Reduce Noise By Up to 98%: Space A40 has an upgraded noise cancelling system to block out a wider range of distracting noises. So wherever you go, you'll always have the space you need to focus.
Automatically Tailored Noise Cancelling: Space A40 detects external noises and automatically selects a suitable level of noise cancelling for your surroundings. Enjoy your personal space whether you're indoors, outdoors, commuting, or on a flight.
50 Hours of Personal Space: That's enough playtime to enjoy up to 1,000 songs or 25 movies. The earbuds have a 10-hour single charge playtime, and fast charging gives you 4 hours of listening from a quick 10-minute charge.
Highly Detailed Sound: Thanks to soundcore's pioneering double-layer diaphragm drivers, Space A40 noise cancelling earbuds produce sound with strong bass, clear mids, and bright treble. You can also listen using LDAC mode for Hi-Res Audio Wireless sound.
Comfortable, No Matter How Long You Listen: Space A40 noise cancelling wireless earbuds are smaller than all other soundcore ANC earbuds, are as light as a sheet of paper, and have an ergonomic shape so they fit comfortably in your ears.
soundcore App Support: Download the soundcore app for software updates and access to available features. Personalize your listening with HearID, EQ modes and adjustable ANC settings. OTA firmware updates help keep your earbuds updated.
