The SR-003MK2 is a portable in-ear earphone with a 5-pin PRO connector that can be used when connected to a headphone amplifier with a 5-pin PRO output connector. The redesigned SR-003 ear canal type structure allows you to enjoy excellent electrostatic sound quality without covering your ears. The SR-003MK2 is connected to devices or with a STAX adapter equipped with a 5-pin PRO bias output.
The Stax SR-L300 also used rigid, fixed electrodes treated with stencil photo etching. Thus, the rich deep bass response, subtle treble and smoothing midrange were implemented in a balanced manner. The Stax SR-L300 headband is equipped with a sliding mechanism for height adjustment.
For added convenience of use and comfort when listening to music, the Stax SR-L500MKII model has an easily removable cable, as well as a U-shaped holder of sound-emitting capsules made of aluminum. The replaceable, easy-to-remove cable was designed to meet current trends in high-end headphone design, making it possible to quickly replace the high-definition cable to enhance their usability.
The ear pads of the model are filled with memory-effect material and trimmed with soft sheepskin. The developers claimed a frequency range from 7 Hz to 41,000 Hz with an impedance of 145 kOhm and a sound pressure of 101 dB / 100 V RMS. The weight of the headphones is quite small — only 234 grams.
The Stax SR-009 headphones have a new sound element. Its membrane uses an ultra-thin film made of the latest high-molecular polymer, also known as multilayer structural plastic. It is much stronger and thinner than ordinary structural plastic. The use of the best materials has made it possible to achieve excellent frequency response over the entire frequency range, along with a huge dynamic range.
