In-Ear Headphones with Metal Subwoofer: 20-2000Hz Frequency Response and Universal 3.5mm Connectivity

These wired in-ear headphones combine a 10mm metal subwoofer driver with a 1.2m TPE cable and 3.5mm in-line plug, delivering 20-2000Hz frequency response across gaming, music, and communication applications. The 110dB sensitivity ensures clear audio reproduction from mobile devices, computers, and MP3 players without requiring external amplification, while the built-in microphone provides hands-free calling capability. With 32Ω impedance and 0.02% distortion rate, these headphones maintain audio fidelity across various media types.

Audio Performance and Construction Features

The headphones incorporate specific technical specifications that determine their audio quality and durability, from driver components to cable materials.

Metal Subwoofer Driver Design

A 10mm diameter driver housed in metal subwoofer construction enhances bass response while maintaining structural integrity. The metal housing provides acoustic benefits by reducing resonance compared to plastic alternatives, contributing to clearer audio reproduction. This design choice supports the 20-2000Hz frequency range specified for the headphones.

Technical Audio Specifications

The 20-2000Hz frequency response captures both low-frequency bass notes at 20Hz and high-frequency treble tones at 2000Hz. With 110dB sensitivity, the headphones produce audible sound at lower power inputs, while the 32Ω impedance ensures compatibility with standard audio outputs. The 0.02% distortion rate indicates minimal signal alteration during audio transmission.

Cable and Connection Quality

A 1.2m TPE (thermoplastic elastomer) cable provides flexibility while resisting tangles during daily use. The 3.5mm in-line plug connects directly to universal audio sources without requiring adapters. This construction maintains signal integrity across the cable length while withstanding regular bending and coiling.

Practical Applications and Usage Scenarios

These headphones serve multiple purposes from professional communication to personal entertainment, with specific features supporting each use case.

Gaming and Communication Use

The built-in microphone enables clear voice transmission during gaming sessions or phone calls, while the 20-2000Hz frequency range captures game audio details and voice communications. The 1.2m cable length provides sufficient reach for desktop gaming setups or mobile device use without restricting movement.

Music and Media Consumption

For music listening, the metal subwoofer enhances bass response while the silicone ear tips create acoustic seal that improves noise isolation. The 0.02% distortion rate maintains audio fidelity across various music genres, from bass-heavy electronic tracks to vocal-focused acoustic recordings. The secure in-ear fit prevents slippage during physical activity.

Mobile and Computer Versatility

User Benefits and Value Considerations Specific technical features translate to practical benefits for users across different applications and usage patterns.

Long-Term Value Proposition

User Experience SatisfactionPurchase Decision Factors</h3 The combination of 20-2000Hz frequency response, metal subwoofer construction, and universal connectivity addresses multiple audio needs with a single product. The 1.2m cable length accommodates various usage scenarios while the built-in microphone adds communication functionality beyond basic audio playback. These specifications provide measurable performance across gaming, music, and communication applications.
