Beyerdynamic A1 Headphone Amplifier

The A1 headphone amplifier challenges the boundaries of personal audio reproduction. Streamlined by beyerdynamic's research, the A1 headphone amplifier manages frequencies beyond the range of human hearing to render a broad range of uncompressed frequencies flawlessly. The A1's micro-processor-controlled relay allows for noiseless switching between audio signals and prevents clicking when powering the A1. The end result of using the A1 is a listening experience that redefines expectation.
