KZ Merga In-Ear Monitors Review
A KZ in-ear monitor that the page describes with two stacked dynamic drivers, a 10mm and an 8mm one, and an electronic crossover. For the 8mm driver the page gives 330 impedance, with no unit, and 104 dB sensitivity. It starts at $12.99 with a Copper cable.

Our verdict
An in-ear monitor for someone who wants two stacked dynamic drivers with an electronic crossover and a choice of Copper or Silver cable from $12.99. Look elsewhere if you need a clear impedance unit or sensitivity level, since the page gives neither. The main caveat is that the page's sound, accuracy and tuning statements are the maker's claims and were not checked here.
- Best for
- Someone who wants a dual-dynamic-driver IEM with a choice between a Copper and a Silver cable.
- Skip if
- You need an impedance unit, a sensitivity level or a named connector, none of which the listing text gives.
The KZ Merga stacks two dynamic drivers, a 10mm super-linear inner magnetic one above an 8mm one, and the page says an electronic crossover on the PCB divides the frequency range between them. For the 8mm driver the page gives 330 impedance, with no unit, and 104 dB sensitivity. The listing starts at $12.99 and has two options, a Copper cable and a Silver cable.
Options and pricing
There are two options by cable: Copper at $12.99 and Silver at $13.99. The page describes two cable versions, a silver-plated one and an OFC flat cable one, while the options are named Copper and Silver. The variants list the microphone choice as STD only, although the page's spec rows also name With Mic, and the listing text names no connector or plug type for either cable.
How it compares
The KZ EDX Pro starts at $13, the CCA Polaris at $13 and the 7HZ AERO costs $12.74, set beside the Merga's $12.99 to $13.99. No spec line is shown for any of them, so the Merga's two stacked drivers cannot be compared with theirs from this data.
Shipping
- Methods and costs. The store's shipping page offers Standard Shipping (4PX, Yanwen or Yun Express), free for most countries, and Express Shipping (DHL Express, FedEx or SF Express) at 15-50 USD depending on the country, free for orders over 270 USD in most countries (checked 2026-11-11).
- Delivery times. It says an in-stock order ships within 3 working days, Standard takes about 2 weeks after shipping out (up to 1-3 months for some countries, and the store makes no refund for that transit time) and Express takes about 3-7 days. Festive seasons and other circumstances can change the timing.
- Taxes and fees. The buyer pays any customs, import or processing fees. The page says Standard via YunExpress is tax-inclusive for some countries, that remote areas can carry extra Express charges, and that a parcel refused or left uncollected over taxes is deducted two-way freight and may be destroyed with no refund.
- Where it ships. The page says the store can generally ship to most countries by Express and many by Standard, and to confirm Standard with the team for your country. It cannot ship to PO boxes or APO/FPO addresses and can only use Express to Hawaii. It does not name the US, Canada, the UK, Australia or New Zealand, so confirm before you pay.
- Lost parcels. If a parcel has been in transit for at least 3 months, the page offers a one-time reshipment or a full refund for orders under $50 and a 50% refund for orders above $50.
Returns and warranty
- Returns. The return page allows returning any non-customized product that is still factory sealed within 30 days of receiving it, with the buyer paying the shipping. Email [email protected] within that period; the store asks for the return to be shipped within 5 working days of the RMA instructions and in most cases processes a refund within 5 business days of inspecting it (checked 2026-11-11).
- Opened items. A product opened within the first 7 days after delivery can be returned for the price minus a restocking fee of 35% of its retail value, including when it still works properly.
- Refund or credit. The buyer can choose a refund to the original payment method (PayPal or card) or store credit; with no answer within 48 hours of confirmation the default is store credit, which can also be prioritized during promotions, final-sale events and for items 40% or more off retail.
- Not returnable. Customized products, including faceplate designs, are non-refundable, and the page says the same applies to carry cases, cables, ear tips and other accessories, "due to hygiene purposes". If one item in a package is defective, incorrect or missing, the refund or replacement covers only that item.
- Warranty. The page gives a 1-year warranty on products, excluding carry cases, ear tips and other accessories, and 3 months on cables and adapters, from the date of purchase. It covers factory defects that affect proper function, not damage from human error, negligence, accidents, dismantling, water, abuse or modification (checked 2026-11-11).
- Not covered or limited. It does not apply to items bought elsewhere (AliExpress, Amazon, local dealers and the like), prize or giveaway items, normal wear or colour change, commercial use, or items that were stolen or went missing. Coverage is limited for products 40% or more off retail, for review units and for items repaired or modified by anyone Linsoul has not authorized.
- Claims. Email [email protected] with the order number, the issue and photos and videos of the fault. The store may ask for the unit back for a replacement. It covers shipping for some defects reported within 7 days of delivery if the fault can be shown on video or photo; after 7 days the buyer ships it back. For wrong or missing items an unboxing video of the whole sealed parcel is required.

What we liked
- The page lists two dynamic drivers, a 10mm and an 8mm one, with an electronic crossover on the PCB
- The page gives 330 impedance and 104 dB sensitivity for the 8mm driver
- Two cable versions are offered, Copper at $12.99 and Silver at $13.99
- A replaceable cable and a single-button in-line remote are listed
Worth noting
- The impedance of 330 has no unit and the 104 dB sensitivity has no level, and both are for the 8mm driver only
- The page gives the 20Hz to 200Hz deviation as 8dB or higher, which reads oddly and is not explained
- The listing text gives no connector type, plug type or cable length

What we couldn’t verify
- Per the page, 330 impedance has no unit and 104 dB sensitivity has no stated level, and both belong to the 8mm driver; the listing text gives no connector, plug or cable length.
- The page says the deviation from 20Hz to 200Hz is controlled to 8dB or higher and within 2dB between 200Hz and 1kHz; that wording is unclear and was not checked here.
- The page's sound descriptions (accuracy, bass, mids and highs, brighter, neutral and smooth cable versions) are the maker's claims and were not checked here.
- We have not read an independent review of this product or the store, and the store's own ratings were not verified. We read the store's catalog description only: a specification table or image shown just on the live page was not read.
- The shipping page names no US, Canada, UK, Australia or New Zealand times or fees: its figures are general and we could not confirm them for these countries.
