Older Revision of Lenovo W770 Wireless Headset Review
Lenovo W770 Wireless Headset ReviewThe Lenovo W770 Wireless Headset includes both the headphones and the microphone for a complete communication for your computer. It is wireless, meaning you aren't tethered to your desk while you listen to audio or speak to your correspondent. In this article, we will review this headset in detail. Packaging
Content (Unboxing)The package include the wireless headset, the USB dongle, USB charging cable, user's manual, and warranty information. 
The ear phones has high quality rubber surround and damping cloth. It looks like a headphone with high fidelity for music playback. 
ChargingThere are no electronics truly wireless in the world. And the Lenovo W770 Wireless Headset is no exception. It's wireless in operation. But in order to charge it, you have to use the included USB charging cable (see photo below). 
The charging cable is a proprietary cable that has an standard USB connector on one side and a standard 3.5mm audio connector on the other side. You plug the USB connector into a power source (e.g. your computer), then plug the audio connector into the headset. A LED turns on to indicating that it is charging. The instruction manual claimed that the first time you charge it, you should charge 12 to 24 hours. However, I only charged it for about 2 to 3 hours before the LED turned off. Controls
Using the Wireless Headphones on Windows 7
Putting the Sound Shortcut on Your Desktop
PerformanceOnce the headset works with my Windows 7 set-up, I started testing it for reals. I started playing music videos from YouTube. The music came through loud and clear, but the bass didn't go low enough for most modern music. Looking at the specs, its speakers had a range of 20 Hz - 20 kHz. The wireless function, on the other hand, worked flawlessly. I walked to the other side of the room. The music continued to play without any interruptions. Next, I played a movie with the wireless headset. Much like the YouTube music videos, I didn't get much bass out of the movie, but the added picture dimension distracted my mind from focusing on the music. It will be very useful when I watch a movie in the living room while my kids are asleep.
