Our verdict

Suited to someone who wants a 4.4mm or 3.5mm plug choice with a standard 0.78mm 2-pin cable from $19.99, plus a stated earpiece weight of 6g. Look elsewhere if you need impedance or sensitivity figures, as none are in the listing text. The main caveat is that the page's sound descriptions are the maker's claims, so lean on the listed hardware.

CVJ sells the Kira with a 10mm dynamic driver that the page pairs with a PET composite diaphragm and a lightweight CCAW voice coil. The shell is described as a resin body with a metal frame and an inlaid glass faceplate, and the page gives 6g per earpiece. A standard 0.78mm 2-pin connector holds the detachable cable. It is listed from $19.99, with 8 orderable options in total.

Options and pricing

The 8 orderable options pair two color options, Aureus and Abyssia, with four connectivity choices. 3.5 mm is $19.99, 3.5mm With Mic and 4.4 mm are each $20.99, and Type-C with Mic is $22.99. The page text names the same color options and lists 3.5mm with or without microphone, 4.4mm balanced and USB Type-C terminations.

How it compares

The CCA Polaris Pro starts at $19.90, the TRN Dolphin at the same $19.99 and the Moondrop Chu II at $19.54. The Kira's range runs to $22.99 for the Type-C with Mic option, and its listing names Aureus and Abyssia color options.

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.

What we couldn’t verify

  • The page's tuning and sound descriptions (balanced, natural, warm vocals, smooth treble, soundstage, instrument separation) are the maker's claims and were not checked here.
  • The page says the cable is silver-plated and braided, but the listing text gives no conductor details or cable length.
  • The page gives the Kira no impedance or sensitivity rating, and its cable length is not stated either.
  • 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.
