After speaking a bit with Jim NiceHCK i said i was a reviewer and he sent me a sample of the EZ Audio D4 with a huge discount.
I’m really happy to review this product as this was greatly reviewed on the web and i would like to remind everone that you can buy this product from the NiceHCK shop at the link below:
This link is by no way connected with me, it’s just the link of the product in the NiceHCK store on Aliexpress.
I would like to remember that my impressions, as i’ve already said in other situations, are subjective and that listening experience can vary depending on our ears, our ear canal’s shapes, the tips we use, the source we use and so on.
Tests were made by:
– Samsung Galaxy S7 Edge, with Neutron Music Player and Neutralizer
– AGPTEK m20 (Benjie S5)
– Presonus Audiobox iONE connected to my pc (without any kind of enhancement)
Drivers: 1 single 10mm titanium DD
Frequency response: 20-20000Hz
Cable Lenght: 1.2m
3.5mm Jack connection with L-type Plug
Cable has in-line mic
Colors avaiable: Purple and Silver
Product comes in a simple carton package in which we find a carry case for the headphones.
As soon as we open the carry case, we can see the headphones, 3 pairs of tips, one “keychain hook”.
Cable is braided and feels very nice while touching it. Tangling will not be a nightmare as this cable is not prone to tangle.
A chin slider is present. Microphone is ok. The cable ends with a gold plated L-Plug 3.5mm jack.
BUILD QUALITY AND INTERNALS
The headphones are made of metal and feature a minimalistic design that shouldn’t trick you about the quality.
There are 2 vents: 1 near the nozzle (to prevent the driver flex) and 1 in the backside of the shell (which should give “air” to the DD).
Internally a good 10mm titanium dynamic driver is the one that has been chosen to make these little beasts rock.
The nozzle features the usual metal grill which prevents earwax to go into the nozzle.
COMFORT AND ISOLATION
The simple and minimal design makes the fitting easy: there are no problems wearing these with the cable that goes down straight even because they are pretty lightweight.
Tips are subjective so comfort is even based on the tips you’re gonna choose. Isolation is average.
I mostly listen to EDM and subgenres with preferences on Dubstep, Future Bass, Dark downtempo, Midtempo, Bass house, DnB, Hardstyle, Psy and so on.
I even listen to many vocal oriented tracks moreover if singed by female voices.
Low end is really important to me: i always search for V-shaped sound with clear mids and good soundstage.
Lows: surprising. Sub-bass has good extension and can produce a good rumble. Not at ZS7’s level but this microdriver is really impressive.
Kicks are fast with good decay, i didn’t expect good thing about this but i have to ask being forgiven. I think these sound way better than my old Memt x5 in this region.
Bass is not boomy and they sound full with good body, without being intrusive in the mid region.
KZ EDR1 has a better sub-bass extension while i find the bass to be better on these D4.
This isn’t certainly a strong basshead IEM but can really be enjoyable by everyone with a deep, precise and well extended low end.
Mids: V signature is obvious here. Vocals sound a bit distant but keep their natural timbre.
Sometimes they sound a little bit on the cold side, maybe because of the lower mids sounding with less warmth than i expected. Products in this price range are usually very warm. That can be a good thing though, considering i feel they’re more analitic than the EDR1 and ED9.
Highs: treble emphasis is concentrated on the upper treble with a high roll-off. Highs are not fatiguing but they keep a good level of detail. Lower treble is smoother than i expected without any kind of earcutting peak, no sibilance is detected apart from some tracks that are very prone to sibilance.
Soundstage is above average with good depth and width. Height is average. Imaging is really good and instrument separation is great if we consider the price of these, even listening tracks which feature multiple instrument layers.
These are the things that make this earphones astonishing for their price.
I didn’t try them with an amp so i can’t say if they improve or not.
NiceHCK is offering a very interesting product in the ultra budget segment that is well built, lightweight and aesthetically difficult to hate.
The EZ Audio D4 really have to be considered if you want a great product without breaking the bank, and you really get something that is worth 3x times the price you pay for these.
We’re speaking about a pair of IEMs that cover really well the entire frequency spectrum without any problem that can easily give fun at a very low price.
If i didn’t know the price of these and someone has told me to try them, i’m sure i would have said these were at least easily 30$ worth.
Thank you NiceHCK for the test sample!
