The 1More Sonoflow generally costs less than the Sennheiser 450BT and offers better overall sound quality, longer battery life, and includes a codec for high-quality audio over Bluetooth, which the Sennheiser lacks. However, the Sennheiser has higher quality for calls and meetings, better performance for TV and video with low latency technology suitable for gaming, and more robust active noise cancelling. Choose the Sonoflow if you prioritize sound quality and value, but consider the 450BT if you need better call quality, plan to use them while watching TV or gaming, or frequently travel and need superior noise cancellation.

Michael | January 2023
"The SonoFlow is cheap and fun, without going too far into being overly warm or annoyingly grating, or sharp sounding. The ANC features are lovely with strong app integration and excellent battery life."

Lily Katz | March 2022
"The Sennheiser HD 450BT is a very good pair of headphones for the price, noise canceling is good and sound quality is great—quite rare at this price point. Like any product, this headset isn’t without its faults."
