See our Polycom IP Phone Headsets page for latest the compatible headsets

If you have Polycom Soundpoint IP phones like the IP300, IP301, IP335, IP430, IP450, IP500, IP501, IP550, IP560, IP600, IP601, IP650, IP670 (Rev E or later) with a dedicated headset jack, it has been determined by Plantronics that it will ONLY work properly with the Plantronics H-Series “SupraPlus” line (HW251, HW251N, HW261, HW261N) or “TriStar” line (H81, H81N) headsets along with a Plantronics Polaris Cable (part# 27190-01). The other H-Series models will not work properly and it causes a terrible "buzzing" sound from the headset. Do not use other Plantronics models not listed here.

For GN Netcom/Jabra headsets, use any GN Netcom direct connect headsets (includes the GN1200 smart cable) Also see our GN Netcom - Polycom Compatbility Guide

If you're looking for wireless for your Polycom IP phones, we recommend Plantronics CS55,or the Plantronics CS70N, however, these wireless headsets must be plugged in through your phone's receiver port, not your headset port. If you're using the Plantronics HL10 lifter remote answering option with your IP phone, you will need the Plantronics Lifter Accessory for Polycom IP Phones.

If you have the model SoundPoint IP 320/321, 330/331, 335, 430, 550, 560, 650, 670, you can use the Plantronics APP-5 or Plantronics APP-50 hook switch cable with any of the Plantronics wireless headsets without the use of the HL10 lifter.

• APP-5 is designed for the Plantronics CS50, CS55 , CS70, CS70N , CS351, CS351N, CS361, CS361N , 510S,510SL
• APP-50 is designed for Plantronics WO100, WO200, WO300,WO350, W710, W720, W730, W740, W745. Also the new CS540,CS510, CS520, CS530

*Note: IP 320/321, IP 330/331 - requires Plantronics 2.5mm to RJ9 adapter (part# 78333-01). When using 78333-01 bypass the EHS cable audio connection. Connect 78333-01 directly between CS base and phone headset connector
