Designed for listeners seeking a detailed sound profile with an emphasis on low-end response, the dual horn architecture works to produce pronounced bass. The 9.2mm NdFeB speaker delivers a wide frequency range from 20Hz to 22KHz, capturing both deep notes and high-frequency details. Integrated smart wire controls offer direct command over music playback and phone calls via a built-in microphone, making them a practical choice for everyday mobile use. Their noise-isolating in-ear design helps minimise external distractions, while the standard 3.5mm AUX jack ensures broad compatibility with smartphones, computers, and portable media players.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black metal in-ear headphones with smart wire control and microphone for mobile phones\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/904\/2025-10-02\/original-image\/355035404205.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe headphones are built with a focus on durable materials and audio engineering to provide a consistent listening experience. Key elements include the metal housing and a speaker system designed for both power and range.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe primary construction uses metal CNC zinc alloy, contributing to the product's overall 15g weight and offering a solid, metallic feel. This material choice provides the structural foundation for the internal audio components, including the double moving coil assembly and the dual horn design. The build focuses on housing the 9.2mm NdFeB speaker, which has a rated input power of 3mW and a maximum input power of 5mW. The technical design aims to support the HIFI sound reproduction goal and the targeted heavy bass output.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eWeighing 15g, the headphones are designed for portability and extended wear. The piston-style in-ear design is intended to create a noise-isolating seal within the ear canal, which can help reduce ambient noise during use. This fit is central to achieving the claimed audio performance, particularly for bass response. The provided specifications include an impedance of 32Ω±15% and a sensitivity of 99±3dB at 1KHz 1mW, figures which relate to how the headphones interact with various audio sources. The operating temperature range is specified from -10°C to +40°C.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black metal in-ear headphones with smart wire control and microphone for mobile phones\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/904\/2025-10-02\/original-image\/452021416340.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThese headphones are engineered for personal audio listening across multiple devices and scenarios, from mobile communication to dedicated music playback.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eThe combination of HIFI sound, heavy bass focus, and noise isolation makes them suitable for immersive music listening, gaming, or video consumption where audio detail is valued. The built-in microphone and call control functions allow for clear voice communication during phone or video calls, supporting remote work or communication needs. Their broad frequency response may cater to users who require audio monitoring across a wide spectrum.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor daily activities, the smart wire control offers convenient management of music playback—play, pause, and track switching—without needing to access the connected device.
