Quick Disclaimer: I'm beginner and just casually listen to music without thinking much about it. I may use terminologies that are more personal but will do my best to describe it. These are also my own opinions, I did not read any reviews prior to making my own(basically going in blind) so if you have your own comments or perhaps any feedback regarding my review or the IEMs, please don’t hesitate to share your thoughts.
The gear I’m using is just really simple: ASUS TUF Laptop, Roseselsa 9039 Amplifier and DAC(review coming soon!) and the LETSHUOER DZ4.
Big thanks to LETSHUOER for sending the DZ4 to our local community for the review tour. Looking forward to working together with you!
I’d also like to extend my thanks to Sir Mars, Sir John and Jhetner for giving me the opportunity to be part of the review tour and extend a helping hand in writing reviews and testing the gears, without them I would not be making this review. I cannot thank you guys enough.
So let us begin.
The LETSHUOER DZ4 is definitely a game changer; if you’re a newbie/beginner like me and just casually listen to music without the technicalities you’d probably think that a 69$ IEM wouldn’t make any difference and you’re better off spending less than 20$ but oh boy I was wrong. This is one of those rare occasions that money does indeed go together with quality.
The Unboxing Experience
The outer box sleeve has Z which goes well with the fact that this IEM is called the “DZ4”; it's even textured on the orange parts so plus points for that.
The Hi-Res Audio certification is also present so you know that you’re in for a treat; unlike the IEMs that I’ve bought(Salnotes Zero, Wan’er, Chu 2 and Castor Bass), they don’t have the Hi-Res certification but still sound great otherwise.
Flipping the outer box sleeve over you can see specs of the IEM. From the frequencies, impedance and build material.
No frequency response graph was included though which isn’t a big deal but is needed for a better reference in case you need to compare it to different IEMs and their sound signature.
Unboxing feels like a brand new iPhone, the IEMs and the carrying case are the first to see and inside the case is where the cable and ear tips are stored. I do appreciate that they included a strip of velcro to not only to keep the cable from unwinding but also keep the IEMs stored neatly should you put them aside for a while.
I'd also like to mention that the IEMs have a metal faceplate and the chassis/shell is 3D Printed Resin which gives it a nice matte finish.
At first I thought the carrying case was made out of metal but it's made out of plastic though it doesn’t feel cheap and inside the case has a thin layer of rubber.
The only thing I dislike about the case is that it smudges easily and cleaning it doesn't seem to restore it back to it's flawless state.
Specifications
Sensitivity: 104dB/mw(@1kHz) | Impedance: 12ohms +_ 1%(@1kHz) |
Frequency Response: 20Hz-40kHz | Distortion: _< 3%(@1kHz) |
Cable is 1.2m 0.05m*216 silver-plated monocrystalline copper.
And the IEMs are equipped with three(3) 6mm titanium dome dynamic drivers and a 6mm passive radiator.
Listening Experience
The DZ4 is like hearing music within music
(if that makes sense), the statement
“you get to hear a different dimension” applies in this case. Have you ever had the experience when using higher quality headphones you'll hear some parts of the song you've never heard before? Yeah it's that feeling. While it doesn’t make you hear celestial beings or the 5th wall, it opens a new gate when listening to music and gives it more dimension.
Wearing the IEMs for a long period of time doesn't cause any fatigue, the weight and fit of the chassis adds to the listening experience that you don't have to constantly adjust because over time it gets loose.
The flexible cable doesn't tangle even if you roll it up loosely or tightly, it unwinds very well; did I mention that it doesn't make noise as you move around? Gone are those days that you hear the cables brushing over your shirt or the surface and just focus on the music.
Instruments really pop off in these IEMs, it’s as if you’re in the studio when the band is playing. You get to hear the strums and strikes which adds to the immersive experience. You’re not only just listening to the music, you’re actually there when the music was recorded; which is something I would describe this feeling.
The Treble and Mid-range frequencies are on point, even if the volume goes up there is no audible distortion and doesn’t hurt your hearing
(though please listen at safe levels).
Sound staging, imaging and depth are also worth mentioning here since there is a decent amount but could be improved; you’d have to go back and forth looking for the right song and listen closely which I find a bit of a hassle but when you do then you'll know the difference. I guess that’s the “different dimension” I was talking about.
As a bass head I can say that there is a minimal amount of bass but lacks in sub-bass, you won’t get that
"feel" that would shake your eardrums but is enjoyable to listen to. While some songs do have a punchy bass, the IEMs don't make up for it.
My standards have definitely gone higher after using these since I only have experience with budget IEMs within the 15 to 25$ range, spending a little more will yield different results and this is one where it is super worth spending more.
Again I would like to thank LETSHUOER for sending these over to our local community for a review tour and giving everyone a chance to listen to this 69$ IEM and compare it with the other IEMs in line for review or the existing ones we've bought.
Cheers and happy listening!
