Yes, the battery life on the Space A40 is genuinely impressive. In our testing, we consistently got 9-10 hours per charge with ANC on, which matches Soundcore's claims. The 50-hour total means you can go a full week between charges with normal daily use. It's perfect for travelers or anyone who hates charging small devices frequently.
The sound quality is very good for the price, with rich bass and clear enough highs. It won't match the sonic refinement of premium options from Sony or Cambridge Audio, but most casual listeners will be very happy with it. The app-based EQ is a nice touch that lets you tailor the sound to your preferences.
They're decent for workouts with the IPX4 water resistance rating and secure fit. They should handle sweat and light rain without issues. However, if you do very intense workouts where earbuds often fall out, you might want to consider sport-specific earbuds like the JBL Reflect Aero or Jabra Elite 8 Active with more secure wingtip designs.
The Soundcore Space A40 is the best wireless earbuds for battery life in 2026. If you're tired of constantly charging your earbuds, the 50-hour total battery life is a game-changer. But these aren't just a one-trick pony — they also deliver solid ANC, good sound quality, and wireless charging at a very competitive price. For the price, the value is outstanding. If long battery life is a top priority, these are the earbuds to get.
