If you're on a tight budget and need headphones for casual listening, the Sony MDR-ZX110 could be suitable; however, they have limited features and only fair sound quality. On the other hand, the Thieaudio Monarch Mk II offers best-in-class sound, excellent build quality, and detachable cables, making them a high-end choice for music enthusiasts. The Monarch Mk II is significantly more expensive, but if sound quality is a priority and you don't need wireless capabilities or active noise cancelling, they might be the better pick. Neither are ideal for calls and meetings or use during exercise, and both are wired, limiting mobility compared to wireless options. Give Feedback

"My opinion about Sony MDR ZX110 is they are the best budget headphones of Sony with top-class sound. Clear vocals, great bass, and balanced sound with low sound distortion. The treble could be sharper, but it's ok. 30 mm neodymium dynamic drivers give clear and precise audio, and an inline remote with a mic give decent call quality. Closed-Back Design also helps to improve sound performance."

"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."
