If you're looking for wireless convenience and active noise cancelling for travel or noisy environments, the Soundcore Space Q45 might be better suited for you, and they're more affordable. They also have a much longer battery life, which is beneficial for extended use without the need to recharge. However, if sound quality is your top priority and you prefer earbuds over headphones, the Thieaudio Monarch Mk II delivers superior audio performance, albeit at a higher price. Note that the Monarch Mk II lacks wireless capability and active noise cancelling, but they come with different driver types for detailed sound reproduction. Give Feedback

Sound Guys

Riley Ballantyne | June 2023
"The Anker Soundcore Space Q45 is a great pair of active noise canceling (ANC) headphones, and the $150 USD price tag only sweetens the deal. Unlike many mid-tier wireless headphones, the Q45 microphone system rejects quite a bit of background noise, making this a great work headset too."

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."
