Triple 6mm Titanium Dome Dynamic Drivers

The DZ4 represents LetShuoer's latest hybrid driver earphone, featuring a unique driver setup. It combines three 6mm diameter titanium dome dynamic drivers with one 6mm diameter passive radiator driver. These drivers are connected to a dual-pin receptacle through a Flexible Printed Circuit (FPC) crossover board. The DZ4 incorporates a four-way acoustic tube design, which is an integral part of the two-way crossover circuit. All of these components are housed within a resin shell with a CNC-milled faceplate on top. The DZ4 includes a 4-core silver-plated monocrystalline copper cable with 2-Pin connectors and a 3.5mm SE headphone jack.

CNC-Milled Anodized Aluminum Casing and Semi-Open Design

The LetShuoer DZ4 is an elegant In-Ear Monitor with a universal shape that was designed in collaboration with HeyGears. The monitor shell combines high-quality 3D printed resin material in a pleasing pastel white color for the main body and CNC-machined aluminum material for the faceplate.

Innovative Driver Configuration

The DZ4 features a distinctive driver setup, combining three 6mm diameter Titanium Dome Dynamic Drivers with a single 6mm diameter Passive Radiator Driver. These drivers are intricately connected to a dual-pin receptacle via a flexible printed circuit (FPC) crossover board. This design also incorporates a Four-way Acoustic Tube arrangement, an essential component of the Two-way Crossover Circuit.

Modern and Futuristic Aesthetics

The CNC-machined Anodized Aluminum faceplate showcases a futuristic aesthetic with interconnected dots and lines. This section boasts an orange finish that appears to have a neon-like glow. A mesh backing complements the semi-open back design of the LetShuoer DZ4. The inner surface of each monitor is equipped with a low-profile sound nozzle featuring small damping filters on top. Each earpiece includes a 0.78mm diameter 2-Pin female connector interface for secure connections. The rear surface of each monitor is adorned with LetShuoer branding and L (Left) or R (Right) indicators.

High-Quality 4-Core Silver-Plated Cable

The DZ4 comes with a 4-core cable featuring 216 individual strands, each with a diameter of 0.05mm. It is constructed from Silver-Plated Monocrystalline Copper and measures approximately 120cm in length. The cable boasts a braided design and is insulated with soft and flexible PVC in Gold and Silver colors.

Well-Designed Connectors and Accessories

The 2-Pin connectors are encased in metal housings, with transparent markings for easy identification (left for transparent and right for red). Near the connectors, heat shrink ear guides provide additional comfort during use. The cable also includes a metal Y-splitter and a transparent plastic chin slider for user convenience. It terminates with a 3.5mm single-ended headphone plug featuring a straight-profiled metal housing with LetShuoer branding on top. The plug incorporates a semi-transparent plastic strain relief for added durability.

Ergonomic Design and Noise Isolation

The LetShuoer DZ4 stands out as a comfortable In-Ear Monitor, primarily attributed to its ergonomic design and the use of lightweight materials such as resin and aluminum. These factors contribute to a secure and comfortable fit within the ears, particularly for individuals with average-sized ear concha. The passive noise isolation of these monitors falls within the average range, primarily due to their semi-open back design. However, they provide adequate isolation for use in moderately noisy environments, such as buses or trains.

Effortless to Drive

The LetShuoer DZ4 is an easily powered earphone due to its low impedance of just 12Ω and a sensitivity of approximately 104dB/mW at 1 kHz. This high compatibility extends to smartphones, tablets with a 3.5mm output, and USB dongles with relatively weaker amplification capabilities.

Shipping FAQ

Which countries do you ship to?

We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.

We cannot ship to addresses that are "PO boxes or APO/FPO".

*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.

How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*. 

*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.

Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.

Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes. No refund will be processed for such cases.

Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.

For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments. 
Please contact us before placing an order, should you have any queries regarding shipping.  

How long does it take to receive the order after it is placed?

For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products. 

Customized items will take a longer time. Please contact our staff for more information.

On normal non-sale days, once your parcel has been shipped out:

  • For Standard Shipping, it takes about 2-4 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country, its customs and other factors.* The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to Express Shipping or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.

*Note: Timings might be affected due to festive seasons or other unforeseen circumstances

What happens if the parcel has been shipped but not delivered?
  1. First, kindly contact your local courier using the local tracking number.
    If your parcel were to be in transit for at least 3 months, it may have been lost in transit.
    For orders below $50USD, you may either opt for a one-time reshipment of parcel OR a full refund of the amount paid in cash via PayPal/Credit/Debit card.
    For orders above $50USD, we will only process a 50% refund of your order paid in cash via PayPal/Credit/Debit card. Should there be any concern about Standard Shipping, you are encouraged to opt for DHL Express Shipping instead.
  2. Customers are to bear the consequences and fees incurred, if the parcel was undelivered due to any of the following situation:
    • Wrong address or phone number provided by recipient
    • Recipient was uncontactable when courier company contacted
    • Refusal to sign for the package by recipient
    • Lost or damaged parcel because recipient opted for “no-signature delivery”
    • Refusal to pay for the local tax/processing fee by recipient
    • Refusal to provide supporting documents for custom clearance by recipient
Who will pay for the import tax/custom fees

Customers have to bear any form of custom/import/processing fees that are applicable for your parcel.

Should you be unwilling to pay for the fees and reject the delivery of the parcel, you will still have to pay for the shipping cost. Linsoul will only refund the amount of your order after deducting the two-way shipping fees incurred.
