Double moving coil HIFI metal earphones featuring dual horn design for heavy bass performance, compatible with smartphones and devices using 3.5mm AUX interface, with noise-isolating in-ear construction, available in black or silver colour options.
Double Moving Coil HIFI Metal Earphones with Dual Horn Design and Smart Wire Controls

These metal construction in-ear headphones combine HIFI audio performance with practical functionality for mobile device users. Featuring a double moving coil design paired with dual horn technology, they deliver pronounced bass response alongside clear mid and high frequencies. The 3D surround sound effect creates an immersive listening experience whether enjoying music, podcasts, or multimedia content. With smart wire controls incorporating a built-in microphone, they transition seamlessly between entertainment and communication needs, offering play/pause functions, call answering capabilities, and noise cancelling features in a single portable package.
Technical Specifications and Build Quality

The earphones employ precise engineering specifications to achieve their audio performance while maintaining practical usability across different environments. From the materials selection to the electrical characteristics, each component contributes to the overall functionality described in the product specifications.
Speaker and Audio Performance
At the core of these earphones is a 9.2mm NdFeB (neodymium iron boron) speaker driver that provides the foundation for the audio output. With a rated input power of 3mW and maximum input power of 5mW, it operates efficiently with standard mobile devices without requiring excessive power draw. The 32Ω±15% impedance makes it compatible with most smartphones and portable audio equipment, while the 99±3dB sensitivity at 1KHz 1mW ensures adequate volume levels from typical audio sources. The frequency response extends from 20Hz to 22,000Hz, covering the full range of human hearing with particular emphasis on the lower bass frequencies through the dual horn design.
Construction Materials and Weight
The earphones utilise metal CNC zinc alloy for their housing and structural components, providing a solid feel and durability in daily use. This material choice contributes to the product's 15g weight, creating a balanced distribution that doesn't feel overly heavy during extended wear. The metal construction also provides effective housing for the acoustic components, potentially reducing unwanted resonance that could affect sound quality. The combination of materials results in earphones that feel substantial without being cumbersome, striking a practical balance between build quality and wearing comfort.
Microphone and Control Functions
Integrated into the wire control module is a microphone with -42dB±3dB sensitivity at 1kHz, 3V, designed for clear voice transmission during calls. This specification indicates the microphone's ability to capture speech effectively while potentially minimising background noise. The smart wire controls provide multiple functions including play/pause operations for media playback, answer/off controls for managing phone calls, and noise cancelling features that can enhance call quality. These practical controls eliminate the need to access the connected device directly for common functions, improving convenience during mobile use.
Practical Applications and Compatibility

Designed with versatility in mind, these earphones work across multiple device types and usage scenarios. From mobile communication to entertainment consumption, they address common audio needs for users who require both quality sound reproduction and convenient call functionality in their daily activities.
Device Compatibility and Connection
The earphones feature a standard 3.5mm AUX interface, making them compatible with a wide range of audio equipment including smartphones, computers, MP3 players, MP4 players, and other devices with this common connection type. This universal compatibility ensures they can serve as primary or backup audio solution across different technology platforms without requiring adapters or special cables. The analogue connection provides reliable audio transmission without dependency on specific software or Bluetooth protocols, offering plug-and-play functionality that works immediately upon connection.
Noise Isolation Design Benefits
The in-ear design provides passive noise isolation by creating a seal within the ear canal, which helps reduce ambient environmental sounds during use. This feature proves particularly valuable in noisy environments such as public transport, offices, or urban settings where external noise might otherwise interfere with audio enjoyment or call clarity. By minimising the intrusion of background sounds, listeners can potentially enjoy content at lower volume levels, which may contribute to hearing preservation over extended listening sessions. The design supports focused listening whether for music appreciation, podcast comprehension, or clear conversation during calls.
Temperature and Environmental Operation
With an operational temperature range of -10 to +40 Celsius, these earphones function effectively in most everyday environments and climates. This specification indicates they can withstand typical indoor conditions as well as outdoor use in moderate weather, though they should be protected from extreme temperatures outside this range. The defined operating parameters provide guidance for storage and usage to maintain optimal performance, suggesting they're suitable for daily commuting, office use, home entertainment, and general portable audio applications within these temperature boundaries.
Usage Value and Practical Considerations

These earphones offer specific advantages for users seeking enhanced bass response alongside convenient controls in a durable metal construction. Their design addresses particular audio preferences and practical needs that distinguish them from more basic audio accessories.
Enhanced Bass Performance
The double moving coil design combined with dual horn technology focuses specifically on delivering pronounced bass response, which appeals to listeners who prioritise lower frequency performance in their audio experience. This engineering approach targets music genres where bass elements feature prominently, potentially providing more satisfying reproduction of these frequencies compared to standard single-driver earphones. The heavy bass characteristic represents a deliberate design choice rather than neutral frequency response, catering to users who prefer this particular audio signature in their personal listening.
Convenience Through Integrated Controls
The smart wire controls consolidate multiple functions into an easily accessible module along the cable, reducing dependence on the connected device for basic operations. This integration proves particularly useful during mobile use when retrieving a phone or music player might be inconvenient or unsafe, such as while exercising, commuting, or multitasking. The inclusion of call management functions alongside media controls creates a unified interface for both communication and entertainment needs, potentially streamlining the user experience compared to separate solutions for these different audio applications.
Colour Options and Personal Preference
Available in both black and silver colour variations, these earphones offer aesthetic choice to match personal style preferences or coordinate with other devices. The metal construction in these finishes provides a distinct appearance compared to plastic-bodied alternatives, potentially appealing to users who prefer the visual and tactile qualities of metal electronics. The colour options, while primarily aesthetic, allow for personal expression in what is often a very functional product category, with the silver option potentially showing less visible wear over time compared to darker finishes.
