Choosing between the Sennheiser Momentum 4 and Soundcore Space Q45 depends on your priorities. The Sennheiser Momentum 4 offers superior sound quality and comfort, which is essential for an immersive listening experience, but at a premium price. They also have better microphone quality, making them suitable for calls. On the other hand, the Soundcore Space Q45 offers good value with decent sound quality at a midrange price. If you’re looking for features like multi-device pairing, the Momentum 4 might be the better option, though they do not support LDAC like the Q45. Additionally, the Q45 has a unique feature that allows you to adjust the ANC's aggressiveness on the fly. If budget is less of a concern and you want top-tier sound and comfort, the Momentum 4 could be the choice, but for those who are more price-sensitive and still want good quality sound and features, the Space Q45 could suffice.

Sound Guys

Christian Thomas | January 2023
"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."

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."
