Budget wireless earbuds almost always come with some form of compromise, and the most common one is noise cancellation. Soundcore by Anker turns that equation on its ear with the Space A40 buds, and Amazon turns the Space A40 into the best $49 buds on the market with this 39% off deal.
The standout feature in the Space A40’s ANC system is its adaptive rather than fixed cancellation. Soundcore claims up to 98% noise reduction, which is unheard of in a pair of sub-$100 buds, much less ones selling for just $50. The earbuds read external noise in real time and automatically adjust the cancellation level to match the environment, moving between settings depending on whether you’re indoors, outdoors, commuting, or on a flight.
Buds That Work for You
Most budget and mid-range earbuds offer a handful of preset ANC modes that require manual switching. The A40 handles that automatically, which matters most when your environment changes during a commute or a long travel day.
The single-charge playtime for the Space A40 is 50 hours between the earbuds and the case, with 10 hours of single-charge listening per earbud. More useful for daily use is the fast charging: 10 minutes in the case returns 4 hours of playback, which covers the morning-ride rescue scenario when you forgot to charge overnight. The case itself supports wireless charging, so the A40 works with a Qi pad if you’d rather not deal with a cable — another highly rare feature in a $50 pair of buds.
High-Level Sound
The Space A40 buds support LDAC, Sony’s high-resolution audio codec that transmits up to three times the data of standard Bluetooth to preserve more of the original recording. That’s relevant if you’re streaming from a service that provides lossless or high-res content and pairing with an Android device that supports LDAC output. For standard streaming it won’t change much, but for users who care about audio fidelity, LDAC support at this price is a stone-cold steal. The double-layer diaphragm drivers are built to make use of it, delivering a sound profile with strong low end, clear midrange, and defined treble.
Add the comfort and ergonomically pleasing design of the Space A40 to the high-performing ANC, long battery life, and ability to stream lossless content, and the $49 price tag that’s good while this 39%-off Amazon deal is running is genuinely hard to believe. Easier to believe — this deal is selling out quickly, so don’t hesitate.
