Our verdict

A single-option IEM for someone who wants a detachable 0.78mm two-pin cable and a listed distortion figure at $19.54. Look elsewhere if you need a choice of plugs or colors, or impedance and sensitivity figures, since the listing text gives none of those. The main caveat is that the page's tuning and sound descriptions, including its VDSF target mention, are the maker's claims.

Best for
Anyone who wants a dynamic driver IEM on standard 0.78mm two-pin connectors with no options to choose.
Skip if
You want a choice of plugs, colors or a microphone, or impedance and sensitivity figures.

Moondrop's Chu II is a dynamic driver IEM sold as a single option at $19.54. The page lists an aluminum-magnesium alloy composite diaphragm dome, an ultra-thin CCAW voice coil, alloy casted shells and a CNC machined brass nozzle with a replaceable filter at its mouth. The cable connects through standard 0.78mm two-pin connectors, and the page gives a non-linear distortion figure of below 0.05%.

Options and pricing

The page shows 1 orderable option at $19.54, so there is no color, plug or microphone choice to make. The page also shows $22.99 crossed out, which is the store's comparison price and was not checked here. The listing text mentions standard 0.78mm two-pin connectors and says the cable can be swapped, but the page does not describe the plug on the included cable.

How it compares

The KZ Pisces starts lower at $18.99, the CCA Polaris Pro at $19.90 and the SGOR Venus at $19.99, against a flat $19.54 here. The Chu II has no option menu, so the price is the same for every order, and its page names a distortion figure of below 0.05%.

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

What we liked

  • The page lists an aluminum-magnesium alloy composite diaphragm dome and a CCAW voice coil
  • A detachable cable on standard 0.78mm two-pin connectors, per the page
  • The page gives a non-linear distortion figure of below 0.05%
  • A single option at $19.54 means no choices to compare

Worth noting

  • The page gives a distortion figure but no impedance, sensitivity, frequency response or cable length
  • The page gives the below 0.05% figure without saying at what level it was measured
  • The page does not name the plug on the included cable
  • The first-of-its-kind diaphragm claim is the maker's, with nothing on the page to check it against

What we couldn’t verify

  • The page says the tuning follows the VDSF target response and calls the sound refined; these tuning and sound descriptions are the maker's claims and were not checked here.
  • The page says the diaphragm is a first among budget IEMs and gives a distortion figure of below 0.05%, with no measurement conditions; neither was checked here.
  • Per the page, the length and plug of the included cable and the earpiece weight are not stated.
  • 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.
