Thanks to Amazon Prime, I received my new Bluetooth earphones the next day after placing the order. I will be replacing the Plantronics BackBeat Go 2 which is having an issue as discussed in this post.
It came in a nice pouch with lots of other spare ear tips and a charging micro USB cable. The default eartips worked fine for me so I didn't change them.
At first I paired it with my iPhone 6 which is my day to day phone at the moment. I could easily pair it with the iPhone. It shows the battery level of the earbuds when it is connected just like the Backbeats. The quality is very good too, much better than the Backbeats. The quality of the Backbeats were quite poor. I didn't feel this initially, but even compared to the Apple EarPods, they were very clumsy. Remember though that I'm not an audiophile and this is a subjective claim.
The other thing I love about the QY7 is its battery life. It would work way longer than the Backbeats. I haven't measured the battery life properly, but according to my experience it would go for more than 8 hours without a charge. I listen to podcasts while commuting to work and that is about 1hr in total. I would 90% battery left according to the battery status shown on the iPhone for the earbuds a day after fully charging the battery of it. If this is accurate, it could be as high as 10hrs. It could be that these earbuds carry a larger battery than the Backbeats because they are a bit larger. Also it appears that the earbuds turn themselves off after a while if it is not connected to a device. Not the most amazing design but I'm up for longer battery life.
