response.

  • This thing is small, a little bitty body of metal and this perfect.
  • Compact size makes it easy to carry. I recommend this.
  • I'm not pleased with the sound and the portable size.

What customers say about "Features"
TOPPING NX3 HiFi Portable Headphone Amplifier (Black)
  • Works great with my LG V20 and Monoprice M560 headphones.
  • Quality Features and Value make this an awesome HiFi Headphone Amp!
  • This quality portable amp improved the performance of every single headphone from Fully Open, Semi-open or Closed Backed headsets.
  • Other amps needed a little extra power and features, so I bought the Topping Amp.
  • I had an electronics tech try to fix all features, no avail.
Fiio A3 Portable Headphone Amplifier (Black)
  • Take it from me, this thing is the real deal! Overall I find that the sound quality is A+++! I like this features!
  • This a unique device because it has a pre-Amp this helps with the Kilimanjaro 2 producing a sharp clean sounds.
  • Even if you don't have a professional set of headphones this makes any of them sound premium. With a 10 hour battery, it's perfect for travel.
  • Phone rings sound like they are in my home. Dog barks sound like one of my dogs. This is cheap, simple to use, and does a fantastic job.
  • All of the vocals in any music dropped off. I tried turning on and off disconnecting cables and reconnecting still sounds like garbage.
