SIVGA P2 PRO Planar Headphones Review

Listed at $449, the SIVGA P2 PRO is a planar magnetic, open-back, over-ear headphone with Red Oak wood ear cups. The page gives 32Ω±15% impedance, 98±3dB sensitivity, a 20Hz-40kHz range and a weight of 435 grams, and says the detachable 6N OCC copper cable ends in a 4.4mm termination. It describes a large planar driver and a Sapphire Vibration Circuit but never states the driver's diameter.

Specifications

Options and pricing

The page lists a single option, P2 PRO, at $449, orderable when it was read. The specification gives the termination as 4.4mm only, and the page names no adapter or second cable, so a source without a 4.4mm output needs something the page does not mention.

How it compares

The FiiO FT15 101mm Planar Magnetic Open-Back Headphones cost $490.99 and the Moondrop PARA 2 100mm Planar Driver Headphone costs $499.99, against $449 here; both name a driver size, 101mm or 100mm, while the P2 PRO page gives none. The DUNU Mortise 50mm Dynamic Driver Open-Back Headphones cost $429.99 and use a dynamic driver. The P2 PRO suits a buyer who wants a planar at the lowest of the three planar prices; the FT15 and PARA 2 suit those who want a stated driver size.

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.
