The Anker Soundcore Space A40 are truly wireless headphones with a powerful adaptive ANC performance. They can block out an outstanding amount of ambient noise that rivals high-end competitors like the Sony WF-1000XM4 Truly Wireless and Sennheiser MOMENTUM True Wireless 3, but you can also switch to one of five manual ANC modes if you prefer a different level of noise isolation. Like the Anker Soundcore Liberty 3 Pro Truly Wireless, they also support LDAC codec for streaming hi-res audio on supported apps. Unfortunately, their mic's recording quality is similarly poor, so if you care about call quality, check out our picks for the best earbuds and Bluetooth headsets for phone calls.
