FC12 In-ear Headset with Microphone and 3.5mm Wired Plug

The FC12 in-ear headset is a wired earphone with a 3.5mm plug, a built-in microphone, and silicone earplugs. It is available in black FC12, black FC12A, and silver white FC12A colour options. The frequency range is 20-20000, and the stated sensitivity is 48. This product is produced through independent research and development, and it is supplied in paper card blister packaging. It is intended for listening to music and for voice communication when connected to a compatible device. Because the source text provides only limited technical detail, this description stays close to the stated specifications and does not add unsupported performance claims. The information below covers the features and construction, uses and placement, and benefits and buying value of the FC12 in-ear headset.
Features and Construction

The FC12 is built around a wired in-ear format with a 3.5mm plug and silicone earplugs. These details are the main source-supported construction points. The headset also includes a microphone, so it can handle both listening and voice input. The available colour options are black FC12, black FC12A, and silver white FC12A.
Material and Build
The earplugs are made from silicone, which is the stated material for the ear tips. Silicone is a common choice for in-ear headphones because it can form a soft contact point at the ear. The product uses a 3.5mm plug, so it is a wired headphone rather than a wireless model. The frequency range is listed as 20-20000, covering the standard audible range for music and speech. Sensitivity is given as 48. The headset is produced through independent research and development.
Size and Practical Fit
The only size-related measurement provided is the 3.5mm plug diameter, which indicates the connection type. This is a standard size for many audio devices that use a 3.5mm socket. The in-ear design uses silicone earplugs, which sit inside the ear. No other dimensions, cable length, or weight figures are given in the source text, so those details cannot be confirmed here. The product is supplied in paper card blister packaging, which is a compact retail format.
Uses and Placement

The FC12 is suited to situations where a wired 3.5mm connection is available and hands-free voice input is useful. That includes listening to music, following audio on a computer, or taking calls through a compatible device. The microphone supports voice communication, while the in-ear silicone earplugs provide the listening interface. The colour choices allow for a black or silver white finish depending on the variant selected.
Event or Professional Use
For event or professional settings, the FC12 can be used where a wired in-ear headset with a microphone is required. The 3.5mm plug connects to compatible audio equipment with a matching socket. The microphone allows for spoken input, which is useful for communication tasks. The silicone earplugs are the stated ear tip material. Because the source does not provide noise isolation figures, waterproof ratings, or specialist certifications, no such claims are made. The black or silver white colour options may help match existing equipment.
Everyday Home Use
At home, the FC12 can be used for music listening, online calls, or other audio activities through a device with a 3.5mm socket. The wired connection means no pairing or charging is required, based on the stated wired headphone type. The built-in microphone supports voice chat when the connected device allows it. The silicone earplugs are designed to sit in the ear, and the frequency range of 20-20000 covers common audio content. The product is available in three stated colour variants: black FC12, black FC12A, and silver white FC12A.
Benefits and Buying Value

The main buying value of the FC12 lies in its straightforward wired design, its 3.5mm plug, and its built-in microphone. It uses silicone earplugs and comes in a choice of black or silver white colour options. The frequency range and sensitivity are stated, but no further performance data is provided. This makes it a practical option for users who want a wired in-ear headset for general audio and voice use.
Reuse and Low Maintenance
As a wired headset, the FC12 does not rely on a battery for operation, based on the source text. The silicone earplugs are the stated ear tip material, and the product is supplied in paper card blister packaging. No specific cleaning or maintenance instructions are given in the source, so only basic low-risk care should be assumed. Keeping the 3.5mm plug clean and storing the earphones in the packaging when not in use are reasonable general practices. No lifespan or durability claims are made because the source does not provide them.
Why Choose This Product
Choose the FC12 if you need a wired in-ear headset with a 3.5mm plug, a microphone, and silicone earplugs. It is available in black FC12, black FC12A, and silver white FC12A, so there is a colour option to suit different preferences. The frequency range is listed as 20-20000, and sensitivity is 48. The product is produced through independent research and development and supplied in paper card blister packaging. No price, pack count beyond one earphone, or competitor comparisons are stated in the source, so those points are not claimed here.
