The Earfun Air Pro 2 earbuds are more affordable and feature active noise cancellation, making them suitable for commuting or use in noisy environments. They are wireless and offer more convenience for everyday use. In contrast, the Thieaudio Monarch Mk II, though more expensive, provides a higher sound quality with a hybrid driver configuration, which can be better for audiophiles and those who prioritize audio fidelity. The Monarch Mk II lacks active noise cancellation but includes detachable cable ear hooks and is capable of balanced audio, which can appeal to those who use high-quality audio players or amplifiers.

Peter Susic | September 2021
"There’s a lot to like about EarFun Air Pro 2. The best thing about them is the active noise cancellation, which works almost as well as the best true wireless earbuds out there. The audio quality is funky but enjoyable. Good dynamics and a wider soundstage save its presentation. Everyone, apart from the most diehard audiophiles, should be happy with it."

"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."
