new ones after every 6-12 month
My current wireless buds are 3 years old, almost used daylie and still running fine with good battery life etc. That's much longer than any headphones with cable lasted for me and I always bought quality headphones. The wire always broke at some point.
On the other hand there's more electronics and batteries inside wireless headphones so yeah...
( I still like the headphone jack and I'm sad that it's almost gone )
