Notionally they are a headset also but they don't have a microphone boom on them but rather it's integrated into one of the ear pads. They are noise cancelling, and very very good at it.</div><div class="gmail_extra"><br></div><div class="gmail_extra">More broadly I've spent a fair bit of time looking at Bluetooth audio because it might be helpful in the context of using mobile phones as fieldwork tools. Without blasting you with technicals, here's some observations:</div><div class="gmail_extra"><br></div><div class="gmail_extra">The microphone aspect of the Bluetooth headset profile allows for low-latency audio but the quality is diabolical. It's designed for phones. </div><div class="gmail_extra"><br></div><div class="gmail_extra">The high quality Bluetooth audio profile (A2DP) allows for quite good quality audio. It's unidirectional, usually it appears as a headphone profile on a paired device. It's designed for streaming music. If you take a call, that happens via the headset profile.</div><div class="gmail_extra"><br></div><div class="gmail_extra">The high quality audio is high latency, sometimes really high latency. If equipment supports the proprietary AptX codec then the quality can be very good and the latency moderately low. It's a bit of a pain making sure this happens. Forget anything Apple related for a start.</div><div class="gmail_extra"><div><br></div><div>Bottom line, if you want to do work with it, e.g. record what people are saying, I think Bluetooth is inappropriate.</div><div><br></div><div>If you want a wireless headset that plays music well, does noise cancelling for travelling, and also allows you to make phone calls then the Plantronics Backbeat Pros are excellent. You can also jack in an audio cable for a wired connection for playback but not recording.</div><div><br></div>-- <br><div class="gmail_signature">Regards,<br><br>Mat Bettinson<br><br></div>
