I bought almost exactly the same model (Kraken X, without ‘Lite’) 5–6 years ago, and it’s worked perfectly throughout that time. It’s even sustained some damage from a few drops and cat bites, yet the sound quality (both input and output) hasn’t suffered. I had to buy a new one because the cable snapped. I’ve gone for this model again mainly because of the noise cancellation, which works brilliantly, and because I don’t like wireless Bluetooth headphones, as the quality suffers when using the microphone (due to the Bluetooth, not the headphones themselves). 100% recommended, for all kinds of uses. They’re in excellent condition, indistinguishable from a new pair – even a refurbished one.
