Neckband form factor offers great call quality and longer lasting battery life. This form factor is supported by Apple with their recent released Beats Flex. OnePlus backed this form factor long time ago with their first Bullets Wireless, they also released the premium sounding Wireless 2 and entry-level Wireless Z, take a look at our comparison to see what they differ technically and sonically.
Head to head comparison between Oneplus Bullets Wireless Z Vs. Bullets Wireless 2 – two neckband Bluetooth earbuds which one is better?
Neckband is not just making the entire earbuds construction more durable, it allows audio engineers to build more hardware on the neckband, sparing earbuds housing for more drivers. The first thing I found out when inspect the specs of two sets is the driver configuration – Wireless 2′ DD + 2 BA makes their sounds significantly better than Wireless Z, though Bluetooth chipset also plays an important role – while Wireless 2 supports AptX HD the Wireless Z doesn’t.
Neckband form factor Bluetooth earbuds are still favored by commuters and office workers.

Which One Is Better?
Oneplus tried to popularize Bullets Wireless Z with advanced feature like quick charging and superior call quality, but the sound quality is not that consumer oriented – like with massive bass or balanced sound, rather their sound is less pronounced in all departments, and given the TWS earbuds you can find a pair with better sound quality. Bullets Wireless 2 just tops the Wireless Z for sound – yes it gets sophisticated driver configuration and more solid Bluetooth connection.
