If sound quality is your primary concern, especially for music, the Thieaudio Monarch Mk II offers a superior auditory experience, but it lacks wireless connectivity and is pricier. On the other hand, the Sennheiser Momentum True Wireless 2 provides a good overall sound with the convenience of wireless functionality, suitable for exercise and travel, and features like active noise canceling, and they come at a more affordable price. Keep in mind that the Thieaudio Monarch Mk II, while wired and without active noise canceling, has better soundstage and is deemed better for TV and video due to truer sound reproduction.

What HiFi? | November 2022
"They are more comfortable and nicer to use than their predecessors, battery life is better and noise-cancelling is now included as part of the package. They’re easy to live with and you could happily listen to them for hours on end without reaching for the pause button. If your budget allows, your ears will be handsomely rewarded."

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."
