After Saturday's virtual Mac User Group meeting via Zoom, I observed the Plantronics headset I'd had since 2012 had lost virtually all of the foam padding on the earpieces, making it incredibly uncomfortable to use.
I looked into getting replacement cushions but that headset is obsolete now. Others of the same brand looked like they might fit but there was no guarantee.
Any I did but were either priced too high or packaged with too many inside. EG: a pair of cushions for $23 or 10 pairs for $18. Plus the delivery time meant I'd have to endure the hard plastic earpieces for two to three weeks.
Bit the bullet, bought a Logitech H390 headset on Sunday, it arrived today.
