The Beyerdynamic 770 Pro (80 ohm) is significantly less expensive and offers great sound quality, comfort, and build quality, making it a good choice for listening to music, TV and video, but with limited portability and no noise cancellation. The Thieaudio Monarch Mk II, while more expensive, provides superior overall sound quality, a slightly better soundstage, and higher portability, but with no substantial advantage in noise isolation. Neither option includes active noise cancelling or wireless features. If budget is a constraint and you don't require top-of-the-line sound fidelity, the Beyerdynamic might be more suitable, while the Thieaudio should be considered if you're seeking the best sound performance and can justify the higher cost.

"Altogether, when you consider its accessible price tag, the performance, the build, and its outstanding comfort, I think that the DT770 Pro is fantastic option for anyone looking for a closed-back headphone in the sub-$1,000 range, and I can confidently give it a strong recommendation."

"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."
