Headset Compatibility with Phones Using Power Adapters
Headsets with impedance imbalances along their acoustic path create electrical interference that can
cause some users to hear a low-frequency hum or buzz sound. This noise can be present in the near-end
headset speaker and/or could be transmitted to be heard at the far-end receiving headset. This is most
noticeable when using a 2-pin non-grounded power adapter like the one supplied with the legacy
SoundPoint IP phones. Phones using Power over Ethernet (PoE) as a power source are not usually
affected by imbalanced headsets because they receive a DC voltage from an isolated PoE source. The
sound can be more obvious in environments near large transformers or other sources of electrical
interference.
You can mitigate the interference by using a 3-pin grounded power supply with your phone. A 3-pin 24V
power supply is qualified for use with SoundPoint IP phone models 321/331, 335, and 450, while a 3-pin
48V power supply is qualified for use with phone models 560, 670, and VVX 1500 phones. Both power
supply adapters are available from your Polycom reseller. Note that SKU numbers vary by geographical
location.
Your headset manufacturer may offer Improved Common Mode Rejection Ratio (CMMR) type headsets to
reduce interference. You may also wish to try other headset models in combination with different phones
to troubleshoot and isolate the issue. For further information, contact your headset manufacturer directly.
