Adtec AD-HSM10 claims to be smallest

Bluetooth headsets are dime a dozen, and they tend to be within a standard size range but the Adtec AD-HSM10 wants to be different, coming in a form factor that claims to be the smallest in the world. It weighs a mere 5 grams, measuring 0.9” x 0.86” x 1.2”. Now that’s really tiny – hopefully its small size does not fail it when it comes to performance. Size matter, but it isn’t everything. You can choose from silver or titanium colors. According to Adtec, this Bluetooth headset has 3 and 100 hours of talk and standby time respectively. It will be released later next month for less than $80. How much smaller do you think Bluetooth headsets should get?
