In comparison to titanium and aluminum, beryllium diaphragms excel in their top octave decay characteristics and shapes, establishing them as top-tier high-impedance drivers. These drivers are available in two versions: 30 ohms for mobile phones and 600 ohms for amplifier devices. Please select the version that best suits your requirements and indulge in the pristine, natural sound that "ELFINEAR" drivers offer.

Packaged as a pair of two 600ohm speaker drivers, it's essential to test them with a multimeter before soldering. Remember to look for the colored spot, which is the positive pole, and solder for less than 3 seconds to avoid burning out the voice coil or circuit board easily.

These speaker drivers are non-mass production items specially designed for DIY lovers and audiophiles, made by ELFINEAR's skilled engineers. Upgrade your earphones with ELFINEAR's 600ohm DIY earphone speaker driver replacement, and experience the purest sound quality.
