Our verdict

Suits buyers who want a named Ultrapure 8N OCC conductor with a choice of 2.5mm, 3.5mm or 4.4mm plugs and MMCX or 2pin connectors, starting at $136.99. Look elsewhere if you need a stated wire gauge, strand count or compatibility list. The caveat is that every spec figure is read from the store's pictures, and the sound claims in them carry no figures.

Best for
Buyers who want an Ultrapure 8N OCC cable in a 2.5mm, 3.5mm or 4.4mm plug with MMCX or 2pin connectors.
Skip if
You need a stated wire gauge, strand count or list of compatible earphones.

Why 3.3/5: Pulled down by short page text with no specification list, since its claims sit in pictures; the store's own terms contradict each other, and every figure is the store's own with no independent test checked for this review.

NICEHCK's AceOrpheus is an earphone cable whose pictured specifications give an Ultrapure 8N OCC conductor, a length of about 1.2m and an aluminium alloy plug shell and splitter. The listing starts at $136.99 and has seven options: 2.5mm, 3.5mm or 4.4mm plugs to MMCX or 2pin, plus a 4.4mm to PentaconnEar version. The pictures read for this review give no wire gauge, strand count or core count.

Options and pricing

Seven options are listed, all orderable when the page was read. The 3.5mm cables to MMCX or 2pin are $136.99, the 2.5mm cables to MMCX or 2pin are $137.99, the 4.4mm cables to MMCX or 2pin are $139.99, and the 4.4mm to PentaconnEar cable is $149.99. The plug sizes come from the option names, since the pictures read give no plug size. The pictures read for this review give no in-the-box list.

How it compares

The NiceHCK DualDragon 8N OCC+Microalloy Dual Plugs Earphone Cable starts at the same $136.99 and its spec reads Conductor: 8N OCC+Microalloy CVD Graphene, against Ultrapure 8N OCC here. The Moondrop Atami Single Crystal Copper + Silver Solder Litz Structure Earphone Upgrade Cable is from $129.99 and its name gives single crystal copper with silver solder in a Litz structure. The AceOrpheus suits buyers who want to pick a 2.5mm, 3.5mm or 4.4mm plug in the option names; the DualDragon suits buyers drawn to the dual plugs in its name.

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.

Cables and adapters get three months of warranty from the order date, against one year for DACs, amps and IEMs; a note on the same page also excludes cables from returns for hygiene reasons, while the FAQ says a cable can come back in its original condition. HiFiGO decides between repair and replacement and the buyer pays the shipping. Claims go to [email protected], the only contact the store lists: its pages name no company, street address or phone.

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.

Can I send it back if I change my mind?
