If you're on a budget and mainly listen to music, the Koss KSC75 are a great value, offering very good overall sound quality. However, they have an open design which doesn't isolate noise well and they're not the best for calls due to poor microphone quality. The Razer Kraken V3 is more expensive, but with very good build quality and a boom mic, it's better suited for gaming and calls. It features a closed design for better noise isolation and also has virtual surround sound, enhancing gaming and movie experiences. Neither are ideal for exercise or travel due to poor portability and noise isolation, with the Koss being less durable and lacking any form of noise cancelling, while the Razer's size and weight may be cumbersome. Choose Koss for casual listening in quiet environments or if price is your main concern, and Razer if you need a versatile headset with a focus on gaming. Give Feedback

Crinacle | June 2022
"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."

"This Razer Kraken V3 is a great headset for gamers who want comfort, surround sound, and software customization for a reasonable price. It's primarily a headset for PC gamers since THX Spatial audio is only supported on Windows. If you want something more multifaceted for multiple systems, this won't be an ideal headset for you. Luckily, there are plenty of competent Kraken V3 alternatives available to you."
