The Koss KSC75 will save you money and offers an open-back design, which provides a more natural sound stage but allows sound to leak and offers less isolation from ambient noise. They also have ear hooks instead of a traditional headband, some might find them more comfortable for long periods, while others may prefer the secure fit of headband styles like the Soundcore Space Q45. In contrast, the Soundcore Space Q45, while more costly, features active noise cancellation, wireless connectivity with LDAC support for higher quality audio over Bluetooth, and an integrated microphone. These added features make it a versatile choice for different environments, including noisy settings, and the convenience of wireless connections, along with the benefits of a closed-back design for better noise isolation and bass response.

Crinacle | June 2022
"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."

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."
