The Logitech is marketing their newly launched bluetooth earphones LBT-PCHP02 as the world's smallest earphones as of now. Weighted just around 1/3 ounces, the LBT-PCHP02 are light enough to qualify for the tag of world's smallest as well as lightest.

The LBT-PCHP02 bluetooth earphones have been rated as Bluetooth 2.1 + EDR and will be shortly available for shipping in US by October. Battery life for the LBT-PCHP02 is around 4 hours which could be a limiting factor for music buffs but the size of the earphones is surely a reason behind the 4 hour battery backup.
The bluetooth earphones are available in four colors silver, pink, gold and black. The package includes different sizes of ear tips for different kind of shapes. The price tag for this 1.3 inches long and 0.23 inches thick LBT-PCHP02 bluetooth earphones is approximately USD$54 in Japan now. We hope that Logitech would improve the battery life of the earphones in the future.
