Cardo S640 Bluetooth Headset                           

(Review) - Cardo's S640 Bluetooth headset promises to be a trend setter that's going to change the way we use wireless headsets. Although we've all enjoyed the wireless capability of Bluetooth headsets, the idea to wear them around the ears has always been wishy-washy. It tends to get awkward wearing a headset with bright blinking LED lights for hours and occupy your ear to avoid missing a call. With the S640, that's a thing of the past.

Logitech Premium Headset Review

The S640 is your average Bluetooth headset with internal buzz on/off, mute, volume control, voice dialing and a myriad of expected features. There's nothing new from that perspective, but as is the case with Cardo and its product line, they are unique in one way or another. So, in terms of design, that's where the S640 shines and shines brightly. The unit sports a black glossy exterior that adds a professional touch to the headset. Although it's fingerprint prone, it's relatively manageable due to the headset's size. In addition, it also features a clip-on design rather than an over-the-ear design that we are so used to. Not only does that prevent your ears from getting tired, but it's also pleasant and hassle-free to work with. While the main portion of the headset clips on to your shirt, the earbud is just long enough to reach your ears. And once you are done talking, you can slide it back and somewhat hide the wire as well. Of course, the visual LED alerts are present as well to make working with the device a pleasure. Needless to say, it's a great design that we expect other companies to adopt shortly.

From an audio quality standpoint, it couldn't have sounded better. The S640 was an absolute pleasure to use, as the call quality was static-free and crystal clear from both ends. According to Cardo, the battery life is rated at 6 hours of talk time and up to 150 hours of standby time. In our tests, we managed to talk for 6:17 hours before the headset needed a recharge. While we don't have many concerns, the only thing that is a bit annoying is the volume control. You can't simply push a couple of buttons to up/down the volume. Instead, you have to tap the headset which will slowly adjust the volume levels. That's just cumbersome. However, we don't expect a lot of you to work with the volume settings too much, so maybe it won't be such a concerning factor after all.

All in all, the Cardo S640 ($59.99) is a must have product for mobile users who are looking for an excellent and unobtrusive way of keeping in touch with family and friends.
