DUNU S&S Pro Silicone Eartips Review
DUNU S&S Pro are silicone ear tips, pictured as straight-wall, at $13.90 per 3-pair option in S, M, L, XL or SML, with a pictured size table and a nozzle fit of 4.6 - 6.5 mm. A pictured box list adds a storage case. They suit owners who want printed dimensions for each size.
Our verdict
A fit for owners of earphones with a nozzle in the pictured 4.6 - 6.5 mm range who want a size table, a choice of S, M, L or XL and a storage case in the box. Look elsewhere if you need a text specification list, a stated size split for each 3-pair set or any proof behind the material and sound-channel statements. The spec figures come only from pictures, and an independent test of this model was not among the sources checked for this review.
- Best for
- Owners of earphones with a 4.6mm-6.5mm nozzle, the range the pictured table lists, who want a size table and a storage case.
- Skip if
- You need a stated size split for the 3 pairs or text specifications rather than pictures.
Why 3.3/5: Held back by a description that is pictures only, with no specification list as text and its claims in pictures, by the store's own terms that contradict each other, and by figures no independent test was checked for.
The DUNU S&S Pro, pictured as Stage & Studio and as straight-wall tips, is a set of silicone ear tips listed at $13.90 for 4.6mm-6.5mm nozzles. The description is pictures only, so the figures come from those pictures: a size table with a 4.48mm bore for every size, outer diameters from 8.98mm to 13mm across S, M, L and XL, and a box list of 3 pairs plus a storage case. Material, sound-channel and durability statements in the pictures are claims, not measurements.

Options and pricing
Five options are listed at $13.90 each and all were orderable when the page was read: S&S Pro S, M, L and XL, plus S&S Pro SML, each named 3 Pairs. A picture lists '3 pairs of ear tips' and 'Storage case included' as the box contents, but the pictures read do not say whether the 3 pairs are one size or mixed, and they do not describe what the SML option holds.
How it compares
The SHANLING SE100 Silicone Eartips For 4.9-6.5mm Nozzle is $9.90 for a 4.9-6.5mm range against $13.90 and 4.6mm-6.5mm here, and the JUZEAR x Z Reviews Render Pro Eartips For 4.6-5.5mm Nozzle is $14.99 for 4.6-5.5mm. The FiiO HS19 Silicone Replacement Eartips (12 Pairs) is $12.99 for 12 pairs. The S&S Pro suits owners who want a printed size table and a storage case in one set; the HS19 suits those who want many pairs to try.
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 excludes carrying cases, ear tips and other accessories, and a note on its return page excludes ear tips (earplugs) and holsters from returns for hygiene reasons, so treat these as final sales once opened. Questions 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 pictured table gives bore, outer diameter and height for all four sizes (S, M, L, XL)
- A picture lists a storage case in the box along with 3 pairs of tips
- The nozzle fit is printed as 4.6 - 6.5 mm in the pictured table and matches the store title
- All five options are priced at $13.90 and were orderable when the page was read
Worth noting
- The description is pictures only, so every spec figure comes from them, and three of the page's nine pictures were not opened at full size for this review
- The pictures read do not say whether the 3 pairs are one size or mixed, or what the SML option holds
- Material, sound-channel and durability statements in the pictures are claims with no certificate or measurement shown in the pictures read
Questions before you buy
What nozzle size does the DUNU S&S Pro list?
The store title gives 4.6mm-6.5mm, and the pictured dimensions table says 'Fits Nozzles: 4.6 - 6.5 mm'. The same table lists a 4.48mm bore for every size.

What comes in each option?
Each option is named 3 Pairs, and a picture lists '3 pairs of ear tips' and 'Storage case included'. The pictures read do not say whether the 3 pairs are one size or mixed.
Where does HiFiGO ship from, and how long does it take?
From its warehouse in China, usually 1-3 business days after the order. The shipping policy gives 1-2 weeks to the US by Priority (6-10 days by Premium), both with duties and taxes prepaid, 2-3 weeks to Canada, 1-2 weeks to the UK and 10-15 days to Australia. Express couriers take 3-7 days, but the buyer pays any duties.
Can I send it back if I change my mind?
HiFiGO gives 7 days to report an item that arrives dead, damaged or wrong. Its policy also describes 30-day returns, but requests 7 to 30 days after delivery lose 30% of the MSRP plus shipping both ways and duties, and the FAQ on the same page says no refund or exchange after 7 days. Ask [email protected] before you open the box.
Is there a warranty on accessories like this?
No. HiFiGO's warranty excludes carrying cases, ear tips and other accessories, and its return page excludes ear tips and holsters for hygiene reasons.

What we couldn’t verify

- The pictures read do not say whether each 3-pair set is one size or mixed, or what the SML option holds. Three of the nine pictures (feature panels) were not opened at full size, so their text is not covered.
- The dimensions come from one pictured table; no independent test or measurement of the tips was checked for this review.
