If you prioritize gaming and are okay with wires and a heavier set, the Razer Kraken V3 headphones have good gaming and TV scores, a boom mic for clear communication, and virtual surround for a more immersive experience. On the other hand, if portability, noise isolation, and wireless features are important, especially for commuting or air travel, the Soundcore Space A40 earbuds offer excellent noise isolation, a lighter build, and support for wireless charging with a longer battery life, but they have poorer performance for gaming and professional calls.

"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."

"The Anker Soundcore Space A40 is an excellent deal if you want affordable noise canceling earbuds with great sound. The baseline frequency response is enjoyable, and the many EQ presets to choose from plus the ability to customize your sound profile makes it good for pretty much anyone. The noise canceling is quite good, and the many ear tips to choose from ensure a good fit for the noise canceling and isolation to do its job."
