Portable Headphone Amplifier with EQ Adjustment and a Built-In Battery will achieve a true sound via your headphones.
This small and compact designed headphone amplifier is known as the “SAP-7” is an ideal accessory for anyone that likes to listen to music via their headphones. When traveling around or commuting to work, most people like to listen to music, either via their mobile phone, mp3 player or some other sort of media device. However, not all the time the music is clear, may have echo, or sound distorted and that is why this lightweight headphone amplifier comes into action as it simply connects to your media device’s headphone socket and then you plug your headphones into the amplifier and all your music that you are listening to gets played through the amplifier, which will clear the noise and improve the sound. Basically the purpose of the “SAP-7” is to replace the standard, lower in quality amplifying circuit that is in most portable music players in order to improve the overall sound quality. Also the “SAP-7” amplifier is to provide enough 'juice' to audiophile's headphones, which usually are much more demanding than what most music players can handle.
