I primarily use my Cardo S640 to do teleconferences during my commute. I spend most of my meeting time on mute, so it was important to me to have an easy to operate mute button. The mute is set by holding down the volume button for a couple seconds. This is a little awkward. (I would prefer to have a separate button.) But while it’s on mute, there is a mute indicator light, which is wonderful.
I usually attach it to my seatbelt, which works well. But I find that it doesn’t work too well to wear it if you have a buttonless shirt. It clips okay, but because it is vertical, you can’t clip the earbud in the microphone piece.
It’s nice and compact — when I’m not using it, I just stuff it in my jeans pocket.

After trying and being disappointed by the many of the Bluetooth devices out there, I found this Cardo device listed for those who wear glasses. Many devices have a clip that secures the device on the ear and it doesn’t fit well when you have your eyeglasses already occupying the area behind your ears (feels like wearing two pairs at the same time).
The in ear type devices tend to be difficult to secure so they don’t fall out, or very uncomfortable to wear for any extended period of time. My ears tend to be sensitive so they don’t like having anything crammed in there for even short periods of time before becoming unbearable.
The main advantages I have found on the S-640 are:
1. The device clips on your shirt when not in use. I usually clip it on my polo shirts between the buttons, clip the microphone into the holder and tuck the cord away inside the shirt.
2. The battery life is excellent. My Blackberry is usually dead way before the Cardo is, and I get between 1 and 2 days worth of use between charging. Since the device is relatively inexpensive (less than $30 on Amazon with shipping), I have bought two and simply take one off the charger in the morning and plug the other one in, so I have a fully charged device every time before leaving my office each day.
3. Since the microphone is below your face instead of being located on the ear, I have found that the voice quality is much better than other devices tested (some friends have this so I have experienced this device from both sides). Most people can’t tell if I am using the handset or the Cardo.
4. The device appears to be rather sturdy since I have dropped mine several times on my driveway and it has taken quite a bit of abuse without breaking.
5. The sound quality is excellent. The #1 complaint about Bluetooth devices is that they are not loud enough. On my Blackberry 8330, I usually have it on level 7 or 8 in my car (out of 10) and it is plenty loud.
6. The range of the headset is impressive. I can leave my BB on my desk in my office on the second floor of my house and can roam the entire second floor and large part of the first floor before static sets in. I would say you can use this trouble free 30 feet away without any issues.
7. It charges very quickly, when empty it is usually fully charged in about 90 minutes or so. A car charger is not available from Cardo, but I have found them on Ebay and various sites for about $5.
The disadvantages I feel are minor but they are:
1. It would have been nice to charge this with a mini USB (or micro USB or any standard connector), which is the most common complaint on this device.
2. There is no noise canceling so it picks up wind noise very easily. When I drive, I have to make the A/C vents blow away from my face. Outside it will pick up wind noise because there is no windscreen on the device.
I have found that the solution to this is to flip the device around and have the microphone face my shirt. It appears to kill any wind noise without muffling my voice. People I talk to don’t seem to notice the difference except the wind noise is gone.
3. Because it is on the front of my shirt, it occasionally gets snagged if I brush too close to something. Not a major issue, but something watch out for because it can get left behind when snagged.
The earpiece is very comfortable and I can wear it in my rather sensitive ears for several hours without any discomfort. It sits very securely and I don’t have any problems with it falling out.
Since this device appears discontinued and is getting difficult to find, I’ll probably stock up on a few spares since this is the only BT device I have found usable.

I’ve tried a number of various brands Bluetooth; each has some kind of problem, the fit, the weight, sound quality or battery life. This one, in comparison, is the best.
First, the earpiece fits well and very light, the sound quality is good on both sides of the conversation, and battery life is not bad at all. Unlike the common one-piece head sets, which require one to hang the entire device from their ear, this ear bud is much lighter, because the clip-on piece has the microphone, the rechargeable battery, and everything else that make it work. In addition, you don’t have to leave it in your ear all the time, the clip piece has a built in ringer, so you can wear the ear bud only when you answer a call.
Pairing was very fast easy, same goes for turning on/off, or changing the volume.
Two minor cons: the power button on the ear bud needs some use-to, and the charger is not the universal mini USB, it has an unusual extra small rounded plug, which means you have to bring it with you if you want to use the headset, plus a car charger in addition to your phone’s chargers. One star off for these cons.
Over all, this is a good product and better than any one-piece Bluetooth I’ve ever tried.
