The NX7 is a powerful portable amp, and it's increasingly rare to find a portable amp that is as powerful and capable as this. A lot of people ask me, do we need an amp if the headphones are easy to drive, and I say, you may need it, but it's like adding a supercharger to your chain - the sound opens up. You have to have one to know the difference.
PAIRS WELL WITH THESE ACCESSORIES
EQUIPPED WITH A NEWLY DEVELOPED NFCA AMPLIFIER CIRCUIT FOR CLEAN SOUND
The Topping NX7 is the latest flagship portable headphone amplifier. Topping has developed an NFCA module specifically for portable amplifiers like the NX7. The NFCA (Nested Feedback Composite Amplifier) module achieves clean and high power with low output impedance. The low idle power consumption allows for extended battery life. The NX7 delivers a value of 0.00007% for THD + N and 135 dB for SNR, making it one of the cleanest portable amplifiers.
AMPLE POWER TO DRIVE HEADPHONES AND IEMS WITH 3-STEP GAIN SETTINGS
Topping NX7 has been engineered with careful consideration to drive full-sized headphones and even sensitive IEMs with ease. This is possible with the 3-step gain settings embedded in the NX7. With the help of its 3-step gain setting, NX7 can easily power full-sized headphones. The NX7 can output 180mW of high power under a load of 300Ω. Using the low gain of the NX7, you can drive IEMs. At -13.8dB, the low gain option gives you plenty of room to control the volume of extremely sensitive IEMs without damaging them or your hearing.
EXPERTLY BUILT WITH AN ANTI-MISTOUCH DESIGN TO PREVENT DAMAGE ON THE NX7
The team of designers at Topping have gone to all lengths to ensure that users of NX7 have the most enjoyable and worry-free operation when using the device. This ideology is reflected in the final design and offers a thoughtful solution to common issues. The Topping NX7 is designed with corner guards at both ends to protect the entire panel, effectively preventing the volume knob from being accidentally touched in the pocket and reducing the possibility of breaking the headphone plug. This design is considered and resolves issues with portable devices so you can enjoy music without worry.
OFFERS 20 HOURS OF BATTERY LIFE, LOW OUTPUT IMPEDANCE AND DUAL OUTPUTS
Even though the Topping NX7 is a slim and portable device, it packs a punch in battery life. The NX7 is optimised to offer a long battery life. It can be battery-powered for 20 hours at a medium gain and can reach 10 hours at high gain. Along with this, the output impedance is 0.1Ω. As a result, even high-sensitivity IEMs do not cause timbre colouring. With Topping NX7, you can use it without hiss noise without having to think about sound matching. The NX7 also offers dual headphone outputs with 3.5mm and 4.4mm connections to plug your headphones or IEMs.
BUNDLED WITH A VARIETY OF ACCESSORIES TO HELP YOU GET STARTED WITH NX7
Topping NX7 comes bundled with an array of accessories to help you get started with the NX7. You get a USB charging cable and a 3.5mm to 3.5mm audio cable for quick connectivity and charging the NX7. You also get a rubber pad and rubber band to place your NX7 and avoid damaging the device. Along with these, you get a user manual and a warranty card to get you started. The inclusion of these accessories is thoughtful and allows you to get started with NX7 right out of the box.

Customer Reviews
Was looking for my first stack build which was portable enough to carry and can power my demanding cans, couldn't find nothing special or exact combo i was looking for.
Otta nowhere topping announced their NX7 and that same time lotoo announced lineout feature coming for both Paw S1,S2, and right away i made up my mind for Paw S1 + NX7 combo.
Thanks to hpz for bringing in the NX7 lightning fast to india, and here we are, powerful yet low profile stack for my 650.
NX7 is clean, transparent + powerful amp, adds no coloration to source (thanks to NFCA technology), well built, in hand feel is awesome, battery backup is great also even on high gain, don't own iems so couldn't check channel imbalance in low volume. Can drive my 650 in high gain at 1-2 o'clock on volume pot with more than adequate volume and room left for much more. It's a awesome device and just what i was looking for.
Now waiting for topping to release a fully balanced portable amp.
Form factor, design and sound quality are just great. Bought this confidently after reading other 2 reviews on HPZ and Joshua Valour’s review on YouTube.
As a side note, Raghav should actively start reviewing on YouTube as well!
I will just explain my set up here, I am using Apple MacBook Air M1 and Apple Music as source device and streaming service respectively along with Shanling M3X as dual DAC Line-out set-up and also as a source device as per convenience as well.
I need to use Sundara on High gain and Fiio FH5S Pro on Low gain to drive them to their full glory.
Also, this is a pure Amp device so you will need a DAC to improve the sound quality. Thanks.
We appreciate your honest review & amazing ratings, Girish M!
Didn't expect it to sound so good.
1400 mw at 32 ohm in such a small package, with a 4000 mAh battery, at this price. Unreal!
Pitch black background. Doesn't colour the output. Just does what it's supposed to do, amplify the analog signal. Tried it with my trusted duo of Sundara and Senn 650.
Loved the pairing with Fiio FD3. Terrific bass (this IEM is good, really good for it's price).
This setup of Lotoo Paw S1 (lineout) to NX7 gives my iFi balanced desktop stack a run for its money.
Might sound ridiculous, but, on some tracks this portable setup sounds better than my ZenDAC+Zencan desktop stack.
Hey there, nothing makes us happier than knowing you loved your purchase, hope you had a comfortable shopping experience & thank you for the great review & ratings!
The NFCA module embedded in the NX7 delivers incredible, clean and crystal clear sound and takes the performance of my Sundara to the ultimate level!
Ever since I got my Sundara, I have been searching for a portable amp which delivers justice to the extraordinary abilities of the Sundara. I first got myself a Hip Dac2. Through the balanced port it gave a decent output, but I had to crank up the volume to 90% to get a decent sound, leaving very little headroom. The X Bass offered some support on the bass front, but somehow, the sound was not with the X Bass on was not optimal to my listening sense.
Given the need for an amplifier, I paired the Hip Dac2 with my old Fiio A3 Amp. It was a definite improvement but still not what I was looking for. Distortion at higher volumes was discernible.
Given the specs and the reviews of the Topping NX7, it was an obvious choice. It pairs well with the Hip Dac and sounds incredibly detailed with an impressive soundstage, imaging and resolution. The problems with the X Bass in the stand alone Hip Dac configuration is no longer an issue and the bass blooms now. The NFCA circuitry is truly legendary and it makes all the difference. The Sundara never sounded better.
The way that I have configured the pairing is to keep the volume of the Hip Dac to Max and use the volume of the NX7 to suit my listening pleasure. X Bass is invariably set to on, save for some really bass heavy tracks. I use the gain to High in the Hip Dac and to Max in the NX7. This is the ultimate configuration for the Sundara given my listening needs.
The NX7 is a solid piece of electronics. It weighs over three times the Hip Dac (which is a DAC plus Amp). It looks and feels solid, just as an amp should be.
HI Ajit Kumar ,
We are so happy you took out time & elaborately reviewed the product. We are sure this will help our customers to make an even better & informed decision.
Headphone zone is a very Smart platform ,which cheats you with your hard-earned money.
Dont go to their false claims of 7 day return .
They will lie on your face .
I owned almost every decent portable headphone AMP out there and NX7 is the best of them period. It's powerful enough to drive almost any headphone out there. It's neutral, clean, dynamic and unlike the Topping AMPs I had not clinical or dry sounding.
I read a lot of reviews listing cons that it doesn't have DAC built in and I don't agree with them. It's more designed to use with your favorite DAPs and I am all for it.
And for the price it beats AMPs like iFi xCan, XD-05 Plus/Balanced comfortably.
Unlike the above AMPs NX7 absolutely good with IEMs too. What else you want out of $180 portable AMP. If you are looking for one, worth the blind purchase.
Hey there, nothing makes us happier than knowing you loved your purchase, hope you had a comfortable shopping experience and thank you for the great review and ratings!
Very good portable headphone amplifier built like a tank. Good sound quality.
Thank you for your genuine feedback on this product, we're glad that you have such positive thoughts about the product.
