Letshuoer DZ4's Review - Oddly Satisfying Bass

 

General/Packaging/Build/Comfort

Letshuoer is a company that most in the community would be familiar with. Particularly with their hit release such as the S12 Planar IEM which is widely received even up till today. I have reviewed their S12 as well as D13 in which both I favored and have positive experience with. Today I have their latest release which is the DZ4, which features 3DD+1PR(passive radiator) configuration. Passive radiator is more commonly used on speakers to create a deeper sounding bass. Letshuoer is fitting their DZ4 with this tech and let’s find out how does it perform. As with most of Letshuoer’s packaging, the unboxing experience is always positive, greeted with premium packaging which consist of a black premium looking storage case, IEM cable (too bad they are not available in 4.4 termination as an option), otherwise the cable itself is very good and solid, two types of eartips, namely the vocal and balanced. The shell is 3D printed with a semi open metallic faceplate, which in a way contributes to the soundstage as well. The nozzle, however, is slightly big which might be an issue for some. Overall i’m comfortable wearing the DZ4 for a long period of time.

Foreword

My review is solely based on what I hear via my equipment and I never consider my reviews to be objective in any way rather a subjective approach. Do take into consideration that everyone’s ear anatomy is not the same, so the psychoacoustics perception might be different as well, but i believe it will not stray too far

Sound Impression

The first thing that I noticed when I put on the DZ4 is the soundstage, it sounds open and in fact, it is quite capable technically. The bass is also satisfying as well, I noticed the PR is mostly affecting the mid bass as the mid bass has more body and packs a little more punch to it. Timbre is very natural which is expected from a dynamic driver, no odd/metallic sounding instruments here. It also sounds quite neutral to my ears.

Bass

• Bass has good texture and control, has very good speed

• Speed is good and handled Metallica’s Lux Aeterna without sounding bloated

• Bass doesn’t bleed into the mids

• Sub bass does have some rumble when the track calls for it, it doesn’t go really deep but it is good enough for EDM enjoyment, tested this listening to Ping Pong by Armin

Mids

• Mids are not recessed nor overly forward, quite detailed to my ears

• Male’s vocal sounded a little lacking in terms of body, overall it's not too bad, i tested this with Zhao Peng’s song, it doesn’t sound that full, but its not bad either

• Female vocal such as Faye Wong does sound fuller compared to male’s, very enjoyable

• Lower to upper mid range are very lush and enjoyable, even at high volume, it doesn’t get harsh

Treble

• Treble is smooth and not fatiguing, energetic enough but not excessive to the point where its harsh

• Extension is good and it has good amount of air, i believe the design of the faceplate also contributed to this

• Detail retrieval is good, higher expectation is just nitpicking in my opinion

Soundstage/Imaging

• Good sense of width and height, depth as well, it doesn’t sound boxy and very open sounding to my ears

• Imaging is quite good, instruments can be pinpointed easily

Driveability

• DZ4 is not hard to drive, but it does scales with power as with most dynamic drivers

• Amping it does exhibit better bass control in terms of tightness and a little bit of refinement on the top end

• However it does scale with source, in terms of how the dac/amp affect it in terms of colorization of the sound

Final Thoughts

Letshuoer has once again hit the right spot balancing between good sonic performance and pricing it right. At 89$ a pair, this is an absolute steal in my opinion. You get a high quality IEM with solid build quality, good technical performance and it is versatile enough for various genres. Bass has sufficient quantity and good quality, treble that’s energetic yet not fatiguing. Highly recommended!
