Our verdict

A five-driver balanced armature IEM at $550 for someone who wants universal 0.78mm 2-pin sockets and a stated crossover and filter design. Look elsewhere if you need listed impedance, sensitivity or cable details, since the listing text gives none of them. The main caveat is that the sound, dynamics and ease-of-driving descriptions are the maker's claims and were not checked here.

Best for
Someone who wants a five-driver balanced armature IEM with 0.78mm 2-pin sockets for their own cable.
Skip if
You want impedance, sensitivity and cable details stated on the page.

Softears' RSV is a five-driver balanced armature IEM, and the page says Softears developed it as an easier-to-drive alternative to the RS10. The listing describes a crossover of six components across the five drivers, acoustic filters 3D printed to an accuracy of 0.1mm, and universal 0.78mm 2-pin sockets for cables. It is one option at $550, and the listing text gives no impedance, sensitivity, cable or plug details.

Options and pricing

The RSV has a single option at $550, and the page shows $729.99 crossed out beside it, the store's own comparison that we did not check. The listing mentions universal 0.78mm 2-pin sockets and says users can choose their own cables or switch to Bluetooth options, but the listing text gives no cable length, plug type or bundle contents, so there is nothing to configure.

How it compares

The Softears RSV-MKII is the same $550, and its name marks it as the second version of this model. The Yanyin Moonlight (2023 Version) is $551.65 and its entry mentions tribrid and electrostatic drivers, whereas the RSV lists balanced armature drivers only. The QoA Martini is $539.10 with no spec mention in its entry.

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).

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 gives the driver count (a 5-driver BA design) and the crossover component count
  • Universal 0.78mm 2-pin sockets are named, so users can choose their own cables per the page
  • The acoustic filter method (3D printing) and its accuracy (0.1mm) are stated
  • One price, $550, with nothing to configure

Worth noting

  • The page says it is easier to drive but the listing text gives no impedance or sensitivity figure to show it
  • No cable or plug type is named, only the 0.78mm 2-pin sockets
  • Tuning, dynamics and soundstage descriptions are the maker's words and cannot be checked from the listing

Questions before you buy

How many drivers does the RSV list?

The page describes a 5-driver BA design, meaning five balanced armature drivers, divided by a crossover of six components.

What connector does it use?

The page says the RSV has universal 0.78mm 2-pin sockets, so users can choose their own cables, and it also mentions switching to Bluetooth options without naming them.

Does the page give impedance or sensitivity?

The listing text gives neither. It says the RSV is far easier to drive than the RS10 and reaches satisfying dynamics from phones, which is the maker's claim and not a figure.

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

  • Per the page, the tuning, dynamics and timbre descriptions, including the HRTF-based tuning method, are the maker's claims and were not checked here.
  • The listing text gives no impedance, sensitivity, frequency response, cable or plug details; the page says only that it is easier to drive than the RS10.
  • The page calls the RS10 a benchmark and says the RSV took a year and a half of research; both statements are the maker's 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.
