Product Description

This item is really more of a Bluetooth headset clip than a Bluetooth headset. This is meant for those of you that like the convenience of a Bluetooth headset but don't like wearing it all the time. You clip the headset to your shirt, and then you can either wear the attached wired earbud in your ear, or simply tuck it into the clip. The headset will also buzz or vibrate when there's an incoming call. The S-640 has a rated talk time of 6 hours and a standby time of about 6 days.

I have been using this for some time now. It has been working great. Its nice and small and it lasts for a long time. i usually charge it every other day. I use this with my HTC Kaiser Windows Mobile phone without any problems. The pairing process was nice and smooth. The volume changing is a little annoying as its only one button that goes from the highest to the lowest but other than that its perfect. The voice quality is excellent.

This review is from: Cardo Systems S640 Bluetooth Headset (Wireless Phone Accessory)

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.

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.

It is my first bluetooth headset and I am very happy with it. Setting up was very easy and smooth.

I also paired it with skype running on my bluetooth enabled laptop and worked great.

Now I can receive skype calls anywhere in my home. I bought it to use it with my MOTO RAZR but since most of the calls I make/receive through skype, I thought of giving it a try and it worked like a cakewalk :).

No connection loss issue till now.

Highly recommended.
