FiiO FP3 Planar IEMs Review

Per the page, FiiO's FP3 is built around a self-developed second-generation 14.5mm planar magnetic driver with a 1um diaphragm, and the page lists it at $89.99. The specification section gives 36Ω@1kHz, 105dB/mW and 10Hz-40kHz, and the cable uses 0.78mm 2-pin connectors. Per the page, 14 N52 neodymium magnets sit seven on each side of the driver and each earpiece weighs 6.5 grams.

Specifications

Options and pricing

The wooden face cover sets the two options apart, FP3 Rosewood-3.5mm and FP3 Black walnut-3.5mm at $89.99 each, both orderable when the page was read. Both names carry 3.5mm. The features list a single 3.5mm plug, yet the cable text says 3.5mm single-ended and 4.4mm balanced plugs are in the package, so the page does not settle which plugs each option holds.

How it compares

The Fosi Audio IM4 10mm Dual-Cavity Dynamic Driver IEMs are $93.34 and their spec line names a dual-magnetic, dual-cavity dynamic driver, while the Moondrop Rays 1DD+1 Planar Drivers Gaming IEMs are $99.99 and name one dynamic and one planar driver. The FP3 is $89.99 with a 14.5mm planar driver and a stated 36Ω and 105dB/mW. It suits buyers who want a planar IEM at this price; the sibling summaries here do not state their impedance or plugs.

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.

FiiO's own notice "A letter to FiiO fans" (undated) lists HiFiGo among sellers it has not authorized and recommends buying FiiO products from local agents. FiiO says it still services genuine products bought from such sellers if the buyer emails [email protected], but the buyer pays the freight and duties if a unit must go back to 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.
