TANGZU NeZha In-Ear Monitors Review
An in-ear monitor from TANGZU that the page describes as its first full-body resin model, with custom balanced armature, Sonion subwoofer and EST drivers. It suits buyers who want a resin-body set with a Q-IAO crossover, at $359.10 in the UIEM style.

Our verdict
An in-ear monitor for someone who wants a resin-body set with named driver types (custom BA, Sonion BA subwoofer, EST and piezoelectric) at $359.10. Look elsewhere if you need driver counts, impedance, sensitivity, or any cable or plug details, since the listing text gives none. The main caveat is that the crossover and sound claims are the maker's wording and none of them could be checked here.
- Best for
- Someone who wants a full-resin-body IEM with named custom BA, Sonion and EST drivers.
- Skip if
- You need driver counts, impedance or cable and plug details stated on the page before you buy.
TANGZU presents the NeZha as its first full-body resin in-ear monitor, and the page names custom balanced armature drivers, Sonion balanced armature subwoofer drivers and EST drivers, plus high-precision piezoelectric drivers, without giving a count for any of them. A crossover called Q-IAO is listed, the body is medical grade resin, and the single option is priced at $359.10 in the UIEM style.
Options and pricing
One orderable option is listed, Style UIEM, at $359.10. The specs row also names CIEM, but the options show only the UIEM style, so the listing text does not make clear whether a second style is offered. The page shows $399 crossed out beside the price, which is the store's own comparison and not something we checked. No color or plug choice is listed.
How it compares
The THIEAUDIO Hype 4 MKII costs the same $359.10, and the INAWAKEN Twilight-DS starts at $349. The CVJ MYTHERA is $368 and its listing text mentions Hybrid and planar, where the NeZha's page names piezoelectric and EST drivers instead. The NeZha itself is $359.10 for its single orderable option.
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 names the driver types: custom BA, Sonion BA subwoofer, EST and piezoelectric
- A full resin body is described, with hand-layered metal flakes and gold-plated aluminum plates
- A crossover design called Q-IAO is named
- One option at a stated price, $359.10, with the style (UIEM) shown
Worth noting
- The listing text gives no driver counts, impedance, sensitivity or frequency response
- The listing text gives no cable, connector or plug details
- The specs row names UIEM and CIEM but only UIEM is orderable, which leaves the second style unclear
- The page's sound and crossover claims are the maker's wording and cannot be checked from the listing

What we couldn’t verify
- The page's sound descriptions (harmony, precision, dynamics and detail) are the maker's claims and were not checked here.
- The page claims the Q-IAO crossover allocates more audio bands to each driver than any available crossover, a maker claim that was not checked here.
- The listing text gives no driver counts, impedance, sensitivity, frequency response, cable length or plug type, and the specs row names CIEM while the options show only UIEM.
- 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.
