Motorola V365
Headset Jack yes, generic phone headsets no?
I've plugged two otherwise satisfactory wired headsets into the headset jack, and they both buzz, a LOT. They work fine with my landline keypads.
Although always buzzing unacceptably (any tone would be unacceptable, but this cannot be ignored), the buzz volume varies as my the phone in my hand moves, as if passing through nodes.
The fidelity, affordability and privacy of wired headsets is Reason One why I chose this model, so I need to resolve this quick.
Go figure, the cheap ones don't buzz. Maybe it's the cord? The clean ones have a two-wire cord, while the headband models' cords look shielded. Buzzing varies and is louder when I hold the phone away from me. Maybe the shielding acts as an antenna?
Or maybe it's different types of mics or earpieces?
