The audiophone people over at Koss have come out with the Cobalt, a brand new wireless Bluetooth headphone that does pretty much everything you expect of something wireless these days.

The Cobalt lets you pick up a signal from almost any source, from iPods to your cellphone, as the whole package comes with a ton of accessories to help connect it to your gadgets.

In addition to the headphones, you get an audio transmitter, a USB Bluetooth dongle, a charger system and, somewhat ironically, an extension cable. This pretty much covers a whole lot of ground, unless your house is built with inch-thick concrete-and-steel walls, which may just force you to use a regular headphone set-up. At the same time, it can also pick up your phone signal if you want it to, a practice that seems redundant since you probably will need to put the phone close to your face to speak into it, anyway.

Despite those redundancies, it's quite all-purpose. Unfortunately, it costs a ton too. Approximately $180 seems like such a steep price for a set of wireless headphones, even if they do have an 8-hour battery life.

As the largest mobile phone service provider in Brazil and South America (with over 30 million users), VIVO introduces yet another accessory for their VIVOphone -- the new VIVOphone VoiceKey that enables you to connect a cordless phone to VIVOphone and talk for as long as you like for free as you walk around without the hassle of wires and computer cables. With other VoIP products, you just have to put on headphones, grab the mouse, and click on the computer screen to be able to receive VIVOphone and Skype calls. Press the quick dial digits or the phone number digits and you can now dial VIVOphone and Skype contacts from your regular phone!

VIVOphone VoiceKey also allows you to talk to up to nine people at the same time by pressing "#" to switch around or do conference calls with up to five people. It also acts as an adaptor, connecting a regular phone or PBX to a USB port so you can reduce your phone bills as anyone with an extension of the PBX can make calls from his or her extension phone.

Surely, this is a great way to eliminate the fuss with the wires and computer cables that we all hate.
