If you prioritize sound quality, especially for music, the Thieaudio Monarch Mk II outperforms the Soundcore Space A40, and also scores higher for TV and video enjoyment. However, the A40 is designed for wireless use with features like active noise cancelling, making them a good fit for air travel and exercise, while the Monarch Mk II is wired and lacks noise cancellation, which could be limiting for active use. The A40 is more suitable for use during calls due to its integrated microphone and wireless capabilities. Consider the Monarch Mk II for the best audio fidelity, but choose A40 for convenience, portability, and a wider range of usages at a lower price. Give Feedback

Sound Guys

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."

Audiophile On | August 2021
"No other earphone I have listened to in the past 12 months has given me as much joy as the Thieaduio Monarch MKII. One of those IEMs will make you question where we can go from here. The sound is jaw-dropping, leaving you wanting more and more. It makes you want to run through your entire music library and reevaluate. It makes you not feel bad about paying full price for them, especially in a hobby where buyers' remorse is genuine. For me, it's top tier, rivaled by a few but not surpassed."
