Celest x CVJ Iris In-Ear Monitors Review
Sold under the Celest x CVJ name, this IEM has a single 10mm LCP diaphragm dynamic driver and a 4-core silver-plated cable, per the page. It costs $39 in a Clear or Purple shell, and suits buyers who want an inline 3-button remote with a microphone rated at 42+/-3dB sensitivity.

Our verdict
A single-driver IEM for someone who wants a 10mm LCP diaphragm, a Clear or Purple shell and an inline controller with a microphone at $39. Look elsewhere if you need a listed impedance or earphone sensitivity, or a clear connector choice, since the listing text gives no impedance and the options show only colors. The main caveat is that the sound and diaphragm statements are the maker's own claims and were not checked here.
- Best for
- Those who want a single-driver IEM with a Clear or Purple shell and an inline 3-button controller with a microphone.
- Skip if
- You need a listed impedance or earphone sensitivity, or a clear choice of 3.5mm or Type-C connector.
The Celest x CVJ Iris pairs a single 10mm LCP (Liquid Crystal Polymer) diaphragm dynamic driver with a shell the page calls 4D crystal casting, offered in Clear or Purple. The cable uses low-resistance alloy copper silver-plated conductors in a 4-core, 156-strand braid with a soft PVC jacket, per the page. An inline 3-button controller and a microphone are listed. The price is $39 for both colors.
Options and pricing
There are two orderable options, Clear and Purple, and both cost $39. The page text also says the cable comes with standard 3.5mm or Type-C connectors, yet the orderable options show only the two colors, so the listing does not make clear how to choose a connector. The listing text gives no further information on the Type-C connector.
How it compares
The Iris is $39, the same starting price as the Shanling MG20, whose entry shows no spec lines, and just above the SIMGOT EW200 at $38.25, whose entry mentions hybrid. The CCA Pianist is $39.99 and its entry mentions 1DD, 2BA and hybrid, while the Iris's page lists a single 10mm dynamic 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.

What we liked
- The page lists a single 10mm LCP diaphragm dynamic driver
- The cable construction is described as a 4-core, 156-strand braid with a PVC jacket
- A 3-button inline controller and an omnidirectional microphone are listed, with a 42+/-3dB figure for the microphone
- Both colors, Clear and Purple, cost the same $39
Worth noting
- The listing text gives no impedance, earphone sensitivity, frequency response or cable length
- The page mentions 3.5mm or Type-C connectors, but the options show only color, so the connector choice is unclear
- The page's description of the diaphragm and sound is the maker's wording and was not checked here

What we couldn’t verify
- Per the page, the listing text gives no impedance, earphone sensitivity, frequency response or cable length; the 42+/-3dB figure is for the microphone.
- The page's claims about the LCP diaphragm, transient response and balance are the maker's own claims and were not checked here.
- The page mentions 3.5mm or Type-C connector options while the options list only colors, and its cable winding figures (250.06 winding + 140.06 per core) read oddly and were not used.
- 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.
