SR-L300 Limited Earspeakers

Based on the existing SR-L300 Limited, part of Stax’s high-end Lambda series, its has sound elements from the SR-L700 and the ear-pads from the SR-L500. 
Offering high-quality sound with its stainless photo etched electrodes. The Oxygen Free Copper (OFC) ensures seamless and quick transfer of music from your audio player to your headphones while retaining its quality. Last but not the least, the headset is also extremely comfortable with its adjustable headpad and artificial leather earpads.

Welcome to the World of Ear Speakers
The innovative SR-L300 Limited is, like all the others in Stax’s Lambra series, an ultra-high fidelity device due to its electrostatic technology. It produces a sound that would only be comparable to other loudspeakers (& not headphones). Hence, it is only fair that this headset be called an Earspeaker.

Why Electrostatic? 
Electrostatic designed have been pioneered by Stax and they are clearly at the top of the game. The electrostatic headphones operate on a an unconventional level unlike other headphones that feature dynamic and moving coil designs. In most headphones, the drivers are heavier, making it difficult to recreate detail in playback due to mass.

Hi-Class Sound
Keeping in line with its predecessors, the SR-L300 has top notch sound quality. Stainless photo etched electrodes are fixed securely for a clear transparent audio. The headphone gives a balanced sound with delicate highs, soothing mids and a deep bass.

Let Your Music Sound its Best
To keep the quality of music from deteriorating, the Stax SR-L300 uses an Oxygen Free Copper (OFC). This cable uses a wide flat structure to reduce the capacitance between wires and to drive it effectively so that your music always sounds its best.

Extreme Comfort
The SR-L300 is made for comfortable listening. The stepless slider mechanism, lets you adjust the soft headpad for a better fit. This avoids fatigue and enables you to entirely immerse yourself in the music.

Artificial Leather Earpads
Everything about the SR-L300 is made to enhance the sound and your listening experience. This also includes the artificial leather earpads. The flexibility of these earpads provides added comfort while letting you feel the freshness of your music.

SRM-353 BK Headphone Driver
The STAX SRM-353 BK Headphone Amp is special development crafted from carefully selected high-quality parts resulting in wide frequency response, natural tonal quality and extended dynamic range at high frequencies! Carefully selected high-quality parts of an audio grade further improve the tone quality, and re-examination of circuit details realized much wider frequency response. XLR input terminal provided to connect to the balanced output of audio equipment taking advantage of its superior performance.

• Original low-noise dual FET at first stage and all-stage direct coupling Class-A DC amplifier configuration with no coupling capacitor produces natural tone quality with loads of detail.
• Improved emitter follower at output stage has enabled wide-range reproduction resulting in both extended dynamic range at high frequencies and improved tonal quality.
• In additional to RCA input terminal, XLR balanced input terminal is provided to connect to a wide range of audio equipment.
• Custom-made 2-axis 4-gang volume controller is employed.
• Extravagant non-magnetic aluminum alloy chassis of STAX tradition is adopted.
• Components with little aging characteristics are selected carefully in consideration of tonal quality and performance.
