This OPA2107 Class A Portable Headphone Amplifier from PMD Way offers a significant improvement in performance over plugging straight into your portable audio device.
Particularly with larger enclosed type headphones which are not as efficient as their earbud counterparts. This amplifier will give you a substantial gain in signal-to-noise, reduce distortion, increase dynamic range and overall volume, not to mention a great deal more listening plaeasure.
Your sound quality is the number one concern, and the amplifier is built with quality components such as shielded audio sockets from Foxconn, quality Omron relays, Elna capacitors - and a super-strong alloy metal enclosure.
This headphone amplifier arrives fully-assembled, and is powered by an internal rechargeable Lithium Polymer battery - which can be recharged via the DC power socket.
Your headphones plug into the amplifier as normal, however you will need a 3.5mm stereo jack cable to connect the amplifier to your music source.
