    One of the sales guys at work has one to go with his new Ericson phone.

    Looks very cool, very small solid over the ear "ear piece", with a small jaw line boom mic.

    Here in the UK these guys have several bluetooth earpieces.

    some more info here
    Another UK store

    And lots of nice links to bluetooth handsfreeThis might be more useful if your in the US

    Wow, those are cool looking.

    Here in Cali they are really pushing the hands free sets for driving safety. I have tried to use one of those ear bud things, but noticed that it was more dangerous for me to pull the thing out and untangle the wire than it was for me to just make the two minute call in the usual way.

    This would (probably) fix that problem. But it looks like something I would totally lose in my car. But I guess that's my own problem.


    Now a question. If the sound is digitized, wouldn't it also be encrypted for saftey? I mean, your cell phone is supposed to be 'encrypted', so why would you just retransmit it over an insecure setting? SO, if it's encrypted how the hell are you supposed to "interface it to the computer" as Skraggy_uk suggested? Were you speaking of using a Bluetooth WLan card? or some other method?

    The only way I could see it is if you hacked one of the transciever modules, and had it output to your mic line or line in on your sound card.

    On the plus side if you did hack the transiever module, you could have the computer output directly to the headset via an unused output line (such as suround sound, or an extra sound card). So you could recieve voice commands and whatnot from the computer, without interupting your music, or your passengers.

    Sorry if this is incoherent, I'm still hung over!

    Not to solid on the details of bluetooth, but it is fairly short range, same room kind of distance.

    I think with the headsets, once they are locked onto a phone etc, they stay locked, so you shouldn't end up answering someone elses cell phone.

    I know what you mean about normal handsfree, I'm not always wearing a shirt with a pocket in, so I have nowhere safe to put the phone.

    I usually ignore it when I'm driving. If it's important they will ring back, if they don't, and they don't display call ID, then they obviously didn't think it was too urgent for me to ring back straight away.

    I imagine that the Computer use for those would be on suitable PCs with Bluetooth on the motheboard, and a driver to use it (like USB/firewire gear), manufacturers would supply that driver to suit an OS api MAC OSX/Win32 API/Linux kernel module, it would just be like yet another serial/Parallel/USB/IRDA bus port.


    I imagine that some form of encryption like WEP would be in use as an option (maybe even built into the negotiation firmware on gear like headsets).

    Although believe it or not even digital stuff like GSM isn't totally secure, do you think intelligence agencies would actually allow something that they couldn't decode if needed?

    They might not be able to trace you to closer than the nearest Cell (in a big city that might be as narrow as three apartment buildings), but they will be able to hear what you say if they need to.

    As I said believe I'm not to sure on the finer points of bluetooth, but I know a couple of the guys in the Office have bluetooth phones, and when they go into meetings together, the phones notice each other, and even identiy the the device by the Phonebook entry if it is present.

    Think of it as omni direction longer range IRDA, all compatable devices talk to each other.

    And like USB, if a blue tooth device is detected by a PDA or Laptop/PC then it will identify itself just like your webcam/scanner/gamepad does, and when the OS knows what it is, it will load the device, so your bluetooth will then become another input/output speaker/mic channel

    Oh trust me, I'm all to aware of the insecurities involved with Bluetooth. Check out this website, I have a dozen more on WarChalking if you'd like.

    I think you're right, the BlueTooth equipment would be aware of eachother, that's what the whole hardware protocol is about. But would you actually be able to recieve and send streaming audio, without some sort of additional audio codecs?

    You can hack the WEC's easy enough, you only need a couple hundred MB of transmision interception to be able to decipher it. And since it uses the same key without changing, once you figure it you'll always have it.

    The encryption that's gonna be the pain is in the audio codecs. Maybe you could get lucky and they are using Ogg Vorbis (it is open source), or maybe they paid to use MP3 (highly doubt that). Or maybe they just made one up, and you'll have to decipher it. I believe that's where your problems will be.

    I'm not a great programmer, and I know even less about audio so I may be WAY off base on this. If any body knows better, please PIPE UP!!!

    I myself would like to know about something like that.

    but I wonder if the shortrange of bluetooth is part the way there?
    if someone tried to listen in, or decode what you are doing, then surely in a lot of cases they would be close enough to see what they are doing?

    And if you move away and they follow, you got them.

    I suppose. But what if they were in a car just behind you? Or in an apartment net door? They could be standing three feet from you, or immediately below you and you wouldn't even know it! Or they could just be using a high gain 2.4GHz antenna. Maybe even have an amplifier. I used to be into Ham Radio, so I know this equipment is VERY easily purchased by the common citizen. Or, as always, you could just build it.

    I could easily triple the distance with a good antenna, and maybe double that with an amp. But it all depends on local noise and the quality of the transmission.

    There was a story here in the US that a person had set up a Bluetooth system in their apartment, and didn't think to turn on the encryption. One of thier neighbors connected to the internet via this connection without even trying, and started distributing pirated movies. The FBI traced it back to the poor fool who owned the DSL line, but after trashing his apartment they found no evidence. It took them several days to discover it was the guys neighbor!

    Doing security tests at work, we've had guys get signals down the street. And if anybody wanted to hack it, and they had the time to do it, they could.

    ->But this is off the topic. I'd just like one of those to be CLEANLY interfaced to my computer. Preferably through its WLan. It's already there, and set up. Why not use it? Does anybody here know what it's using for codecs? I really doubt that it's transmitting straight digital audio in full duplex, I don't think it has the throughput.

    I'm coming into this thread a little late, but what do you mean with this statement? Why can't you use a headset in the car? I have an earpiece and mic for my phone and a week or so ago, I saw a guy driving his Porsche with a full wrap-around-the-cocconut headset. If I were to do voice, I wouldn't use anything BUT a headset, but maybe I misunderstood you.

    Try voodoo voice 2 - its much better. Has loads of commands and they are customizable. I ran it for a while on my laptop with just the laptop micropohone. Its cool! But, its a hefty 80mb odd download from memory!

    I think a lot of problems using voice control software in a car could be ironed out by simply mounting a small button on the dash or steering wheel to turn the mic on and off. Maybe you could just take a regular mic and wire a momentary switch to one of the ground or signal wires?

    Andrew, have you got a web address for Voodoo Voice? Google gets nothing of any use.
