KZ ZS10 Pro 2 (Linsoul x KZ) Hybrid IEMs Review
A hybrid IEM that the page describes as a KZ and Linsoul collaboration, with a 10mm dynamic driver and dual 31736 balanced armature drivers, listed from $54.99 with or without a microphone. It suits buyers who want a 4-level switch and a three-way electronic crossover circuit.

Our verdict
A hybrid IEM for buyers who want a stated 10mm dynamic driver with balanced armatures, a 4-level switch and a microphone choice from $54.99. Look elsewhere if you need one clear driver count, since the page words it two ways, or want impedance and sensitivity figures, which the listing text does not provide. The main caveat is that the performance and sound claims are the maker's and were not checked.

The page presents the ZS10 Pro 2 as a collaboration between KZ and Linsoul, sold under the store title Linsoul x KZ ZS10 PRO 2. Its text lists a 10mm dynamic driver with dual 31736 balanced armature drivers, although a heading says 1DD+4BA. It adds a 4-level switch and a three-way electronic crossover circuit, and it starts at $54.99 across two orderable options.
Options and pricing
Two orderable options are listed under Mic: STD at $54.99 and With mic at $55.99, so the microphone is the only price step. The page names no color or plug choice, shows no crossed-out price and gives no cable length. The cable is described only as a detachable silver-plated IEM cable.
How it compares
The KZ AS16 Pro starts at $55 and its spec line mentions 22955 BA and 8 BA, while this model starts at $54.99 with a 1DD+4BA heading. The KZ AM16 starts at $56 and mentions 16 BA, and the KZ PRX starts at $53.99 with its Drivers row reading Enhanced Sensitivity.
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.
Before you buy
Linsoul says it was founded in 2016 by the Crazy HiFi team to bring Chinese HiFi makers closer to listeners worldwide, and that it now sells other makers' products alongside four brands of its own, THIEAUDIO, Kiwi Ears, ZiiGaat and Tripowin (checked 2026-11-11).

Questions before you buy
How many drivers does it list?
The page heading says 1DD+4BA, while the text describes a 10mm dynamic driver and dual 31736 balanced armature drivers. The page does not reconcile the two.
What does the 4-level switch do?
The page calls it a 4-level custom tuning switch built in as professional filters for different sound preferences. It does not say what each level changes.
What options does it come in?
Two: STD at $54.99 and With mic at $55.99.
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, soundstage and detail claims, and its comparison with HiFi standards, are the maker's claims and were not checked here.
- The page says KZ collaborated with Linsoul on the model; the listing text gives no further detail on what that involved.
- The page gives 1DD+4BA in a heading and dual 31736 balanced armature drivers in the text; neither impedance nor sensitivity appears in the listing text.
- 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.
