Since I cannot access the document you've uploaded, let me provide advice based on my existing knowledge up to April 2023. If price is a major consideration and you are looking for a value option, the Soundcore Space A40 might be the better choice. They usually offer good sound quality and active noise cancellation at a lower price point. However, if you prioritize premium build quality, customization options for gaming, and are willing to invest more, the Antlion Kimura Duo could be superior, especially if it includes a detachable microphone for clear communication. Essentially, choose the Soundcore Space A40 for budget-friendly, everyday use and decent noise cancellation, or invest in the Antlion Kimura Duo for a more premium, versatile experience with potentially better performance in gaming and communication.

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."
