The bracelet acts as a remote speaker and microphone for your smartphone and, as a bonus, displays the time. In practice, the speaker volume is rather low for anywhere where there is much ambient noise, the sound quality is just OK, and, most crucially, the wait for the translation can be a little too long (during which, the shopkeeper, not knowing what you're doing talking to a bracelet and then motioning her to listen to it, will probably mutter something like "Cet homme est un idiot, je ferais mieux de l'humour lui".
The bracelet is easy enough to pair with a smartphone, although setting the time is a clumsy process. You can upload your contact list to the bracelet so the caller's name is displayed when a call is received and, should you step away from your phone, the bracelet will vibrate as soon as you get out of range. You can also connect a headphone and microphone set via the mini jack on the side, so your calls can be private and the bracelet provides about three hours of talk time (not enough for a full day of use) with 60 hours of standby time.
I love the idea of a wristwatch-style device to perform translations, but at $100 and given the translation delay (which you can see in the video below), the limited battery life, and weak sound quality, it's very much a geek toy. It's also not particularly good looking and you'd have to be a really committed geek to wear the style I received for review -- it's the one on the right in the picture above with a black center with pearlescent white sides. I'll give the SpeechTrans Bluetooth Wristband Watch a Gearhead rating of 3 out of 5.
