Jaybird Sportsband SB1 Battery Almost Exploded

I got my Jaybird SB1s just over a year and a half ago and sadly tonight they died. I was charging them and as you can see in the above picture the battery has swollen and caused the casing to pop open. This is very disappointing since I have seldom used them and the battery is not replaceable, I guess I was lucky that I spotted problem before the battery exploded.

So I guess I am in the market for some more wireless headphones, this time I will be avoiding Jaybird and looking for something with better performance and replaceable batteries.
