If you prioritize call quality and versatility for different activities, including air travel and watching TV, the Earfun Wave Pro stands out with very good performance in these areas and offers features like active noise cancelling and a long battery life. On the other hand, if your focus is on the absolute best music listening experience, the Thieaudio Monarch Mk II might be more suitable, despite its poorer performance for calls and gaming. The Monarch Mk II boasts top-tier sound quality but lacks wireless capability and some convenience features like an app equalizer and battery life. Consider also the form factor: the Earfun Wave Pro is an over-ear headphone suitable for longer listening sessions at home or while traveling, while the Monarch Mk II, a wired earbud, is more portable but may not be as comfortable for extended use. Remember, the Thieaudio Monarch Mk II comes at a high-end price, which is typically significantly more than the Earfun Wave Pro. Give Feedback

"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."
