OnePlus is accompanying its new phone launch today by also releasing its first pair of wireless headphones, called the Bullets Wireless. Yes, they support USB-C fast charging, are Google Assistant-integrated, weather-resistant, and use the AptX codec for better Bluetooth audio quality, but they’re not the “truly wireless” in-ear wireless buds you might’ve been expecting.

Regardless, they have specs that might make them great wireless headphones. On paper, OnePlus claims you can get five hours of usage from ten minutes of charging, or top it off for eight hours of battery.
