JPL 501 Monaural, Noise Cancelling Office Headset
The JPL 501 single-ear headset equipped with acoustic shock protection and quick disconnect functions is the ideal office headset for regular phone users seeking all-day comfort.
Built-in acoustic shock protection (ASP)
The ASP feature is designed to protect you from exposure to loud, sustained, and piercing tones during your voice calls. It works by detecting a sharp tone at the ASP module input, causing the audio path in the direction of that sound to be muted in order to protect the listener. So, instead of hearing loud, piercing tones, you hear a gentle alert tone for as long as the disturbance persists.
Comfortable quick disconnect 
The quick disconnect lead allows you swiftly disconnect your JPL 501 headset and move away from your workstation without necessarily removing the headset, which effectively puts that caller on hold.
Option for left or right ear wearing
This single-ear headset can be worn on either your right or left ear, and its fully adjustable sure-fit headband offers you adequate flexibility for comfortable wearing.
Why should you buy this monaural office headset?
With its noise-cancelling feature and in-line quick disconnect, users can be assured of flawless conversations without disruptions by unexpected noise or other forms of interruption. Additionally, the JPL 501 has an adjustable headband and swivel mic boom that makes it a very flexible model, and well suited for office or home use.
