OnePlus 2, which succeeds the OnePlus One, will be released in the Q2 or Q3 of 2015. This was confirmed in the OnePlus One Reddit AMA post.

A recent report by iDigitalTimes said that the OnePlus 2 may possibly come in a relatively smaller size and be powered by Google's latest operating system, the Android L.

Another report by Know Your Mobile quoted OnePlus One officials saying that currently they are working on the headset of OnePlus 2, as the users complained about the bigger size of OnePlus One's headset.

They said, "We've seen a lot of people asking for a smaller device, and want to let everyone know that we hear you. We're thinking about it."

Although, the OnePlus One was launched to rave reviews, it was met with much frustration from some users. A couple of early technical issues - such as yellowish displays and undelivered software features - have also contributed to the shaky launch. However, many of those issues have since been cleared up.

In addition, the Know Your Mobile report said that, having confirmed the OnePlus 2 release date, the company has also revealed that they have already developed a new "high spec in-ear headphones," which is available at affordable price.

The new headphones have been named Silver Bullet Earphones and are available for just $15 from September 29 in all the 16 launch countries.

In a blog post, OnePlus stated, "We have meticulously engineered the Silver Bullet to deliver powerful and immersive sound while ensuring a compact yet durable feel. The brushed aluminum casing perfectly complements the rugged texture of the One's Sandstone Black cover. Best of all, now you are in control of your music, camera, and voice calls without ever having to reach for your One."
