Unique Melody MEXT IEMs Review

Unique Melody's MEXT puts six drivers in each earpiece: a coil-based bone conduction driver, one dynamic driver and four balanced armatures, arranged in a four-way crossover, and the page lists it at $999. The specification section gives 16Ω, 108dB@1kHz, 20Hz-23kHz for the dynamic and armature drivers and 200Hz-7kHz for the bone conduction driver. The page says the cable is a custom PW Audio copper cable whose termination is chosen while buying.

Specifications

Options and pricing

The store's option field is named Size and lists 2.5MM, 3.5MM and 4.4MM, each at $999 and orderable when the page was read. The page text says the cable is a custom PW Audio copper cable and that its termination is chosen while buying the pair, so the three options read as plug sizes; the feature list calls the cable a UM Copper M1 custom cable. The page text gives no earpiece connector type, cable length or box list.

How it compares

The Effect Audio Perseus is the same $999 and its title lists 2DD + 2BA + 4MPD + 1BC drivers. The Softears SE6LIVE is $1,100 with 6 BA drivers, and the FiiO FA19 is $999.99 with 10 BA drivers from Knowles, per their listings. The MEXT suits buyers who want a bone conduction driver and a choice of plug sizes at $999; the SE6LIVE and the FA19, each named for balanced armature drivers, suit those who want armatures.

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.
