Buy.com this week has lowered the price of the LG HBM-520 Bluetooth headset (model no. HBM-520) to $29.99, which is 16% off its list price of $35.99 and the lowest cost we have seen for this particular Bluetooth headset by about $28. FREE shipping is included and sales tax applies for residents of New York and California.

Buy.com also has an upgraded Bluetooth headset that’s a little more expensive than the featured product, the Plantronics Voyager 510 on for $42.75 with FREE shipping included. The Voyager is available at a 57% off discount and has a four out of five star customer rating for quality. While the HMB-520 is the more affordable buy, it isn’t quite as well liked by customers and is basically a “you get what you pay for" device. If you’re looking for more positioning support to ensure your headset doesn’t fall off, then check out the Motorola S9-HD headset with D650 iPod adapter and carrying case priced at $82.32 with FREE shipping. Or simply get yourself an iPod adapter by purchasing the Sony Bluetooth Wireless Transmitter, which can also be found at Amazon.com and is available for only $54.40.

The LG HBM-520 Bluetooth Headset offers users up to 7 hours of talk time or 200 hours of standby time per a single charge, and has a range of 33-feet. It supports Bluetooth v2.0 technology and comes with answer, reject, end-call, and last number redial call functions.
