Despite the name, the Bullets Wireless Z are clearly not fully wireless given the buds are attached to wires. The neckbud design allows for a wireless connection to your device, with the headphones hanging around your neck when not in use. Previous Bullets Wireless have had magnetic backs to the buds that auto-play and -pause the audio, a great feature.
We liked both the first and second Bullets Wireless, though the second-gen upped the price from £69/$69 to £99/$99. We hope the Wireless Z stick to the same price to make them worth recommending.
