The Avaya SupraElite headset family sets new standards in all-day comfort and reliability for telephone professionals. Enhanced audio quality with a wider receive-side frequency response band, improved headset features such as intelligent exible boom and stylish design, all bring greater audio accuracy and headset exibility to the contact center or office professional. The Avaya AH 450 Headset would also be the envy of most call centre and contact centre agents, whether inbound or outbound dialling. The Avaya AH 450 Corded Headsets are of superior quality and have to be "heard" to be believed. The sound quality is unbelievable as Plantronics have worked closely with Avaya in ensuring that this AH 450 Headset is seamless when paired with the IP Office phone system, along with the Avaya Communication Manager (The IP Office's bigger brother). The range is truly incredible and really gives the user extreme mobility and flexible working to a level not seen before.
