Bluetooth stereo headphones: We tested a number of stereo Bluetooth headphones; all paired quickly with the iPad and routed most audio—for example, audio from the iPod and Video apps, and sound from games—through the headphones. However, audio from the Skype app wasn’t routed through the headphones, and for those Bluetooth headphones that included a microphone, that microphone did not work with Skype or audio-recording apps. In addition, as with the iPhone, if your Bluetooth headphones provide on-headphone controls, the only playback control you get via Bluetooth headphones is volume level and a play/pause toggle. Here’s hoping iPhone OS 4.0—or, even better, an update to iPhone OS 3—finally brings us AVRCP, the Bluetooth profile that allows full playback control via Bluetooth headphones and speakers.
Bluetooth mono headsets: We tested the iPad with several Bluetooth mono headsets and were unable to pair with any of them—none even showed up in the iPad’s Bluetooth screen when discoverable. Former PCWorld Editor-in-Chief Harry McCracken had similar experiences. However, we’ve had at least one report from someone who did get a mono Jabra Bluetooth headset working with an iPad. We’re conducting further testing on this one. Update: A Macworld reader informs us that Jabra's recent mono headsets are actually A2DP-capable, so the aforementioned Jabra headset was likely paired as an A2DP device. Which would seem to confirm our suspicions that the iPad's software doesn't support the necessary Bluetooth profile(s) for standard mono headsets.
