Our verdict

A fit for someone who wants a planar IEM with a listed 14.8mm driver and a cable with detachable 2.5mm, 3.5mm and 4.4mm connectors at $179. Look elsewhere if you need impedance or sensitivity figures, since the listing text gives none. The main caveat is that the soundstage, layering and low-frequency descriptions are the maker's words and were not checked here.

Best for
Someone who wants a planar IEM with a 0.78mm dual-pin receptacle and detachable 2.5mm, 3.5mm or 4.4mm connectors.
Skip if
You need impedance, sensitivity or weight figures that the listing text does not give.

A 14.8mm dual chamber planar driver, a 6mm Passive Filtering Module (PFM) and a dual acoustic tubes structure with filter crossover make up the LETSHUOER S15, which the page also calls the Third Generation. The single orderable option costs $179. The cable is described as a 216-strand silver-plated monocrystalline copper design with a flush-mounted 0.78mm dual-pin receptacle and detachable 2.5mm, 3.5mm and 4.4mm 90-degree angle connectors.

Options and pricing

The page lists one orderable option at $179 and shows $329 crossed out beside it, which is the store's own comparison and not something we checked. The cable's 2.5mm, 3.5mm and 4.4mm connectors are described as detachable 90-degree angle connectors, so the plug choice is made by swapping connectors on the same cable rather than by picking a variant. The listing text gives no accessory list.

How it compares

The 7HZ Timeless starts from $186.99 and its listing text mentions planar, and the SIMGOT SuperMix 5 is $186.99 with planar and bone conduction mentioned. The RUMAUDIO Blues is $179.10 with no spec cue shown. The S15 costs $179 and its page lists a 14.8mm dual chamber planar driver.

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.
  • This listing. The page shows a crossed-out price of $329 against $179, which is 40% or more off, so the page's limited-coverage rule for heavily discounted items may apply.

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).

What we couldn’t verify

  • The page says the S15 has an expansive soundstage, rich sound layering and an enriched low-frequency experience; they are the maker's claims and were not checked here.
  • Per the page, the listing text gives no impedance, sensitivity, frequency response, weight or cable length, and the crossed-out $329 is the store's own comparison.
  • 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.
