REAL BLUE/BLUE NC: Is it possible to purchase a replacement battery?

Note: This article is relevant for all REAL BLUE/BLUE NC models.

The battery of the REAL BLUE/NC headphones is permanently installed and therefore cannot be replaced. The battery was designed for longevity so that a battery replacement is not necessary due to decreasing capacity after a long period of use. It still offers approx. 90% performance after 500 charging cycles.
