I have had my Nokia BH-905 headphones since 2010. They have been working perfectly. The sound is great and the battery life is still very long. Unfourtunaly since one year, the outside has started to rapidly degrade, so I have decided to refurbish them, ( try to atleast ;) )
Leather, leather glue and thread have been ordered! I found a place where you could order 200g mixed leather very cheap. Now it will be exciting to see which colors they will send. Hopefully something that fits the headphones well. I am crossing my fingers and looking forward to next week.
