I am the master of my Fate.
The batteries are available as spare parts, but needed a good mechanic hands to replace it.Curious about one thing,all these wireless headphones/earphones come with inbuilt lithium ion battery but is it replaceable.If not then how much is its lifetime assuming 10 hours everyday(like it says on the box "10 hours playtime").

10hrs of playtime per day should last for 3~4 yrs on average
