TOPPING E50II DAC Review
A DAC from TOPPING with an AKM AK4497S chip, USB, optical and Bluetooth inputs and RCA and TRS balanced outputs, listed at $169.15 in White, Black or Silver. The page lists USB PCM up to 768 kHz and DSD512, and shows $199.00 crossed out.

Our verdict
Look at the E50II if you want a DAC with USB, optical and Bluetooth inputs, RCA and TRS balanced outputs and an app at $169.15. Skip it if you need output level or distortion figures, since the listing text gives none. The main caveat is that the page's sound words (rich textures, detailed layering, deep bass) are the maker's claims and were not checked here.
- Best for
- Someone who wants a DAC with USB, optical and Bluetooth inputs, balanced outputs and an app for control.
- Skip if
- You need output level, distortion or signal-to-noise figures before buying.
TOPPING's E50II is a DAC built around an AKM AK4497S chip, with USB input listed for PCM 44.1 kHz-768 kHz (16-32 bit) and native DSD64-DSD512 and a dual-format optical input for S/PDIF and ADAT. Per the page it also takes Bluetooth through a Qualcomm QCC5125, sends signal out through RCA and TRS balanced outputs and can be controlled from the TOPPING Home app. It is listed at $169.15 with three options, White, Black and Silver.
Options and pricing
White, Black and Silver are the three options, all $169.15. The page shows $199.00 crossed out beside the price, which is the store's own comparison and one we did not check. The text mentions touch-sensitive controls, adjustable screen brightness and custom drivers for Windows with plug-and-play macOS support, but it does not list what comes in the box.
How it compares
The Shanling H2 is $169 and its listing text mentions a CS43198 chip, and the SMSL D-6S is $169.99 with ES9039Q2M and Bluetooth 5.1 mentioned. The xDuoo XA-02 is the same $169.15 as the E50II, and its spec line shows output power figures rather than a chip. The E50II lists AK4497S at $169.15 with Bluetooth through a QCC5125.
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 couldn’t verify
- The page says rich textures, detailed layering and deep bass; these are the maker's claims and were not checked here.
- The listing text gives no output level, distortion, signal-to-noise or dynamic range figures, weight or dimensions, per the page.
- The $199.00 crossed out beside the price is the store's own comparison per the page and was not checked here.
- 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.
