Meet the Topping Audio NX1s. This tiny, portable headphone amplifier packs in a powerful punch with an output power of 150mW x2 (32Ω) which can drive just about any headphone. It uses an OP+BUF circuit and has a THD+N of 0.0005% (300Ω). Unlike standard amplifiers which can support only CD-quality i.e. a frequency range of 20Hz-20kHz, the NX1s supports a range up to 100kHz! Hence, it's certified Hi-Res by the Japan Audio Society.
At normal volumes, you can use the normal gain to reduce noise. If the input is weak, simply turn up the gain. The NX1s also lets you choose between a clear, neutral sound and mega bass for deep, punchy low frequencies. The 1000mAh battery gives you 40 hours of playtime. Low battery? Charge it for a mere 4 hours to go from 0% to 100%.
Great attention to detail has been paid while designing the NX1s. The aluminium body has been crafted using high-precision machining while the markings (& alphabets) are engraved with laser. The operating knob has been designed with two "claws" to ensure that it's not mistakenly turned when you put it in your pocket. They also protect the headphone plug from being fractured.

It was just perfect for my Beyerdynamics dt770 pro (80ohm). There are two switches on the Amp, one for the extra bass and one for extra gain. If you have a V shape flat sounding headphone and Whenever you need some extra bass to vibe just turn on the bass switch and if you need extra volume turn on the gain switch. If you turn both gain and bass on at full volume the sound becomes a little distorted but only half the volume is enough for headphones under (300ohms).
Don't worry about sound quality loss rather it makes sound come out even clearer as it's a Hi-res player !
I use it on my phone sometimes too...works preety good with my one plus 7 pro !
The bettery life is amazing too...it actually shoked me at first for how long it lasted...charged it for like 3-4 hours and it worked for more than 39-40 hrs of continuous use!!
If u buy a expensive headphone and its volume is not enough or you feel like something is missing or... u're not blown away by it, just buy this plug it in and boom !! You'll be surprised how good this make headphones or IEM's sound. Buy the Nx3s if your headphone is more than (300ohms) i was going to buy that but im broke as hell after buying the dt 770 pro xD and thank you headphone zone for the quick delivery got the Amp in like 3 days, will continue shopping from your site !!
This is going to be a lengthy review. Read if you have time.
Yes, I like to call it the mini amp. At its price point and for 99% of the music listening folks this is all you need to introduce yourselves to a pocket sized headphone amplifier.
It delivers a clean and distortion free amplification to the source.
Ordered on 21st and received 22nd Nov 2020. The received product too was well packaged and in mint condition.
The NX1s Experience:
Setup: DAP-Fiio X1 II; DAC-S.M.S.L. SK 10th; Samsung mobile phone; Laptop-running Foobar in 7.1 / DSD/ Stereo with DTS Sound Unbound/ WASAPI/ ASIO and IEM-Tin HiFi T2
I have now been testing the new amp for almost a week, couple of hours daily since. Interesting fact: Plugged in right out of the box, have not yet charged it still and the charge indicator on the unit is still blue.
Used with Mobile: I use the combo of my phone enabled with Dolby Atmos or Tube Amp Pro feeding to NX1s. I will list a few of my favorite tracks used for testing later below.
As stated above with those audio effect settings, the overall dynamics are way better than phone's direct output.
Used with Fiio DAP: I have been using the Fiio X1 II for the last 3 years. This DAP offers two method of sound output. One I can use the headphone output (from system settings) option and enjoy the processing of the internal DAC. In this setting the NX1s does a very clean amplification with the gain and bass set at normal. In this mode neither a gain or bass boost on the NX1s makes much of a difference, only the overall amplification is desirable here.
However, in the second mode of using the Fiio with lineout option from the systems settings (it outputs a solid 1.7 Vrms (10 KΩ/1 kHz)) and this when amplified through the NX1s is splendid. At no gain and bass boost the music is as enjoyable as when you turn on gain and bass. I never go beyond 10 O'clock point on the volume knob, unless it is a very quite recording.
Used with S.M.S.L. SK 10th DAC: This entirely changed my experience of how beautiful the music sounds through Tin T2 matched with NX1s amp. I was already enjoying the SK 10th DAC, been using this for almost 2 years now, through USB input this DAC supports multichannel audio. I upmix certain tracks on Foobar to 7.1 channel and enable DTS Headphone: X, the experience is beautifully spaced, immersive audio with all the frequencies well amplified and tighter bass. This works well with gain on or off and certain tracks do get a lift from bass boost on.
Personally, I feel the lower frequencies are a bit rolled off (quite sharply) on the NX1s and the bass boost gives a big leap between 70 to 100 odd Hz. Nothing substantial in the sub bass region. Overall, for a near neutral sound, NX1s is a great beginner or for most the only amp sufficient (as long as you don't fall for the audio world's snake oil), the further refinements and upgrades in terms of hearing perception are not worth the big money. However, they do justify the crazy to spend on high-end HiFi. For the most part if you stream from Spotify, Gaana, Saavan, etc., or don't understand the place for the source in playing back audio, don't think twice blindly and safely buy yourself the Topping NX1s.
