NiceHCK EP10: Tricky Slammers

Hello everyone,
after some time spent with my EP10 I decided to write something about them.
These were found in the Fukubukuro that I’ve bought in November from the NiceHCK store.


You can buy the EP10 from the link below:…olare-HIFI-Bass-DJ-Subwoofer/32953684155.html

I just wanna remember that my impressions are subjective as listening experience may vary due to ear canal’s shape, ear ability, tips used, source and so on.

Tests were made through:
– Samsung galaxy S7 Edge with Neutron Music Player and Neutralizer
– AGPTEK m20 (Benjie S5)
– Presonus Audiobox iONE connected to the PC with all enhancements OFF

Drivers: 1 single DD driver (PET & PEN diaphgram)
Sensitivity: 95±3dB/mW
Impedance: 32ohm
Frequency response: 20-40000Hz
Cable lenght: 1.2m
Non-detachable cable with straight gold plated 3.5mm jack


Simple carton package. We find a NiceHCK hard carry case which contains the IEMs and two packets of eartips (3 normal pair of Spinfit-like tips and 2 pairs of double flange tips). Packaging is minimal but the carry case is really appreciated and the double flange tips are as well.

Cable is great and you can feel the good quality while touching it.
I have two versions of the EP10 and the silver version seems having a softer cable (black cable) compared to the copper-colored cable’s one, even if the cables are identical. There’s a very useful chin slider that allows us to adjust the length of the splitted cable after the V and this is really appreciated as most of the earphones in this price range doesn’t feature it.
Cable ends with a straight gold plated 3.5mm jack.
It is possible to choose the mic version too.
The pics taken show the non-mic version of the EP10.

Shell is completely made by reflecting metal and it’s really well built.
The shell features 4 little holes on its back which help the dynamic driver taking some air and one in the beginning of the nozzle in order to prevent driver flex.
The anti-wax grill is there and it’s made of metal as well.
L and R informations are printed on the shells for the left and right channel.
The EP10 feature a 10mm dynamic driver that should give glory to the low end at first impact.

All seems excellent till now but now it’s time to say what isn’t or better saying.. it’s time to make some warnings.
Comfort is really subjective: i didn’t find a good compromise on how to wear these and I do not advice these IEMs to people who don’t want to spend their time for some tip rolling.
EP10 are really tip sensitive so you really have to find a good combination with the tips if you wanna enjoy your listening experience 100%.
The IEMs have nothing wrong but the nozzle is really short and many tips are just not made for a so short nozzle. That being said, you could even find the stock tips to be ok and it will probably be just like that, but I wasn’t so lucky.
Isolation is good as soon as you get a good fitting with the right tips.



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 with good soundstage and airy sound is my favourite one.

Lows: Excellent. It’s the star of the show in the EP10. Response is deep with good impact. Sub bass is well extended and they’re always there when needed with a top notch rumble that can be difficult to find even in more expensive IEMs.
Kicks are well bodied and fast with good resolution.
Bass sounds full and not intrusive, with good definition.

Mids: Voice presentation is really natural with a warm timbre that gives a great feeling.
Mid-bass has a little lift that. Mids are laidback and some synhts are left behind but still keeps a good level of detail. Low end keeps the stage while the rest of instruments take a place in the backseat even in complex and much layered tracks.
The warm tone really helps male voices and the upper mid helps voices coming out a little bit more, as they’re not really intimate.

Highs: Treble rolls off too early, but there’s a fair amount of detail.
Highs have a soft warm tone and can be a real deal for treble sensitive people.
Everything sounding in this frequency range is smooth but I would have preferred a higher roll-off in order to get some more sparkle.
This is obviously a tuning decision so it’s intended in the sound signature choice.

Soundstage is really wide with average depth and height.
Three-dimensionality is ok but could be even better with a bit more depth.
Instrument separation is fairly good, imaging is precise.
I do not have an amplifier in order to test if it can improve the sound on these. If you have one you can try amping these and see if they benefit from amping.


NiceHCK offers a real “new” product with a unique tuning that is well built and features a great cable offering us an appreciated carry case as well.
EP10 can be an awesome choice for those who listen to bass heavy music, moreover if you listen to dark genres like Dark downtempo, midtempo, tribal trap and other heavy edm subgenres.
They aren’t certainly made to be all-rounders but its unique signature makes them really interesting even because it’s nearly impossible to find something tuned like the EP10 in this price range.
I wouldn’t advice these to people like me instead: I like fun sounding earphones but I really need sparkling highs which these do not feature (this speaking about the earphones without an amplifier).
