1. The very stable working performance.
As you may know, for most of BT products on the market, the signal of the earbuds are not very steady and would be easily cut off. And the working distance normally cannot reach to 10 meters.

The main complain for current similar products on the market is the short working time. Most of products cannot even working for 2 hours. But for RK2, there is custom battery of 40 mAh for each earphone.Music playing time could up to 2.5 hours.And there is charging box that can instore 450mAh battery, you can charge RK2 wherever you are.  

3. Competitive price.
