Understanding Direct Connect Cables vs. Amplifiers:

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: (Poly 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 each call may be required depending on your phone
