Product Description
 
This 50mm headphone speaker driver is a premium choice for DIY headphone builders and audio equipment manufacturers, engineered to deliver studio-grade sound quality with exceptional consistency.
 
Powered by a N52-grade strong magnet (15.5mm×3mm, 3mm center hole), it generates a robust magnetic field that enables fast, accurate diaphragm movement. The 3-layer composite black diaphragm with copper ring minimizes distortion and maintains a flat frequency response from 20Hz to 2kHz, where vocals and acoustic instruments sound natural and lifelike.
 
The frequency curve extends smoothly up to 20kHz, with a gentle lift in the 2kHz–4kHz range to enhance speech clarity, followed by a natural roll-off that preserves high-frequency airiness without harshness. With 24Ω impedance, 119.73dB sensitivity, and power handling of 20mW rated / 25mW max, it balances efficiency with dynamic range for an immersive listening experience.
 
At only 18g, this driver is lightweight and easy to install, while its ultra-consistent performance ensures every unit delivers the same precise sound.
