SIVGA Luan Open-Back Headphones Review

Open-back and wood-cupped, the SIVGA Luan pairs a 50mm dynamic driver with a nickel-coated composite carbon diaphragm and is listed at $359 in Black or Brown. The page gives 38Ω, 100dB, a 20Hz-40kHz range and a weight of 354grams, and lists a detachable cable with a 3.5mm connector and a leather case. SIVGA describes deep bass and a smooth midrange; those are the maker's words, with no outside measurement checked for this review.

Specifications

Options and pricing

Black and Brown are both listed at $359 and both orderable when the page was read. The page lists a detachable cable with a 3.5mm connector, which it says makes the headphone compatible with other cables, and mentions a TPU rubber coating on the stock cable. It does not say which plug sits at the source end, and it names no balanced cable and no adapter.

How it compares

The DUNU Mortise 50mm Dynamic Driver Open-Back Headphones also use a 50mm dynamic driver and cost $429.99 against $359 here, with a carbon fiber diaphragm named in their summary line. The SIVGA SV023 Open Back Walnut Wooden Dynamic Driver Headphone is the same maker's walnut-cup model at $499. The Luan suits a buyer who wants wooden cups at the lowest of the three prices; the others suit buyers who want their named materials.

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.
