A:AnswerAre you, as Bose Support, saying that if I charge this every night the battery will last less than 2 years (500 charge cycles) and that it can't be replaced? These headphones are toast at that point?
Seriously?
You

A:AnswerHello, the cable provided with your SoundLink headphones is 2.5mm to 3.5mm. We'd recommend an 3.5mm to 3.5mm extension (http://amzn.to/2tNbWMy) for your needs, they are available in a variety of lengths. Thanks for the question!
