KINERA NANNA 2.0 Pro Electrostatic IEMs Review

KINERA's NANNA 2.0 Pro is a quad-driver tribrid IEM whose spec line gives 1DD+1BA+2EST; the page text names a 7mm dynamic driver, one Sonion balanced armature and two Sonion electrostatic drivers on each side. HiFiGO lists it at $799 with a silver 4.4mm cable and adapters to 2.5mm and 3.5mm. The page gives 60Ω, 110dB and a 5Hz-50kHz range, and says the face covers are hand-painted.

Specifications

Options and pricing

One option is listed, named Blue Nanna 2.0 Pro with a silver 4.4mm cable and adapters to 2.5mm and 3.5mm, at $799 and orderable when the page was read. The page shows a crossed-out price of $949 next to $799. The accessory text also lists a black leather carry case, a set of ear tips and more. Separately, the page says customizing is available from a copy of the ear mold; the page text gives no price for customizing.

How it compares

The Unique Melody Stardust is also $799 and its name counts 2DD + 4BA hybrid drivers. The Moondrop Armature Art 12 is $799.99 and its name counts 12 balanced armature drivers. The Moondrop ILLUSTRIOUS is $899 with an 11mm dynamic driver in its name. Choose the NANNA 2.0 Pro for electrostatic drivers alongside one armature and one dynamic driver, plus 2.5mm and 3.5mm adapters in the option; the others suit buyers who want more dynamic drivers, an all-armature set or an 11mm dynamic driver.

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.
