| 10 mm Driver |
🎧 We are reviewing the UiiSii C200 a small and lightweight earphone that UiiSii labels as “Fighting Bird” and designed their housings as the head of a bird. The UiiSii C200 looks exactly the same as the Rock Y1, whether if they are the exact same earphone that Rock decided to rebrand or not we cannot assure it but it is possible that they are the same earphone. UiiSii is a brand that designs very original earphones with ultra budget prices and, many times, full packed features. The UiiSii C200 is part of their most economic line of earphones and sits right above the UiiSii C100. They might not have most fancy technical specs with a single dynamic driver but it’s size is a bit larger than average measuring 10 mm. The housings of the UiiSii C200 are made of plastic and are ultra lightweight and their nozzles are angled providing a deep and secure fit. The cables are very rubberized and rounded with great anti-tangling performance. In comparison to many average earphones the main part of the cable is very thick, the cables after the bifurcation become much thinner but within normal girth. Inline a microphone and 1-button control is found which allows you to play/pause music, skip songs and answer/reject calls; the mic/control has a compatibility switch for iOS and Android devices. You can buy the UiiSii C200 in a wide variety of colors: black, white, pink, red or green.

Accessories & Packaging
The UiiSii C200 come in a simple box with 2 extra pair of eartips.
Bass & Sub Bass
The UiiSii C200 offers punchy and deep bass right out of the box with fun and energetic sound able to cover any music type and still their bass does not sound overdone. With an EQ their bass becomes much deeper and punchier but may start to sound boomy. Running the UiiSii C200 through our extreme bass tests amplifying with a Fiio E12 Mont Blanc set to high gain, bass boost ON and applying a custom basshead EQ; the C200 were able to take up to 48% of Fiio’s maximum power. The results were a great increase of punch and depth that remained free of distortion but could not reach a basshead impact and rumble like the UiiSii HM7 or the spectacular Pioneer SE-CX8 and Sony MDR-7550/800ST.

Mids & Vocals
Mids are very warm and somewhat recessed lower mids make lower vocals a bit laid back but not muddy or lifeless; higher mids usually do not sound harsh. For non-audiophile listeners, the mids of the UiiSii C200 will be, smooth, pleasant and very good. An EQ, clears up every trace of recession without making them boxy or sending their higher mids to unbearably harsh territory.
Highs & Treble
The highs of the UiiSii C200 have good brightness and are able to resolve some mild detail. Piercing highs and sibilance are never a problem with them. Highs will probably not offer an audiophile level of SQ but they are fairly achieved. After using an EQ, a lot more of brightness and detail was added making them sound much open and spacious. Sibilant and piercing highs remained absent.
Sound leaking out of the UiiSii C200 is fairly controlled and on most normal situations will not be audible by nearby people. On very silent situations (like in libraries) if a medium to high volume is set they will be heard. For the best earphone in this matter you should check the KZ ATE.
Sound isolation is good and on par with most average earphones, they require the use of higher volume levels to achieve better isolation.
With their ultra light housings and angled nozzles, the UiiSii C200 offer deep and secure fitting while remaining extraordinarily comfortable even on long lasting listening sessions.
Response to Equalization
The response to most custom equalization applied was very good to excellent; bass showed a clear increase in mid-bass punch and sub-bass depth; mids and vocals cleared up noticeably without getting harsh or boxy; highs added a respectable amount of extra brightness and detail with no sibilant or piercing highs issues added.
