Just received and tried it out for 4-6 hours. Quality of the package is good and the device itselves seems solid but the sound is crapy with lots of cracklings and background noises (like capacitor charging), whatever headphones and wires I try. I'm very disappointed and do not recommand this device.

headphone output is having issues before using a even a full charge, the headphone output jiggles, with the audio cutting out tried 3 different headphones with the same results.

I tried it yesterday again and sometimes it would also make a rhythmic skipping track sound.

Just received and unboxed the NX3s from Massdrop. That was fast: Thanks Massdrop!!! Looks like Topping has a winner here for a lightweight portable amp that will drive the HifiMan HE4XX’s well. So far I’ve driven the NX3s with my FiiO X7 Mkii, and the EarStudio ES100 BT DAC/Amp. Obviously both are in amp only mode. Those two combinations drive the HE4XX’s well playing Tidal and HiByMusic player. I generally listen to my music fairly loud and like some accentuated bass. The NX3s seems to have a slightly warm signature and I didn’t need bass boost to really enjoy it. Bass boost works fine and the HE4XX handles it well. I’m running the NX3s at between 70-100% volume (depending on source) to get the music to my personal listening levels. To me the ES100 supplied by BT from my iPhone 8 produced the cleanest sound and I was able to tweak the sound signature slightly to my likeing with the built-in EarStudio EQ, (adjustable by app). Listening to Tidal I had to push the ES100’s gain up (overdrive) by about 6db to get levels up to where I like them. !00db+ at headphones. When driven by the FiiO X7 Mkii there was plenty of power but I noticed a little distortion at High volumes. Lowering the X7’s output slightly, cleared that up and still produced good clear listening levels. Right now it looks like my go-to setup will be the iPhone > ES100 > NX3s just because of it’s convenience and portability. Maybe some time with my Hiby R3 too once I try it. For now my X7 Mkii will stay dedicated to my home tube amp, where it pairs nicely. If if anyone is wondering about how the Topping NX3s compares with the Xduoo XD-05 amp, the XD-05 does win hands down. Much more headroom on gain 3, slightly fuller sound and cleaner. But the XD-05 is a lot of luggage to carry around on my belt or stacked. So the NX3s will be suiting me very well as my new go-to portable amp for the HE4XX’s along with my Little Bear B4 tube amp (tubiness is just so addictive) rolled with the Burson V5i op amp and Urbanfun’s Transound One berylium driver headphones. I am continuously amazed how exemplary sounding the Transound One headphones are when it comes to detail, bass and fast driver response. (previously U.S. Mfg. RB Sound as the HP-2) Also, it’s combo with the modded Little Bear B4 is absolutely sublime. Cheers Edit: been listening to Lindsey Stirling with the NX3s, ES100 & HE4XX headphones; OMG they sound so incredible!!! The subbass on the HE4XX’s is amazing. Actually have goosebumps.

Make sure at Analog you go for a single, as they bulk package them in like 50. I'd try a sample there , if you just want to buy I'd try Mouser or Digikey as they sell singles..

I have received my unit. With HD650, loud enough on low gain (pegged). On max gain, I was using at about 1:00 position. Nice power boost (and headroom increase) when used with my SMSL Idea dac/amp, which outputs at a good line level (approx 2VRMS). So by extension, at Gain=1, at same loudness IDEA, now with headroom. With weak laptop output (not using external DAC), am left wanting for more power. I have no experience with amps with ample power, this is my first. Bass incredibly more defined, rest of spectrum seems clean. I think unit has good noise spec. Funny how now that bass is where it should be, I am noticing the veil on the other end more. I need to adjust to this. Also, so far listening on with youtube videos, so don't count me as an expert. Will try with flac files later, don't have on my chromebook. This unit sure is cute.

Amend to say, with weak laptop output, now have enough volume, but....not much headroom left over. Also, to clarify, the veil I was referring to is that of Sennheiser. Anyway veil is a stupid moniker. Headphone is soft at high end - noticeable more so with poor recordings (Youtube) which are themselves attenuated at high end. With good recordings, sounds just right.

Has anyone else noticed how similar this is physically to my xduoo xp2, which I rather like although it has been pointed out that all recharables trend toward doorstops/paperweights ultimately

Battery in this thing is user replaceable, I've swapped out op amps and noticed the battery is plug in style (Molex)

I have the NX1s and is pretty decent for the size. Solid construction not a sigle plastic piece in the case.

I'll attest as well. Nx1s is a very good value proposition. Bests the headphone output of a Fiio X3ii, which is saying quite a bit.

In answer to Burson owner, or rather additional question - will it even fit? The whole amp is 1/2 inch high including case.

People should not look at reviews or specs of older nx3 - different animal.
