Headset Specifications
Your Treo 650 uses a 2.5 mm, 3-pin headset connector. In addition to the headset
that came with your Treo, you can use other third-party headsets that are
designed for this type of connector. When in doubt, ask the third-party headset
manufacturer if their product is compatible with Treo smart devices. If you hear a
headset buzz or poor microphone performance, your headset may be
incompatible with Treo 650.
Your Treo 650 is also compatible with headsets enabled with Bluetooth 1.1
wireless technology. This includes most of the headsets currently available with
Bluetooth® wireless technology, 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.
If you want to listen to music through the headset jack in stereo, use a stereo
adapter or other accessory.

current compatibility information.
Tip:
If you’re using a headset enabled with Bluetooth wireless technology
and you want to return to the handset during a call, select
Cancel
on
the Active Call screen.
Note:
The headset designed for Treo
™
180, 270 and 300 is not compatible with
Treo 650. Standard headsets sold with other Sprint phones are
compatible with Treo 650.
