About a month ago, I bought a V600 for my wife to upgrade to from her T721. She wanted a camera and a full spectrum phone so it seemed like a logical choice. (I really wanted to see what all the buzz was about anyways). I head a day or two after I got it for her that there was a contest of sorts running where the first 600 people to register their v600 online would win a Motorola HS810 Bluetooth wireless headset. Last Thursday I got this email from Motorola:Dear SEAN MURPHY,Congratulations, you are one of the first 600 people to have purchased the Motorola V600 handset and register your purchase online. As a result, you will receive a free Motorola hands-free Bluetooth® headset.Please note you will be receiving the Motorola hands-free Bluetooth® headset by mail. Please allow 8-10 weeks from this email for delivery of the headset.Whaahooo!!! Friday, there was a box in the mail, one day later. That was the fastest 8-10 weeks I have ever seen.So what is this thing all about?This is an over the ear Bluetooth headset, it will connect wirelessly to any Bluetooth enabled phone, Motorola or not. Here are the specs:- 5cm x 3cm x 2cm when folded - Weighs 20 grams - Increased, talk time of up to 5 hours and standby time of up to 100 hours For $100 you get the headset, a neck strap, a travel charger, carrying case, and manuals. (For free you get the headset and manual and that's it.)The headset has three buttons, two volume buttons, on on the top and bottom, and a multi function button on the outside that acts as a one touch answer hang up and activates voice dialing. With the headset alone, you can answer, call, hang-up and adjust volume, all without taking your phone out of your pocket.Charging:The headset charges using that same style charger that most Motorola phones use (same style as the v600, v60, t721, and so on). Once plugged in it took about an hour to charge fully.Setup:The connection to the phone is a simple one (I was connecting to the v600 in this case) if you read the directions. In my usual way, I messed around for a while before breaking down and getting the book out and once I did I found it to be very easy.The headset has a plug and play aspect to it and the phone can search for near-by devices and then latch on to them. In the case of the headset too, there is a PIN number you have to setup and enter in your phone (I guess so your ear doesn't get hijacked).Once all set up, you have a couple of options for operation, when you flip the mic boom out, the device turns on but your phone can be set to have Bluetooth on or off by default. When on, the act of flipping the boom open automatically connects to the phone and you can talk. This whole process can happen by the 3rd ring if you are quick. Alternatively, if you want to leave Bluetooth off by default (this eliminates any safety concerns of bluejacking, bluesnarfing , or toothing), you need to connect to the headset every time you want to use it which in the case of the V600 requires about 8 clicks and going into the phone setup. This would eliminate the option of doing this to receive a ringing call.Comfort and sound:Wow is this thing light considering what is inside, mic, speaker, batteries, Bluetooth antenna, a pretty blue light, and the guts to make all these things work together and the plastic to hold it together. All that and it rings in at a miniscule 20 grams. That is about 2/3 of an ounce!This thing does sound great to both sides of the conversation. To the wearer of the headset, the calls are clear and near static and noise free with very full sound and bass response compared to most hands free units. To the other side of he call the wearers voice is clear and un muffled. It does not have the sound of a hands free kit at all.Overall:This is a slick unit, it is easy to setup and use, comfortable to wear and sounds great. The only thing holding me back from using one is that my phone is not a Bluetooth device and when I do get BT, I will cringe at the $100 price tag but I will probably break down and get one.
