ND X12 Hybrid In-Ear Monitors Review
A hybrid IEM from ND with a 10mm dynamic driver and balanced armatures, listed from $49.90 in Black or White with an optional microphone. The page describes a replaceable four-strand wire on a 0.78 double pin slot, which suits buyers who plan to swap cables.
Our verdict
A hybrid IEM for buyers who want a replaceable wire on a 0.78 double pin slot and a choice of Black or White, from $49.90 with a microphone option. Look elsewhere if you need impedance, sensitivity or a frequency range before buying, because the listing text gives none. The main caveat is that the armature count is worded two ways and the sound descriptions are the maker's claims.

- Someone who wants a hybrid IEM with a replaceable wire on a 0.78 double pin slot and a microphone choice.
- Skip if
- You need a settled armature count, or any impedance, sensitivity or frequency figures.
ND's X12 is a hybrid IEM whose page describes a 10mm nano dynamic driver working with balanced armatures named 50024*4 and 30095, a setup it calls a bilateral 12 circle iron mix. It gives no impedance, sensitivity or frequency range. The shell is CNC aluminum alloy per the page, and the starting price is $49.90 across four orderable options.
Options and pricing
There are four orderable options made from two colors, Black and White, and two microphone choices. Black and White cost the same, while the With Mic version is $51.90 and the STD version is $49.90, so the microphone is the only price step. The page shows no crossed-out price and gives no weight for either shell color.
How it compares
Against the TRN TA2 at $49.80, whose listing mentions 1DD, 2BA and a hybrid layout, the X12 starts at $49.90 and its spec line mentions only a hybrid layout. The KZ ZSX is $49.99 and mentions 5BA and 1DD, and the CCA Rhapsody starts at $49.99 and mentions a hybrid layout as well.
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.

We have not read any independent review of this product or of the store. Ratings and owner reviews shown on the store's own pages are the store's and were not verified.
What we liked
- The page names the drivers: a 10mm dynamic driver plus 50024*4 and 30095 balanced armatures
- A 0.78 double pin slot and a replaceable four-strand silver-plated wire are described
- Black and White cost the same; only the microphone changes the price, $49.90 against $51.90
- The page describes three adjustment levels (it calls them tuning levels) and a CNC aluminum alloy shell
Worth noting
- The listing text gives no impedance, sensitivity or frequency range, so the match to a source is unknown
- The balanced armature count is worded two ways (50024 double parallel and 50024*4) with no plain total
- Every figure and claim comes from the page and none was measured here
- No weight or cable length is given
Questions before you buy
What drivers does the ND X12 use?
The page describes a 10mm nano dual magnet dynamic driver with balanced armatures named 50024 and 30095, which it calls a bilateral 12 circle iron mix. It words the 50024 group both as double parallel and as 50024*4, so the exact count is unclear.
How does the cable attach?
The page describes a gold-plated double pin and a 0.78 double pin slot, with a standard four-strand silver-plated wire that can be replaced. It gives no plug type or cable length.
What do the options change?
Color is Black or White at the same price. The microphone choice sets the price: STD is $49.90 and With Mic is $51.90.
Can I return it if I change my mind?
The return page allows returning a non-customized product that is still factory sealed within 30 days of receiving it, with the buyer paying shipping. An opened product returned within 7 days carries a 35% restocking fee. Refunds go to the original payment method or to store credit, which is the default if you do not choose.
How long does shipping take?
The shipping page says in-stock orders ship within 3 working days. Standard Shipping takes about 2 weeks after shipping out, up to 1-3 months for some countries, and Express takes about 3-7 days. Standard is free for most countries; Express costs 15-50 USD and is free over 270 USD (over $499.99 for large items such as headphones and desktop DAC/AMPs).
Does Linsoul ship to the US, Canada, the UK, Australia and New Zealand?
The page says Linsoul can generally ship to most countries by Express and many by Standard, and to ask the team about Standard for your country. It names no restriction for the US, Canada, the UK, Australia or New Zealand, but it does not list them either, and it can only use Express to Hawaii.
What warranty does it have?
The page gives a 1-year warranty on products from the purchase date for factory defects, not for human error, accidents or modification. Coverage is limited for items 40% or more off retail and for review units, and it does not apply to items bought from other sellers.

What we couldn’t verify
- The page's tuning and sound descriptions (three tuning levels, detail and sound field claims) are the maker's claims and were not checked here.
- The page words the balanced armature group as a double parallel 50024 and as 50024*4, and calls the whole a bilateral 12 circle iron mix; the listing text gives no plain per-side count.
- The listing text gives no impedance, sensitivity, frequency range, weight or cable length.
- 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.
