Metal HIFI Earphones with Double Moving Coil Design and CNC Zinc Alloy Construction for Enhanced Bass Response

These metal HIFI earphones combine practical audio functionality with durable construction materials. The double moving coil and double horn design aims to deliver enhanced bass response alongside 3D surround sound effects, while the noise-isolating in-ear approach helps reduce ambient noise during use. With smart wire control featuring a built-in microphone, users can manage calls and music playback directly from the cable, making these earphones suitable for smartphone, computer, and portable media player applications where hands-free operation is beneficial.

Features and Construction

The earphones utilise specific design elements and materials to achieve their audio performance characteristics. From the double horn configuration to the metal housing construction, each component contributes to the overall functionality while maintaining portability for everyday use across different devices and environments.

Material and Build

Constructed from CNC zinc alloy metal, these earphones feature a durable housing that weighs 15g. This metal construction provides the physical structure for the internal components while contributing to the product's overall aesthetic and feel. The materials selection focuses on creating a solid foundation for the audio components housed within, with the CNC machining process allowing for precise manufacturing of the earphone casing.

Size and Practical Fit

With piston in-ear design, these earphones aim to provide a secure fit that contributes to noise isolation by reducing ambient sound intrusion. The physical dimensions accommodate the 9.2mm NdFeB speaker within each earpiece, while the overall weight of 15g helps maintain comfort during extended listening sessions. The design considers both audio performance and wearability for portable use across different activities and environments.

Uses and Placement

These earphones serve multiple audio applications from casual listening to communication needs. Their compatibility with various devices and inclusion of microphone functionality expands their utility beyond simple music playback to include practical communication features for modern digital lifestyles.

Event or Professional Use

For situations requiring clear audio monitoring or communication, the earphones' 99±3dB sensitivity and 32Ω impedance provide adequate audio output levels. The built-in microphone with -42dB±3dB sensitivity enables voice capture for calls or recordings, while the operating temperature range of -10°C to +40°C supports use in various environmental conditions. These specifications make them suitable for professional scenarios where reliable audio performance is needed.

Everyday Home Use

In home environments, these earphones connect to smartphones, computers, MP3 and MP4 players through the standard 3.5mm AUX interface. The smart wire control allows convenient management of music playback with play/pause and song switching functions, while the call answering capability supports communication without removing the earphones. The noise-isolating design helps create a more focused listening experience by reducing ambient household sounds during use.

Benefits and Buying Value

The combination of audio specifications and practical features positions these earphones as a functional audio accessory. Their design addresses both sound reproduction and user interaction needs through integrated controls and microphone functionality, providing multiple uses from a single portable audio device.

Reuse and Low Maintenance

With metal construction and specified operating parameters, these earphones are designed for repeated use across their supported temperature range. The 3mW rated input power and 5mW maximum input power specifications indicate appropriate power handling for extended operation, while the impedance and sensitivity figures suggest compatibility with common audio sources without requiring specialised amplification for normal listening levels.

Why Choose This Product

These earphones offer specific audio characteristics through their double moving coil and double horn design aimed at enhancing bass response. The metal construction provides durability while the integrated controls add functionality for device interaction. With frequency response spanning 20-22K Hz and clear power specifications, users can understand the technical capabilities before purchase, making informed decisions based on documented performance parameters rather than vague claims.
