When you re creating your own home videos, usually the last thing you think about is the audio. Because of this neglect, your sound quality is left to the devices of the on-camera mic, ending up sounding like a cross between a transistor radio and fingernails on a chalkboard. Now Sony Japan comes to the rescue with its ECM-HW1 Bluetooth wireless mono microphone whose receiver is specially made to attach to the shoe adapter atop certain Sony HandiCams. It's nice and small, too, with the microphone weighing slightly less than an ounce and measuring 1.3 x .9 x 2.5 inches, and the clip-on receiver weighing in at about 2 ounces and measuring 1.9 x 2.1 x 2.8 inches. According to the company, the system works on the following Sony digital camcorders: the DCR-DVD505, DCR-DVD405, DCR-SR100, HDR-HC1, DCR-HC96, DCR-DVD203, DCR-HC41 and DCR-HC90. So now you can use this mic up to 33 feet away from the camera (your mileage will certainly vary), and not have to mess with pesky wires, either. It's unknown whether this device will work with other camcorders, but knowing Sony, it's probably completely proprietary. It will be available in Japan in February for 21,000 ($165).
