Recently, OnePlus released a set of in-ear earphones made of aluminum called the “OnePlus Silver Bullet Earphones.” It went on sale on September 26 at 10:30 AM for 99 RMB (16.11 USD).
Although these earphones only cost 99 RMB, it has a lot of technological selling points such as its use of NPEI diaphragm which is lighter, and slimmer, and a faster vibration rate letting the earphones emit a clearer and more natural sound quality.
The Silver Bullet Earphones have a wire that has an in-line module with three buttons. The texture and elasticity of the wire are pretty good. The module lets the user play or pause music, as well as increase or decrease the volume. It is also compatible with mainstream Android phones. It was twisted more than 30,000 times and pulled for 60 seconds for OnePiece’s severe endurance tests which it passed.
There is also a special mixer App for the OnePlus One regarding the Silver Bullet Earphones which users can use to adjust the earphones’ sound frequency.
