Headset specifications
Your Treo™ 650 smartphone uses a 2.5mm, 3-pin headset connector and works with
headsets that are designed for this type of connector. When in doubt, ask the third-
party headset manufacturer if the product is compatible with Treo smartphones. If you
hear a headset buzz or poor microphone performance, your headset may be
incompatible with Treo smartphones.
Your Treo smartphone is also compatible with headsets and car kits enabled with
®
Bluetooth 1.1 wireless technology. This includes most of the headsets and car kits
with Bluetooth wireless technology currently available, as many of these headsets and
car kits support both Bluetooth 1.1 and 1.2 wireless technology. Check the
specifications for your headset or car kit to confirm compatibility. Please note,
however, that you cannot use a headset with Bluetooth wireless technology to listen
to MP3 files.
