Poly HIS Adapter Cable with Quick Disconnect

Poly HIS Adapter Cable with Quick Disconnect

When using any H-series headset, a Direct Connect Cable or amplifier is required to plug in between your headset and phone.  Using a Direct Connect Cable will save you money versus an amplifier, but an amplifier will provide optimum sound quality and volume controls.

Direct Connect Cable:

• Less expensive
• Easy to install into headset port
• Takes up virtually no desk space
• Limited to use with compatible phones only (Your future phone may not be compatible and require an amplifier)

Amplifier:(Plantronics M22)

• Compatible with most phones
• Battery or AC powered to provide optimal sound quality
• Speaker volume adjustment
• Microphone volume adjustment (Key point that Direct Connect Cable doesn’t have)
• Lifting handset with each call may be required, depending on your phone
