According to rumors, OnePlus is said to be working on Nord TWS earbuds to go with its line of mid-range smartphones.
Renders based on live images of the final prototyping stage units were leaked giving us an idea of the general look of the alleged TWS.

Based on the renders, it appears to have a physical button on the earbuds in gold. Additionally, they look to have a shorter but drastically wider stem.

The Nord TWS Earbuds are expected to be cheaper than the OnePlus TWS counterparts just like the smartphones. The alleged TWS earbuds are also expected to arrive later this year.
Not much else is known about them though as of writing this.
