The DZ4 have an exhilarating chrome faceplate design with a beige-colored shell and sound.
When you search flexible IEMs with a balanced, neutral-warm profile, the DZ4 would possibly not disappoint. On the other hand, the ones yearning distinctive, colourful sound or thunderous bass would possibly glance in different places. With innovation and forged efficiency, the DZ4 cling their floor in the fee vary. I individually want LETSHUOER’s EJ07M and the detailed S12 over the DZ4. Even supposing they’re well-executed, the DZ4 may just use tuning and motive force upgrades to polish.
- Distinctive and cutting edge vented faceplate design
- Very good are compatible and end
- Great equipment – pointers, cable, and case
- Impartial tuning with wide attraction and occasional fatigue
- Tolerates and advantages from EQ changes
- The mismatched beige frame colour is abnormal
- Shorter nozzles than common
- Total sound profile is secure, now not outstanding or distinctive
- Bass authority and have an effect on are unimpressive and extremely ear-tip-dependent
- Technical efficiency is easily beneath the highest festival in the fee vary
The design alternatives of the LETSHUOER DZ4 are daring and intriguing, together with the internals. You probably have the right kind are compatible, the ensuing sound is… competent.
Good enough. Moderate. Positive.
Beige.
In point of fact, I’m now not bashing beige. Beige is secure, bland, and dull. For my style, it’s simply now not a riveting or colourful colour. Nor is it an exhilarating description of a valid profile.
Total, I’m a little confounded through the DZ4. The sound isn’t what I anticipated, and the are compatible is exasperating. Candidly, I anticipated extra and am disillusioned. Take note that is most effective my enjoy, and you’ll love them. Let me percentage with you why, plus the highs and lows.
Unboxing and First Impact
Design and Construct
LETSHUOER mated steel and resin for the DZ4. The original faceplate is CNC-milled anodized aluminum with an carried out sandblasting remedy, leading to a delicate matte texture that doesn’t simply select up fingerprints.
The DZ4 glance slightly delicate up shut.
The faceplate sports activities a formed letter Z with a perforated purple display at the back of the aluminum. The result’s an IEM with a semi-open again hollow space design, as a substitute of vent holes within the frame, intended to unlock power with out sound leakage or compromising isolation.
The resin frame is a 3-d-printed chassis produced in a joint effort with HeyGears, a number one provider. What’s maximum abnormal is the colour selection. I imagine that black or purple would had been a a long way higher design selection for the resin to check the faceplate.
The fast nozzles are a major problem for me, compromising the ear tip seal and ensuing sound.
The two-pin connectors are flush with the frame.
Cable
The silver-plated braided monocrystalline copper cable is a attractiveness that fits the faceplates, now not the shell. In spite of taking a look considerable, it’s mild and versatile, as are the pre-shaped ear hooks. Terminations really feel well-reinforced and sturdy. The cable doesn’t tangle, and the chin slider remains anyplace I put it.
There are 0 microphonics, which is track to my ears and yours.
Convenience
The DZ4 are light-weight and ergonomic. The shape itself reasons me no discomfort.
Not one of the incorporated pointers labored for me.
To catch up on the fast nozzle period, I searched my assortment for the tallest ear pointers I may just in finding, making an attempt to get a right kind seal. I discovered the yellow pictured pointers are compatible the most productive – even supposing I’m undecided of the emblem or style.
The cable ear hooks cling true to their form and are versatile.
Probably the most major problem, particularly for me, is that the moderately narrow shell and the shorter-than-average nozzle period lead to shallow insertion, deficient angling, and problem attaining a right kind seal.
Beneath the Hood
The DZ4 have 3 6mm titanium diaphragm dynamic drivers and a unmarried 6mm passive radiator attached to the dual-pin receptacle by means of a versatile revealed circuit (FPC) crossover board, lowering the load of the earphones.
Each and every of the 3 dynamic drivers has a particular function within the frequency vary. The addition of the 6mm passive radiator is meant to succeed in a quick and exact passive reaction to increase the low-frequency replica.
How Do the LETSHUOER DZ4 Sound?
For analysis, I pay attention to an excellent number of track via a lot of assets, together with DAPs (FiiO M15S), telephones (LG V20, LG V60), moveable DAC/amps (HELM Audio Bolt, DB12 AAAMP, TempoTec Sonata E44, Khadas Tea, Qudelix-5K) and desktop DAC/amps (S.M.S.L SP200, HIFIMAN EF400).
With an excessively low impedance of 12 ohms and a prime sensitivity of 104dB, the DZ4 are simple to force from any supply.
As famous prior to now, the frame and nozzle are too quick and slightly large, leading to a shallow insertion. I fight to stay the IEMs well-seated and sealed.
Those problems made comparing the sound difficult.
The soundstage is spacious because of the semi-open design, whilst the left/proper separation is obvious. Timbre is in most cases applicable, with occasional atypical shows within the higher midrange and decrease treble and a few tools sounding boring.
Again to beige.
The DZ4’s sound signature is reasonably balanced, ever so reasonably heat, and moderately bland, i.e., non-descript. The sound presentation is moderately muted and lacks pop. They’re high quality in the event you’re searching for a reasonably heat, inoffensive sound that won’t reason fatigue.
The upside is that the DZ4 are amenable to EQ changes, most probably because of the 3 dynamic drivers with separate frequency tasks. EQ could make the sound extra interesting and tasty for me, beginning with a 3dB bass shelf at and beneath 125Hz.
For this evaluate, I visited the next artists and their house places:
A captivating assortment from a number of continents, those numerous musical productions vary in ethnic origins, musical types, and explorations in audio.
Bass
I anticipated the DZ4’s bass have an effect on to face out with their energy aggregate motive force configuration. Alas, no. To cite Marvin the Martian: “The place’s the kaboom? There used to be meant to be an Earth-shattering kaboom!”
In spite of what the frequency reaction graph suggests, the bass is common, at very best, in each amount and high quality.
Bass supply, like several else right here, is a little ho-hum. Positive. I heard no distortion when listening at reasonable to loud volumes (for trying out). Assault and rot speeds are common for dynamic drivers. Answer is ok for herbal tools and track that’s not overly busy or technical.
Midrange
The midrange is provide, regardless that it might be extra detailed. On a favorable be aware, the DZ4 are easy and don’t come throughout as shouty because of the loss of noticeable spikes within the midrange frequencies.
Treble
The treble is a little shy, by no means shining with element and readability. This vary is moderately constrained with some notable veiling. The treble lacks air and liveliness. The upside is that in case you are treble-sensitive, the DZ4 is not going to reason you ache. There’s a contact of sibilance on uncommon events within the decrease treble, regardless that not anything I’m distracted through.
The place to Purchase
Who Must Purchase This?
When you’re searching for all-purpose, competent IEMs without a obtrusive faults and neutral-warm tuning, the DZ4 shall be a very good selection. The DZ4 don’t seem to be for you if you need a definite, coloured, distinctive sound signature. When you love thump and prime element, you’ll even be very best off taking into account other merchandise.
I beg you to discover different reviewer and proprietor views, as I could also be an exception. In spite of my opinion, the DZ4 would possibly fit you nicely. Given the DZ4’s innovation, design, and general efficiency, they’re aggressive in the fee vary and could also be sufficient to win you over.
Ultimate Ideas
I’m smitten with LETSHUOER’s distinctive EJ07M, love the thrill and detailed S12, and am regularly stunned through the Singer… much less so with the D13. Having auditioned the soon-to-be-released S15 planar magnetic IEMs, I’m assured they are going to be an impressive addition to the lineup.
It’s imaginable my expectancies had been too prime for the DZ4, particularly with the three+1 motive force configuration. I used to be hoping for standout bass efficiency on this value class and a few transparent difference from the contest.
The inventory tuning is neutral-warm and unremarkable. This isn’t essentially a adverse, simply my remark. The DZ4 have now not won my consideration or want, and candidly, they are going to now not be IEMs I will be able to spend extra time paying attention to.
Upgraded drivers, tuning adjustments, and a distinct coloured frame are had to make the DZ4 extremely aggressive IEMs.
Regardless, I’m nonetheless a LETSHUOER fan. To their credit score, the DZ4 are any other well-executed design possibility with additional diversification of their tuning, now not sharing a lot in commonplace with different IEMs within the present lineup. “Other strokes for various people” could also be the tactic.
Corporate Review
I’ve enjoy with more than a few LETSHUOER IEMs throughout their value and complexity vary, together with the phenomenal EJ07M. As well as, I’ve the entry-level tiny bullet-style Singer and the severely acclaimed planar magnetic S12.
LETSHUOER, prior to now referred to as Shuoer Acoustics, used to be based in Dongguan, Guangdong, in August 2016 through self-proclaimed IEM “geekers” and audiophiles with a median of 16 years of enjoy.
