The HifiMan Arya Stealth headphones and the Thieaudio Monarch Mk II earbuds both cater to high-end audio experiences. If you prefer open-back headphones for a more spacious soundstage and own or are willing to invest in a dedicated amplifier to get the best performance out of them, the HifiMan Arya Stealth might be ideal for you. However, if you are looking for versatile in-ear monitors that are easier to carry around and don't require an amplifier, the Thieaudio Monarch Mk II would be more suitable, although they come at a slightly higher price point than the Arya Stealth. Additionally, the Arya Stealth's open-back design may not be as suitable for noisy environments compared to the Monarch Mk II's closed design. Give Feedback

Eric D Hieger | October 2022
"The Arya can easily be end-game headphones for 99% of consumers, satisfying most audio desires. Priced well above USD$1000, the Arya are obviously and gloriously not for the mass market consumer; they are designed and built by enthusiasts for enthusiasts – especially those who view their expenses on this level of gear as investments."

"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."
