The headphones did not change in either their look or their functionality after being used for a period of six months. They started to sit softer, and all in all, it was simple to get acclimated to how they were sitting. The charge is still retained for a significant amount of time and can be restored in the same short amount of time. Depending on how heavily I use my phone, I normally charge it every two to three days. In most cases, you are able to sit continuously throughout the day and only need to charge at night.
