The LG HBM-770 looks a lot like its cousin, the LG HBM-755, and it has similar features. However, the HBM-770 Bluetooth headset comes with echo cancellation and noise suppression, which makes it a little better than the other LG headsets. It's also a bit pricier at $79.99.
The HBM-770 looks a bit like the skinnier, sleeker, and more sophisticated version of the HBM-755. It has the same smooth electric blue reflective coating, but is decidedly blockier around the edges. Measuring 1.7 inch long by 0.75 inch wide by 0.4 inch deep, the HBM-770 is also just as lightweight and compact. The top portion of the front surface can be pressed down to act as the multifunction key, and there's also a blue LED that flashes when the HBM-770 is powered on. The volume rocker sits on the left spine, and there's a dedicated power button on the top. All keys are easy enough to press, even when the headset is worn on the ear. The charger jack is on the right.
