> losing data or experiencing slow data on a phone put the headset into a near-unusable state
This makes me think that the voice processing is done server-side. I wouldn't be at all surprised by this; that's how Siri does it, and I would be amazed if they managed to fit good enough voice recognition into even a phone, let alone this tiny thing.
The headset doesn't appear to be as big as a phone: so I'm wondering whether the headset talks to a phone that then talks to Google, or whether the headset really does the lot.
The device gets data through Wi-Fi on its own, or it can tether via Bluetooth to an Android device or iPhone and use its 3G or 4G data while out and about.
Is there some way to activate this option? Sometimes it seems my voice input is bottlenecked by the connection when I'm driving in a low-coverage area.
