Headset specifications
Your Treo uses a 2.5mm, 3-pin headset connector. Your Treo 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.
Your Treo 650 is also compatible with headsets enabled with Bluetooth 1.1
wireless technology. This includes most of the headsets with Bluetooth wireless
technology currently available, as many of these headsets support both Bluetooth 1.1
and 1.2 wireless technology. Check the specifications for your headset to confirm
compatibility. Please note, however, that you cannot use a headset with Bluetooth
wireless technology to listen to MP3 files.
In addition to the headset
that came with your Treo,
you can use other third-
party headsets.
To hear stereo through the
jack (such as music), you
should use a stereo
adapter or other accessory.
