HiBy FD5 Desktop DAC/Headphone Amp Review

The page lists the HiBy FD5, a desktop DAC and headphone amplifier, at $429 as a single option. The footer of two pictures describes a multifunction desktop headphone amplifier with USB and Bluetooth input, independent 3.5mm and 4.4mm headphone outputs and line outputs, and one picture says it supports up to PCM 32/768 and DSD512. The page title names AK4493*4 as the DAC, which those pictures do not confirm.

Specifications

Options and pricing

A single option is listed, FD5, at $429 and orderable when the page was read, so no color or plug choice is offered. Only two of the page's 20 pictures were available for this review, and neither gives an in-the-box list, so what comes with the unit is not confirmed here.

How it compares

The xDuoo XD05T Dual ES9039Q2M Portable DAC & Headphone Amplifier costs $549 against $429 here and is named a portable unit with dual ES9039Q2M chips, while the FD5 is named a desktop DAC and headphone amp. The xDuoo XD05 BASIC2 CS43131 Portable DAC & Headphone Amplifier and the iBasso Nunchaku Dual CS43198 USB DAC & Tube AMP are $299 each. The FD5 suits a fixed desk setup; the two xDuoo units are named portable.

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.
