If you prioritize wireless connectivity and active noise cancelling for a quiet and versatile listening experience, especially during air travel, the Master & Dynamic MW75-Neuro is a great choice. They also include unique AI technology for tracking focus and planning daily activities, plus they offer high-quality sound and build. However, if the utmost in sound quality is your goal and you do not mind a wired connection without noise cancelling, the Thieaudio Monarch Mk II earbuds provide best-in-class music performance. They lack the convenience features like an app equalizer, optimized controls for Android or Apple devices, and active noise cancelling, but they excel in pure auditory experience. Keep in mind that the Monarch Mk II's are less suited for use during exercise and have lower microphone quality, making them less ideal for calls and meetings compared to the MW75-Neuro.

"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."
