The Razer Kraken excels in gaming and mic quality, so if you're a gamer or spend a lot of time on calls, this could be a good budget pick. However, it's not wireless and may not be as suitable for travel or exercise. On the other hand, the Sennheiser 450BT offers wireless connectivity, better portability, and active noise cancelling which makes them ideal for commuting and air travel. While both share similar overall sound quality, Sennheiser 450BT has higher scores for use during calls and meetings, TV and video, and is more versatile if you plan to use them outside the gaming environment.

PC Gamer
Rob Dwiar | March 2019
"Generally the Kraken is a very comfortable headset and there’s nothing that really identifies it as anything else. All in, the Kraken performed exactly as I’d expect a premium, designated gaming headset to perform: performing well in game audio, though not quite with the same quality of those headsets further up the price scale."

"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
