Frequently asked questions
Does the Space A40 work with both iPhone and Android?
Yes. Bluetooth 5.2 connects to all devices. However, Android users get the most out of LDAC hi-res audio—iPhone listeners will use standard AAC codec, which is still excellent for casual listening.
How long does it take to fully charge the earbuds and case?
Earbuds charge fully in about 2 hours from the case. The case itself recharges in 2 hours via USB-C or wirelessly (around 3-4 hours on a wireless pad). A 10-minute quick charge on the earbuds provides 4 hours of playback.
Is the ANC effective on airplanes and in coffee shops?
Yes. The adaptive ANC targets low-frequency rumble like jet engines and HVAC systems very well. In coffee shops, it reduces steady background noise but you'll still hear conversation—transparency mode is available if you want to stay aware of your surroundings.
Can I use these earbuds for workouts?
Yes, but they are IPX4 rated, which means splash-resistant for sweat and light rain, not fully waterproof for swimming. They're comfortable for running and gym sessions, with a secure fit once you dial in the right ear tip size.
What's the difference between the Space A40 and older Soundcore models?
The Space A40 upgrades adaptive ANC (now targets up to 98% noise reduction), adds LDAC codec support, and extends total battery to 50 hours. The case is also smaller and lighter than earlier generations.
