NiceHCK EB2: Simply Good

Hello everyone!
After some speaking with Jim from NiceHCK he sold me a pair of EB2 for some cents in order to get a honest review.
I will write some stuff about the NiceHCK EB2 which were quite interesting from the Aliexpress page.

You can find the EB2 at the link below for the Aliexpress Store:
Or here for the Amazon Store:

I just wanna precise that my impressions are subjective and that listening experience can change depending on source, pads and so on.

Test were made on:
– Galaxy S7 Edge Smartphone
– Presonus AudioBOX iONE connected to my PC with no Enhancements actived

Technical specs:
Drivers: Single 14.8mm PEK Dynamic Driver
Sensitivity: 116dB
Impedance: 32ohm
Frequency Response: 15 Hz – 25000 Hz
THD < 0.1% @1kHz
Cable lenght: 1.2m±5cm (Non detachable)
Plug Type: Straight


Common carton package from NiceHCK.
We find the appreciated carry case with the NiceHCK logo, the earbuds, a little clothespin and a variety of pads (5 pairs mixed donut pads and full pads).


Cable feels great with a nice touch and feel. It seems very durable and high quality and features an appreciated chin slider. No mic.
The downside is that it isn’t detachable and that could be useful in order to replace the cable if in someway people accidentally break it.
It ends with a 3.5mm gold plated jack but you can find a 2.5mm balanced plug too.
I personally could try it as i did not have a balanced output.


The shell is made of metal and it’s really well assembled. It features 2 big vents in order to advantage dynamic driver’s work and on little vent at the end of the shell.
Red stripe earbud is the right one, while the blue stripe earbud is the left one.


Personally, i usually find earbuds uncomfortable for long session. The EB2 are fairly comfortable as soon as you can wear earbuds without problems.
Fit can be tricky if you’re not up to these kind of headphones especially if they’re around this size (i personally feel sick wearing mx500 shells after half an hour for example, but i have very little ears).
In any case, the EB2 do not provide an excellent isolation due to their earbud design but with the right pads and medium volume you will be ok.


Let’s get into it.
Now the critical factor that decides if something has to be tried or not: how do they sound?
I mainly listen to EDM subgenres, Dupstep, Future Bass, Euphoric Hardstyle, Bass House, Midtempo and downtempo, darkwave, drum’n bass, but i even listen to many vocal tracks, moreover female ones.
I always search for IEMs that have a little bit of emphasis in the lower region, and can sacrifice mids with some recession if they still sound clear and natural. I love vivid and sparkling highs if they’re not at a headache level.
V-shape signature is my favourite one.

Test were done with double pads: full pad on first, then donut pad at last. This should make the low-end a little bit more punchy and the treble a little bit more forward after the full pad wearing.

Lows: Lows on the EB2 are really good. Sub-bass has nice extension and kickdrums have a nice impact. Basses well textured and sound with the right body. The 14.8mm driver and the back vents really help keeping the low region immersive for people who like heavy genres.

Mids: really smooth. Male voices sound good thanks to the little mid-bass hump and female voices are intimate due to the upper mids lift. Synths and instruments get a little recessed place without being very recessed. Voices are forward instead.

Highs: really vivid with good detail retrieval. Treble is not super emphasized and it’s fatiguing at all. Treble roll-off is not going to ruin your treble as it’s not low and there’s enough air.

Soundstage is not particularly big, with a bit above average width and average height and depth.

The EB2 are anyway not easy to drive and i do not advice people using them with a simple smartphone. While connected to my Presonus AudioBOX iONE, they really “open” showing more potential, and I’m sure if you connect them to a very good amp they can really show you how well they sound.


NiceHCK provides an EBX little sister which should sound good at less than half the price.
I personally do not own the EBX so i cannot speak about it, but i have to say these earbuds can really nail it.
With the right pads you can put out of these just what you want and you still have in any case a great earbud that can sound good with everything, but i advice using them with a dedicated amp (i think an economic Fiio A1 should do the job well for these kind of earphones) or at least sources with enough power to drive them.
I am sure NiceHCK is doing very well with their product and i hope they keep their actual quality which is really top notch: the EB2 is another proof of their good work in the chi-fi world.
