Japanese company AD-TECH launched the world’s smallest and lightest blue tooth headset. It is claimed to provide 3 hours of talk time and 100 hours of stand by. The design was made with the concern of people’s ergonomic issue of having a little to much weight on their ears. No status on availability in the United States, but available in Japan for 8,980 yens.

“It is truly miniature with dimensions of 0.9” x 0.86” x 1.2” and weight of only 0.01 oz (5 grams).”
