If you're focused on gaming, the Razer Kraken with its excellent microphone would be a better choice as it's designed for immersive gaming experiences. However, if you're looking for versatility and portability, especially for commuting or traveling, the Soundcore Space A40 earbuds are a better fit due to their compact design, active noise cancellation, and longer battery life. The Soundcore earbuds are also sweatproof and come with wireless charging, which makes them suitable for exercise, whereas the Razer isn't suited for high-moisture environments. Keep in mind though, that the Kraken is a wired headphone, which could limit mobility, while the Soundcore A40 offers a wireless connection for greater convenience. Give Feedback

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."

Sam Smart | May 2023
"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."
