Noise Cancellation
Hi Nichole,
You said:
[quote]I'm unfortunately not too clear on the exact technology involved, but I think what happens is that the microphone on the headset picks up on the noise, finds the pattern, and then "reflects" back the noise so that it is canceled out.[/quote]
Years ago, I worked for Bob Cohen, who invented the ClearCom headset (you see 'em used for communication in extreme noise environments -- helicopter cockpits, sporting event remote broadcasts, rock concerts, etc.).
Bob's solution used paired directional mics; one pointing at the user's mouth, the other 180 degrees away, coupled to a simple summing device that blocked all signal picked up by both mics, transmitting a "mix minus" signal that permitted ONLY the unique sound picked up by the voice mic.
I would assume the basic concept remains the same on any good quality Bluetooth set.
Hi
Nicole,
I have a t-mobile dash. I want to back up my entire phone is there any software which will do that preferableover usb or bluetooth. also i have two bluetooth profiles I want to be able to seamlessly switch between my gps and my headset is it possible
clip-style BT
Are there a lot of BT headset which has the BT electronics away from the ear (like the Cardo S-640)?
Headset while using a Motorcycle Helmet
Is there any Bluetooth headsets that you can recommend that are to be used when wearing a motorcycle helmet? I just ordered a Garmin Zumo 550 GPS which has Bluetooth capabilities (for audible directions, listening to MP3's & talking on cell phones). I can't see how one of those over-the-ear things could be comfortable with a full faced helmet.
Bluetooth for Iphone
I currently have an iphone and I was wondering if there are any bluetooth stereo headphones that are available for it? If not then do you see any that are going to be available in the future that will just plug into the speaker jack of the phone and transmit to bluetooth stereo headphones?
A2DP for iphone coming? icombi in the meantime
Nicole,
I notice you said that Macs don't currently support A2DP, but its coming with "leopard". The current iphone doesn't support it either. Have you any idea if and when it will?
In the meantime, I've heard that icombi makes an adaptor that turns the iphone into an A2DP unit. Does this work for music with the iphone, and will it also switch properly for telephone use?
Thank you.

Article problem
Hello,
My RSS just pointed me to an article on Crave about all the new motorola models. That article contains a link to a slideshow of the new phones, but the link isn't working -- it points to a page titled: "null".

stereo headphones, not headsets
I'm looking for a good set of BT headphones, with the highest quality available for music. I don't want an "in ear" but rather a full over the head or around the head type. It would be great if they had noise reduction as well. What would you recommend, and do you like the new Sony BT headphones.
best bluetooth headset for driving?
I will be using my headset while driving. I have read reviews at CNET and see that the jawbone gets highest marks.
Does the noise canceling really work?
Would you receommend this over the planatronics you recommend in your "DEPENDS!" answer?
Motorola H700 Bluetooth Headset
Nicole,
I was recently looking into buying the Motorola H700 Bluetooth Headset. I like the foldable mike and it falls within my price range. I saw your review on it and and I am still skeptical. Is it comfortable when you put it on? Can you fold the mic when it is on your ear? How is the quality of the calls when using it? I want a bluetooth that I can user for the long term? Would you recomend me buying this for my first bluetooth?
Thanks!

Cardo s2 great
just to say i love BT technology and I'm sold on the cardo s2 which works well with my samsung blk jack, stereo sound, AD2S ? i believe it's called, I can ff/rev/pause and hold all on the right ear peice. It looks cool nd it's very comfy for me, does'nt look nerdy, the wires just get in the way, and it's at a very reasonable price, I got mine for less than $70.00 and i love it.
Sony Cyber-shot DSC T200
How do you rate this new product and how does it compare to the T100 model?
Lotus Notes
I have Lotus Notes email at work and want to get a new cell phone to be able to get my email and internet while out of the office. I called Lotus Support and they indicated I had to have an "Enterprise Server" and true wireless synchronizing, etc.
Is there a simpler software I can install on the cell phone to be able to get to my Notes email? Also what type phone is compatible with Lotus Notes.
Best headsets for hard of hearing
I am young but wear hearing aids (slight hearing loss). The problem I have had with Bluetooth headsets in the past is that even at their loudest volume I still can't hear the caller well if I am not wearing the hearing aids and they don't work well when wearing them. 2 questions: 1) are there any Bluetooth headsets which you can volume up pretty high and 2) are there any headsets that you can use when wearing hearing aids?
Stereo/Phonecall Combo Bluetooth?
Is there a bluetooth headset that combines ability to listen through music on your "music-capable phone", as well as takes calls? I'd prefer one that is just like a normal one-ear bluetooth, but also transmits music. I'm not requiring GREAT AUDIO SOUND, just the ability to casually hear some tunes as I'm doing whatever. I tried the Motorola S9 headphones, but they were too big to carry around and too difficult to get on in time for a call, and my hair got in the way, plus weren't too comfortable.
For use indoors
I'm not too concerned about noise reduction as I want a stereo bluetooth headset for indoor use: answering business Skype calls on my MacBook Pro laptop and chatting with friends via video (Skype or iChat) while cooking. And maybe watching DVDs while my better half is asleep. I will NOT be using it with a cell phone, only a laptop.
Is there anything I should be looking for (other than comfort and sound quality) for using with a laptop? And which headsets do you recommend that do not involve sticking something in your ear canal?
Plantronics 665a
I have the Plantronics 665a with "AudioIQ", I'd love it if it had more of a deep in-ear attachment instead of the soft-gel...I always find myself holding my ear/pushing it deeper so I can hear better when I am in a not-quiet environment. Are there universal ear attachments that one can buy, or do you know of a bluetooth that has great sound, no ear hook, and a deep-ear attachment? : )
