The Chroma is just more colorful, other than that, the exact same headset. The Kraken 7.1 is a very decent headset. It's not great. It's pretty comfortable, it has alright build quality, the mic isn't bad, it has okay sound quality, but nothing special, and it's not really worth the cost. You're paying a good amount for the Razer brand. The Kingston is okay, but is still a cheaper headset than the 2100, and you get what you pay for.
