KZ AN01 Wireless Earhook Review
A wireless earhook from KZ that the page says turns wired earphones into wireless ones, listed at $36 as a single option. The page lists LDAC at up to 990 kbps, a charging case with a 400mAh battery and a 0.75mm connector for KZ and other 2-pin earphones.

Our verdict
A fit for someone who already owns wired earphones with a 2-pin connector and wants to try a Bluetooth earhook at $36, with LDAC, ANC and a 400mAh charging case as listed. Look elsewhere if you want a finished set of earphones, or if you need a Bluetooth version, a latency figure or an earhook weight, since the listing text gives none of them. The main caveat is that the sound, latency and ANC descriptions are the maker's own words and were not checked here.
- Best for
- Someone with wired 2-pin earphones who wants to add Bluetooth with LDAC and ANC as listed.
- Skip if
- You want a finished set of earphones or need a stated Bluetooth version.
KZ's AN01 is what the page calls a wireless earhook that upgrades wired earphones into wireless ones, with the Bluetooth parts housed outside the earbuds. It lists LDAC at up to 990 kbps, ANC with four microphones and a transparency mode, and a charging case with a 400mAh battery. The price is $36, and the store shows one orderable option.
Options and pricing
The store lists one orderable option at $36, so there is no color, plug or bundle choice to compare. The page names a 0.75mm gold-plated connector and says it fits most KZ earphones and other 2-pin models, so check that your earphones use that connector before ordering. The listing text gives no cable length, no weight and no Bluetooth version.
How it compares
The KZ Carol Pro costs $32.99 and its listing text mentions Bluetooth 5.4, while the AN01 costs $36 and its listing text gives LDAC at up to 990 kbps but no Bluetooth version. The ROSE TECHNICS Ceramics is $29.99 with Bluetooth 5.3 mentioned in its listing text, and the Moondrop PILL is $42.49 with no spec noted in its summary.
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 lists LDAC at up to 990 kbps and a charging case with a 400mAh battery
- ANC with four microphones and a transparency mode are listed, per the page
- The 0.75mm gold-plated connector is said to fit most KZ earphones and other 2-pin models
- The page names four modes: Gaming, Standard, ANC and Transparency
- One orderable option at $36, so the price does not change by choice
Worth noting
- The listing text gives no Bluetooth version, no earhook weight and no latency figure for the gaming mode
- It is an add-on for wired earphones with a 2-pin connector, so it needs earphones that fit the connector
- The lossless, ultra-low latency and wired-like sound statements are the maker's wording and cannot be checked from the listing

What we couldn’t verify
- The page's sound and latency descriptions (lossless, wired-like sound, ultra-low latency, balanced frequency response) are the maker's claims and were not checked here.
- Per the page, the 40 hours of listening and the 990 kbps figure come with no test conditions, and the listing text gives no Bluetooth version, latency figure or weight.
- 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.
