xDuoo MX-C1 Bluetooth 5.4 Audio Device Review
A small Bluetooth 5.4 audio device from xDuoo that the page calls battery-free, with a 3g body and plug-and-play use. It suits a buyer who wants LE Audio formats (LC3 and aptX Lite) at $33.92 and accepts that the listing text names no connector or DAC chip.

Our verdict
A low-priced Bluetooth 5.4 device for someone who wants LE Audio and aptX format support in a 3g battery-free body, per the page, at $33.92. Buyers who need a stated connector, DAC chip, input and output list or sample rates should look at another listing, because this one gives none of them. Treat every figure, including the 20ms latency, as the maker's claim; none of it was checked here.
- Best for
- Someone who wants a small, battery-free Bluetooth 5.4 device with LE Audio and aptX formats at a low listed price.
- Skip if
- You need a stated DAC chip, input and output list or sample rates, because the listing text gives none.
The xDuoo MX-C1 is a Bluetooth 5.4 device that the page describes as battery-free, with a 3g body and plug-and-play setup. It uses a Qualcomm Bluetooth chip, and the page lists LE Audio formats (LC3 and aptX Lite) together with aptX AD, aptX HD, aptX and aptX Lossless, plus latency as low as 20ms. One option is listed, at $33.92.
Options and pricing
There is one orderable option, priced at $33.92, so there is no color, plug or bundle choice to make. A crossed-out $39.90 appears beside the price on the page; that is the store's own comparison and we did not check it. The listing text does not say which connector the device uses, so confirm it suits your phone, PC or console before ordering.
How it compares
The xDuoo XQ50 Pro 2 costs $75.65 and its entry mentions Bluetooth 5.1 and ES9018K2M, while the MX-C1 lists Bluetooth 5.4 at $33.92 and names no DAC chip. The SMSL R1 is $66.23 and the TRN TE PRO is $81.59 with CS43198 mentioned, so both sit above this price.
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).
- Large items. The page says headphones and desktop DAC/AMPs count as large items, for which Express is free only for orders over $499.99.
- 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 Bluetooth 5.4 with a Qualcomm Bluetooth chip

- The page describes a 3g body with a battery-free design
- Listed at $33.92, under every sibling shown here (from $66.23)
Worth noting
- The listing text gives no connector type, so fit with a given phone, PC or console cannot be confirmed from it
- The listing text gives no DAC chip, inputs, outputs or sample rates
- The page gives no range or power-draw figure, and its 20ms latency is an "as low as" claim

What we couldn’t verify
- The page says the sound quality is comparable to wired connections and that connections are more stable with longer range and lower latency; these come from the maker and were not verified here.
- The page says nothing about the connector, and the listing text gives no DAC chip, inputs, outputs or sample rates; it also does not say whether the unit sends or receives Bluetooth audio.
- 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.
