## Long description

Replacement foam ear cushions designed for Poly Blackwire C310 and C320 headsets. This set contains two black foam cushions that fit over the headset ear cups to restore original padding and hygiene for office or remote-work headsets. Lightweight and breathable foam provides basic comfort for daily calls and extended wear when a simple, low-profile ear pad is required.
Advantages
These foam ear cushions offer an easy, cost-effective way to refresh worn or damaged padding without replacing the entire headset. Their soft foam construction reduces pressure on the ears and maintains a low-profile fit that preserves microphone placement and headset balance. The black finish masks everyday wear and matches the original headset aesthetics.
Suitable for
Replacing worn ear pads on Poly Blackwire C310 and C320 headsets
Office environments with frequent use of headsets for calls
Home or remote-work setups where hygiene and comfort need restoration
Lightweight padding needs for users who prefer minimal ear coverage
Key specifications
Material: soft open-cell foam for breathability
Color: black
Set contents: two ear cushions (left and right)
Compatibility: designed to fit Poly Blackwire C310 and C320 over-ear cups
Profile: low-profile, lightweight padding suitable for extended wear
How to use
To replace the ear cushions, remove the old foam pads from the headset ear cups by gently pulling them away from the rim. Align a replacement cushion with the ear cup and stretch it into place, ensuring the edges sit securely around the cup rim. Repeat the process for the second ear cup. Check that cushions are seated evenly and that microphone positioning and headset fit are not affected before use.
Usage recommendations
Clean the headset ear cups with a dry or slightly damp cloth before installing new cushions. Replace foam cushions periodically to maintain hygiene, especially in shared environments. Avoid exposing foam pads to oils, solvents, or high heat to prolong their service life.
