The AKG K712 Pro are open-back headphones, which means they offer a larger soundstage for an immersive listening experience but have no noise isolation, making them unsuitable for noisy environments or commuting. They're wired, so while you get a stable connection with no latency, you lack the convenience of wireless use. The Soundcore Space A40 are closed-back earbuds; they have a smaller soundstage but greater portability and offer wireless freedom with active noise cancelling to block out ambient noise. They also feature a built-in mic for calls and come with secure fit accessories for exercise. Consider the AKG K712 Pro for serious home listening and the Soundcore Space A40 for versatile use including travel and exercise. Give Feedback

Sam Smart | May 2023
"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."
