12-Unit Circle Iron Earphone Adjustable Tone Monitor In-ear Changeable Wire Wired Headphones with Microphone Option Black Creative Design Back Winding Fit
Black Wired In-ear Earphones with Adjustable Tone and Changeable Wire

These wired in-ear earphones are supplied as a set with a headphone cable, replacement core, replacement tool, instruction manual, box, and one pair of headphones. The design uses a circle iron style with a back winding wearing method, and the plug type is through-hole. The earphones are available in black, with choices between regular and adjustable tone versions, and between models with or without a microphone. This makes them relevant for buyers who want a wired in-ear monitor format with the option to change the cable and adjust tone where supported by the selected version. Because the source text does not provide measurements or detailed technical specifications, the description stays close to the stated features and included items.
Features and Construction

The main construction points are the circle iron design, the back winding wearing method, and the through-hole plug. The set also includes a replacement core and replacement tool, which relate to the changeable wire feature. These details are useful for anyone comparing wired in-ear monitors that allow cable replacement rather than a fixed cable.
Material and Build
The source text does not state specific materials. The term circle iron appears in the product title, but no further material breakdown is provided. What is confirmed is the wired connection, the through-hole plug type, and the inclusion of a replacement core and tool. The black colour applies across the listed options. For buyers who need exact material data, this information is not available in the source text, so no further claims are made.
Size and Practical Fit
No dimensions or weight are given in the source text. The wearing method is back winding, which describes how the earphones are intended to sit in the ear. The in-ear monitor format is suited to listening while moving or monitoring audio, but the exact fit depends on the ear tips and the selected version. Because no size measurements are supplied, this description does not invent any fit numbers.
Uses and Placement

These earphones are wired, so they need a compatible device with a through-hole plug connection. The microphone option, where selected, adds a microphone to the earphone set. The adjustable tone option, where selected, provides tone adjustment. The changeable wire design supports cable replacement using the included core and tool.
Event or Professional Use
The in-ear monitor format and back winding wearing method are relevant for monitoring situations where a wired connection is preferred. The adjustable tone version may suit users who want to change the tone output, while the microphone version may suit those who need to speak as well as listen. No professional certifications or performance ratings are stated, so the description remains limited to the listed features.
Everyday Home Use
For everyday listening at home or on the move, the wired connection avoids the need for charging. The black design is paired with the circle iron look, and the set includes a box for storage. The cable, replacement core, and replacement tool are included, which supports the changeable wire feature. No battery life or wireless range is relevant because these are wired headphones.
Benefits and Buying Value

The practical value comes from the wired in-ear design, the option to choose microphone or no microphone, regular or adjustable tone, and the included replacement parts. The changeable wire feature means the cable can be replaced using the supplied core and tool. The set also includes an instruction manual and box, so the main accessories are provided together.
Reuse and Low Maintenance
Because the wire is changeable and a replacement core and tool are included, the earphones can be maintained by replacing the cable rather than the whole set, where the user follows the manual. No specific cleaning or care instructions are provided in the source text, so only basic storage in the included box is suggested. The black finish is consistent across the listed colour options.
Why Choose This Product
This product is relevant for buyers who want wired in-ear monitor earphones with a circle iron design, a back winding fit, and a through-hole plug. The choice of microphone and adjustable tone versions allows the buyer to select the configuration that matches their needs. The package includes the headphone pair, cable, replacement core, replacement tool, manual, and box. No further specifications are available in the source text, so the buying decision rests on these stated features and the selected option.
