Long known for their innovative and diverse headsets, the BT200 FreeSpeak is their first Bluetooth headset (www.jabra.com). This is the oddest headset you will ever see. At first, it's difficult to picture how it goes on your ear. You quickly get past this, however, and find that the Jabra goes on with just one hand. This is the most comfortable headset I have ever used, and even did some handyman work around the house for a few hours with it on, and hardly noticed it was there. The ergonomics are excellent, and the sound quality is good, with adjustable volume controls. The FreeSpeak supports the Hands-Free Bluetooth profile, and all the features, like voice dialing, work. The downside is that it takes about five seconds after you turn it on before it connects with the Nokia 3650. This is a problem with the Nokia, though, as other phones are much quicker, like the Motorola V600. After a few minutes of non-use, the 3650 will cut the connection, and you'll have to re-establish it to use the headset. There is no such problem with the V600. The V600 has it's own set of problems, though, like causing a crackling noise in the FreeSpeak. It's the V600, because you don't hear it with other phones. I quickly got used to it, but you'll have to determine how great an issue this is for you. You can leave the FreeSpeak on all day, as the standby time is rated at 96 hours, and typical talk time is 3 hours. Be sure to get a car charger, which is now easily and inexpensively available on ebay. Be aware that the lithium polymer battery is not user replaceable, and you have to return it to the factory after the battery finally dies in about two years. The non-replaceable battery is the only thing I didn't like about the Jabra BT200.
