DUNU Hulk Pro Mini SA6 Ultra Cable Review
A 26AWG, 4-wire Litz Type 2 earphone cable of Furukawa single-crystal copper, listed from $199.99 with MMCX or 2Pin 0.78mm connectors and a 3.5mm+2.5mm+4.4mm plug set. The page describes a swappable plug system, and two options add Type C to the set.
Our verdict
Suits buyers who want a 26AWG Furukawa single-crystal copper cable with the page's swappable 2.5mm, 3.5mm and 4.4mm plug set and MMCX or 2Pin 0.78mm connectors, from $199.99. Look elsewhere if you need a stated cable length or weight, or an explanation of the Type C option. The main caveat is that the page's weight, sound and build statements are claims with no measurements behind them.
- Best for
- Buyers who want the page's swappable 2.5mm, 3.5mm and 4.4mm plug system on a 26AWG Furukawa copper cable.
- Skip if
- You need a stated cable length, a stated weight or an explained Type C option.
Why 3.4/5: Held back by a specification section written as prose with no cable length or stated weight, by the store's own terms contradicting each other, and by figures that are the store's own with no independent test checked.
DUNU's Hulk Pro Mini is a Furukawa single-crystal copper earphone cable, listed from $199.99 with MMCX or 2Pin 0.78mm connectors. The page lists a Litz Type 2 braided structure, a 4-wire strand configuration, 26AWG wire diameter and an independent aluminum foil shielding layer on each strand. It describes DUNU's Q-Lock Plus swappable termination plug system, with 2.5mm balanced, 3.5mm single-ended and 4.4mm balanced plugs said to be in the package.

Options and pricing
Four options pair a connector, MMCX or 2Pin 0.78mm, with a plug set. With the 3.5mm+2.5mm+4.4mm set each is $199.99; with 3.5mm+2.5mm+4.4mm+Type C each is $219.99. All four were orderable when the page was read. The page text describes only the 2.5mm, 3.5mm and 4.4mm termination plugs, so what the Type C addition is stays unstated there.
How it compares
The HAKUGEI Dark Night God Litz 6N OCC Copper Earphone Cable is $195 and its title names 2.5/3.5/4.4 plugs with 2Pin 0.78 or MMCX, against $199.99 here for a 3.5mm+2.5mm+4.4mm plug set. The Effect Audio Signature Series Cadmus Lite 4 Wires Earphone Cable is $149 at 24AWG 4 Wires, and the Effect Audio Signature Series II Ares S II x Cadmus II (A x C II) Earphone Cable is from $249.90 at 26AWG 8-Wire. The Hulk Pro Mini lists 26AWG and a 4-wire strand configuration, and suits buyers who want the swappable plug set the page describes.
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.
What we liked
- The page names Furukawa single-crystal copper in a Litz Type 2 braided structure at 26AWG
- An independent aluminum foil shielding layer on each strand is listed
- The page describes a Q-Lock Plus swappable termination plug system, with 2.5mm, 3.5mm and 4.4mm plugs said to be in the package
- MMCX and 2Pin 0.78mm connector options cost the same $199.99 with the base plug set
Worth noting
- The page text gives no cable length or stated weight; it says weight is reduced by up to 40% without a base figure
- The option names add Type C for $219.99, but the page text describes only the three termination plugs
- Build and sound statements on the page (robust, lighter, improved technicalities) come with no figures
