Any reason why Kraken Pro V2 only last a year?

The year is 2017 and it's February. I had just gotten further involved in PC gaming. I had gotten a Blackwidow Chroma for Christmas and wanted some more gear, specifically headphones. After some browsing I decided on the Kraken Pro V2, as it was within my price range and was what I needed. I get them, have issues of echo, whatever. February 2018, a single year, comes around. They crap out for no reason and after contacting support I got a replacement pair. February 2019, a single year almost to the date, and they start to slowly go out again until they're unusable. Why is it that two pairs of $80 headphones are only able to last a single year each with careful treatment? Improper treatment causing that would make sense, but never throwing them around, never using them outside, being careful about liquids, etc., leading to them going out is unreasonable. Has anyone else had issues of their headphones lasting an unreasonably short amount of time? It's frustrating to say the least when on a tight budget.
