Problem with Samsung x427 and non-OEM headsets

Archived from groups: alt.cellular,alt.cellular.cingular (More info?)

So far I've tried Jabra and Plantronics, on 2 different x427 sets. In
both cases, the headset seemed to work fine at first. However, then
when you call a number (and the headset starts tranmitting) I get
considerable noise on the headset. It varies by twisting the
connector (again on both x427 phones). Noise is the same as using my
Cingular phones close to a landline phone. That is, if the cell phone
is real close to the landline phone, I hear a similar noise on the
landline phone. Keep trying headsets or return the phones? TIA.
