I think OP and you (Because of OP) is mistaken here...The website shows 3 years warranty and you indicated it is going to run out in mid Jan... Does it mean the product was originally bought in January 2018?
The RHA policy is to replace the under warranty earphone with its equivalent that is currently in production. I got this as replacement for MA650 purchased in Jan 2018. However, as I already have Galaxy Buds+, I am looking to sell this one since I won't have use for it in the near future.I think OP and you (Because of OP) is mistaken here...
As far as I know they were released around end of 2018 so it warranty must be around year remaining if OP bought in 2018.
But look like he/she bought it this year and it carry 2 year warranty.
I can be completely wrong here though
