These LG's use Harmon and Kardon sound technology, so in essence, it's the cheapest way to get a pair of Harman/Kardon Bluetooth headphones.
Brad's Deals Editor Michael,
The LG Tone Infinim Bluetooth Stereo Headset (HBS-910) drops from $149.99 to $69.99 at TechRabbit. Even better, the shipping is free. This is the best price we could find for a pair by $20. The Tone Infinim have received high marks from Amazon Reviewers and feature Harman Kardon tuned retractable earbuds, active noise cancelling dual-microphones, Bluetooth 4.1 with a 40ft range, and a 10-hour battery life. There is no sales tax (except NJ).
