ROSESELSA CJ20 Planar IEMs Review

A single 14.2mm planar magnetic driver sits in each all-metal shell of the ROSESELSA CJ20, which the page says was co-tuned with Andy Audio Vault for rock and metal. It is listed at $169. The specification section gives 24Ω±10%, 102±3dB and 20Hz~20kHz, with 0.78mm 2-pin connectors and a modular 3.5mm and 4.4mm plug system.

Specifications

Options and pricing

One option, named CJ20, is listed at $169 and was orderable when the page was read. The page says it comes with two eartip types that differ in bore size, and that the cable has swappable 3.5mm and 4.4mm termination plugs. Each shell weighs 5.4 grams per the page, and the page text gives no ear tip sizes, case or cable length.

How it compares

The Kinera Celest Phoenixcall 2.0 2DD + 2BA + 2 Planar Drivers IEMs cost $169 as well and list two dynamic, two balanced armature and two planar drivers in the name, where the CJ20's name lists one 14.2mm planar magnetic driver. The TWISTURA Woodnote 10mm Wood Diaphragm Dynamic Driver IEMs are $159.90 with a 10mm wood diaphragm dynamic driver, and the Softears Studio2 2BA In-Ear Earphone is $159 with two balanced armatures in the name. The CJ20 suits buyers who want a planar driver; the other two suit buyers who want a dynamic or armature design.

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.
