EAR FSM-01 is a high-fidelity amplification of the input music to a portable headphone amplifier signals.
This product is properly connected to your music player (such as CD/MD/MP3/MP4 or mobile phone, etc ...), in addition to greater overall output power, easy to drive from 16ohm to 300ohm impedance, earplugs or a variety of headphones, the music can also bring you a wonderful new experience.
Built-in 3 (LO / MI / HI) gain adjustment, to facilitate users to select the most appropriate output mode.
Carefully selected parts and good parts of the circuit design, LEAR FSM-01 is absolutely stable and reliable performance.
Taking into account the needs of mobile users, we 3.5MM in FSM-01's headphone jack for hands-free wire to add support for headphones. So when you are using a speakerphone or a headset with remote control operation, and its function can be used normally.
Pursuit of more power or stability for customers in power, LEAR FSM-01 also has a separate external power supply jack, can at any time from the DC 3V-5.5V corresponds to the external power supply. You can simply use the computer's USB-based products for electricity or charge, you can also design their own high-quality more than DC5.5V external power supply, built-in 3.7V lithium-based products break through the limitations, to drive the high impedance earbuds or headphones.
