Oneplus Bullets wireless Z2 NackbandThe OnePlus Bullets Wireless Z2 is the successor to the Bullets Wireless Z, but feels like a very familiar experience. The design and fit are nearly the same, save for small changes in the controls. However, the headset has larger 12.4mm drivers, which makes for louder and more bass-focused sound.Battery life and fast charging are excellent on the OnePlus Bullets Wireless Z2, but the headset falls a bit short when it comes to sound quality and features, with some competing options offering better Bluetooth codec support and active noise cancellation. Nonetheless, this is a good pick for anyone who wants a reliable pair of wireless earphones with good battery life.The flagship-level battery life delivers up to 30 hours of non-stop music 2 on a single charge. Stay connected with family and friends for longer with up to 16 hours of talk time3. And with a standby time of 80 hours 3, the Bullets Wireless Z2 is always ready when you are.The buttons have a nice clicky feel and work reliably. However, they are a bit too far apart, so you have to hunt around for them before you find the one you are looking for. Even if your thumb does land on a button, it’s difficult to tell which one it is without sliding it up and down to place it among the trio. It would have been better if all three buttons had fit within the width of the thumb.FeatureWireless NeckbandBluetooth 5.0Up to 10 meters Bluetooth Connection range12.4mm bass driver10-minute charge delivers up to 20 hoursAI Noise CancellationWater and sweat-resistant, the IP55-ratedThe updated skin-friendly silicone materialErgonomically curved design are perfect for all-day wear1 Year Manufacturer Warranty..
