Moondrop Echo-B 4.4mm DAC/Amp Review

Moondrop's Echo-B takes a USB Type-C input and outputs through a fully balanced 4.4mm jack, and the store lists it at $24.99. The page credits it with a custom-developed fully balanced decoding chipset, PCM up to 32-bit/384kHz, a 117dB(A-Weighted) SNR, a 120dB(A-Weighted) dynamic range and 0.001% THD+N at no load. It also describes five built-in tuning configurations, plus other setups and parametric EQ through the Moondrop Link application.

Specifications

Options and pricing

The page lists a single option, Echo-B, at $24.99, shown as orderable when it was read. The spec section lists one headphone jack, the 4.4mm balanced one, so the page text offers no 3.5mm choice on this model; the 3.5mm model is the separate Echo-A. The page text lists no cable, case or box contents.

How it compares

The Moondrop Echo-A costs $21.99 against $24.99 here and uses a 3.5mm jack, so it fits 3.5mm single-ended plugs. The MuseHiFi U3 is $29.99 and its listing line mentions a fully-discrete OPAMP filter design. The Moondrop Dawn Pro 2 is $59.99, names dual CS43198 chips and lists Native DSD256 beside 32-Bit/384kHz PCM, where the Echo-B page text lists PCM only. The Echo-B suits a 4.4mm-only budget setup; the Dawn Pro 2 suits buyers who want DSD.

Shipping, returns and warranty

HiFiGO sells from hifigo.com and says every order leaves its warehouse in China, usually 1-3 business days after it is placed, and says its delivery times are estimates, not promises. Its shipping policy gives the United States 1-2 weeks (about 10 days on average) by Priority and 6-10 days by Premium, both with duties and taxes prepaid by the store; Canada 2-3 weeks; the United Kingdom 1-2 weeks; and Australia 10-15 days. Express couriers (DHL, UPS, FedEx) take 3-7 days, but then the buyer pays any duties and taxes. No shipping page names New Zealand, PO boxes are not accepted, and the free-shipping thresholds differ between the store's own pages, so check the cart. One of its two shipping pages adds that a lost parcel on an order above $50 gets only a 50% refund. A US buyer reported a $40 tariff charge in August 2025, after which HiFiGO said it had added a customs notice at checkout.

Read the return terms before you order. The homepage advertises 7-day returns. Both of HiFiGO's policy pages offer a 7-day dead-on-arrival cover (a replacement or a full refund, with the return postage refunded) and also describe 30-day returns, but a request made 7 to 30 days after delivery loses 30% of the MSRP as a restocking fee (10% more if the packaging is incomplete), plus shipping both ways and duties, and the FAQ on the same pages says there is no refund or exchange once 7 days have passed. One version recommends reselling an opened product locally. Custom IEMs and custom cables cannot be returned, no return address is published, and buyers describe sending items back to China.

HiFiGO's warranty runs one year from the order date for parts and labor; its policy names desktop DACs and amps, IEMs and dongles at one year and gives cables and adapters three months. HiFiGO decides between repair and replacement, the buyer pays the shipping, and faulty items go back for service, not for a refund. Claims go to [email protected], the only contact the store lists: its pages name no company, street address or phone, and its terms are governed by the laws of China.

On Trustpilot, HiFiGO had 4.6 out of 5 from 378 reviews when we checked on 2026-10-28 (91% five-star, 5% one-star), and it had replied to about 75% of negative reviews; Trustpilot notes the store has not invited customers to review recently. The one-star reviews mostly concern the short return window and the deductions on returns, items listed in stock that turned out back-ordered, slow email support and a tariff charge on a US delivery in 2025. HiFiGO says its products are genuine and come in the brands' retail packaging; it does not claim to be an authorized dealer.
