The Sound Associates SA650HX is a wireless monaural infrared headset designed for professional applications. While other wireless headphones suffer from poor reception and fidelity, Sound Associates' sophisticated receiving circuitry with dual receiving diodes is extremely sensitive and new high-performance micro speakers give the headsets remarkable audio reproduction.
