Mobile phone headset with moving iron driver technology, featuring 20-40000Hz frequency response, 20Ω impedance, and 101dB sensitivity, available with straight 3.5mm plug in black colour with choice of mic or no-mic styles
Mobile phone headset with moving iron driver technology and 20-40000Hz frequency response range

This in-ear mobile phone headset utilises moving iron driver technology to deliver audio reproduction directly from your smartphone or mobile device. With a frequency response that spans from 20Hz to 40000Hz, the earphones cover the full range of human hearing and extend beyond into ultrasonic frequencies. The combination of 20Ω impedance and 101dB sensitivity makes these earphones efficiently driven by standard mobile phone audio outputs without requiring additional amplification equipment. Available in black colour with choice between microphone-equipped and non-microphone styles, this wired headset connects via a standard 3.5mm straight plug for compatibility with traditional audio jacks and adaptors.
Features and Construction

The headset's core specifications centre around its moving iron driver technology and practical design elements suited for mobile phone use. With a 1.2m cable length providing reasonable reach during typical smartphone handling, and options for both call-enabled and audio-only configurations, the construction addresses different user requirements for communication and media consumption.
Material and Build
The headphone cable utilises TPE (thermoplastic elastomer) material, which offers flexibility and durability for daily mobile use where cables frequently experience bending and handling. Earplugs feature skin-friendly silicone sleeves designed for comfortable in-ear placement, with the material chosen to minimise irritation during extended wear periods. The straight 3.5mm plug provides reliable connection to standard audio ports without the added bulk of angled connectors.
Size and Practical Fit
With 4mm diameter speakers housed within the earphone casing, the drivers are compact enough for comfortable in-ear placement while delivering adequate sound output for personal listening. The 1.2m cable length allows practical movement when using the headset with a smartphone held in hand or placed on a nearby surface. The choice between 'With Wheat' (microphone) and 'No Wheat' (no microphone) styles accommodates different usage scenarios, whether prioritising call functionality or purely music listening.
Uses and Placement

Designed specifically as a mobile phone headset, this product addresses both communication and entertainment needs for smartphone users. The technical specifications and physical design elements support practical application in everyday mobile scenarios, from commuting to home use.
Event or Professional Use
For professional scenarios requiring clear voice transmission, the 'With Wheat' style provides microphone functionality suitable for phone calls, video conferencing, or voice command applications. The 101dB sensitivity ensures adequate volume for listening in various environments, while the 1% distortion rate specification indicates minimal signal alteration during audio reproduction. The moving iron driver technology may offer advantages for detailed audio monitoring in content creation or precise communication settings.
Everyday Home Use
For general mobile entertainment, the headset's 20-40000Hz frequency response covers musical content across genres, from deep bass to extended highs. The skin-friendly silicone sleeves promote comfort during extended listening sessions, while the TPE cable material withstands typical home use handling. The straight 3.5mm plug connects directly to smartphones, tablets, laptops, or audio adaptors without requiring specialised connectors or wireless pairing procedures.
Benefits and Buying Value

The headset's value proposition centres on its specific technical specifications and practical design choices that address mobile audio needs. Without inventing comparative claims or unsupported performance benefits, the product offers measurable specifications that inform purchase decisions.
Reuse and Low Maintenance
The TPE cable material's flexibility and durability support repeated use without cable damage from typical coiling and storage. Silicone ear sleeves can be cleaned with mild solutions if needed, maintaining hygienic conditions for personal audio equipment. The standard 3.5mm connector ensures compatibility across multiple devices and generations of mobile technology, extending the product's usable lifespan as devices evolve.
Why Choose This Product
This headset provides moving iron driver technology within specifications suited to smartphone power outputs, with a choice between communication-focused and media-focused configurations. The 20-40000Hz frequency response, 20Ω impedance, and 101dB sensitivity represent measurable audio performance parameters rather than subjective quality claims. For users seeking a wired connection option with specific technical characteristics and style choices, this product offers defined specifications to inform selection.
