The 1More Sonoflow and Soundcore Space A40 both offer good sound quality for their price range, but the Sonoflow, being over-ear headphones, generally provide better noise isolation and may be more comfortable for longer periods of usage, which is ideal for air travel and focused listening sessions. Their built-in battery also lasts significantly longer on a single charge. On the other hand, the Soundcore Space A40 earbuds are smaller and more portable, with earbud carry size being medium compared to the large carry size needed for the Sonoflow. Additionally, the Space A40 offers wireless charging and is sweatproof, making them a better companion for exercise. If active noise cancelling is a priority for you, the A40 outperforms the Sonoflow in that area, which can be crucial for blocking out ambient noise in various environments. Therefore, if you're looking for something more compact for everyday use and exercise, with added features like sweat resistance, the Space A40 might be the better option despite the slightly higher price point. However, for home or travel use where comfort and battery life are key factors, the Sonoflow may be the better choice despite the lack of wireless charging and active noise cancelling. Give Feedback

"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."

"The Anker Soundcore Space A40 is an excellent deal if you want affordable noise canceling earbuds with great sound. The baseline frequency response is enjoyable, and the many EQ presets to choose from plus the ability to customize your sound profile makes it good for pretty much anyone. The noise canceling is quite good, and the many ear tips to choose from ensure a good fit for the noise canceling and isolation to do its job."
