Bluetooth earpieces are a dime a dozen, but few are as sleek as the BULLET Bluetooth 4.1 by Schatzii. The earpiece/charging capsule is the world’s smallest Bluetooth Earbud, weighing a mere 3.5g. The ultra lightweight design is only a small part of its appeal, as this also delivers crisp, clear sound. If you’ve been on the hunt for a Bluetooth piece, you may very well find it in the Bullet Bluetooth 4.1.
