I've had the same airpod products before, but these seem to be very flawed. They do not always keep connection with my phone via bluetooth (unlike my previous ones), they also tend to have an echo like sound from time to time. Meaning that the right and left ear are not synced together well. I was very happy with my previous pair before I wrecked them. These on the other hand have been well maintained and taken care of, but after these last 4 weeks or so, I am very disppointed considering the cost!
