Anker Space A40 Review – The Design

Anker Space A40 review

The exterior design looks like Anker Life A3i and Anker Life Dot 2. Most materials are plastic both inside and outside and also look a little robust. They are designed without stems, nice, compact, and super comfortable to wear for hours without fatigue on my ears. With the standard oval shape of earbuds and the Soundcore providing multiple ear tip sizes, you can choose the right size of ear tips to perfectly fit your ear canal. Wearing the earphones in the right position and angle will superior comfort and ANC performance, and also this will give great noise isolation too.

In terms of durability and water-resistant, the Anker Space A40 is rated IPX4. This number is not outstanding, but it can protect the earbuds from light rain and some water splashes. That means these wireless earbuds are great for some activities that make you sweat a lot such as mini-marathon, or hard-working out, and surely it can’t wear for swimming. If you need more rated in terms of waterproof look over these wireless earbuds and look for others like Lypertek PurePlay Z3 2.0 or Anker Soundcore Liberty A1, both offer an IPX7 rating of water-resistant.

The charging is capsule-shaped and compact in size, 2.67 x 1.74 x 1.12 inches, which is small enough to easily slide into the pocket. They are smaller than Jabra Elite 7 Pro and cheaper, but sturdy built with a soft-closing lid. There are three LED lights in the front panel to indicate the charging status and the remaining battery.

How’s about the battery life of the Anker Soundcore Space A40 wireless earbuds?

Anker Soundcore Space A40 review

Very impressively, the Space A40 gives a maximum of up to 10 hours of listening to music continuously (ANC off). Indeed as you know, the number of hours of playtime is not accurate, it depends on the volume level, turn-on or turn-off ANC, and other factors. The 10 hours is a specification from Soundcore. Not serious, however, the Anker Space A40 gives playtime not less than 6 – 7 hours even if you turn on ANC and use almost max volume. Personally, this number is quite impressive.

Talking about the charging case, the case provides 5 times. That means you can get playtime of up to 50 hours in total. In case of earbuds’ battery run out, you just put the earbuds in the case for 10 minutes, and you get another 4 hours of playtime, amazingly and touching.

Moreover; the Space A40 give more convenient by being compatible with wireless charging too.


The good thing is these Bluetooth wireless earbuds can connect to two devices at the same time. The multi-point connection let you connect your phone and other Bluetooth devices simultaneously. These are quite good for wireless earbuds under $100 and easy to switch to take the call.

These wireless earbuds come with Bluetooth 5.2 and support SBC, AAC, and LDAC codecs. Recording to the specs, the Bluetooth range is moderate and is around 10 meters or 33 feet without obstacles. But from our testing, I can get the signal about 25 feet indoors and maybe 40 to 45 feet outside. You can also switch between using one or two earbuds.

One thing that I found, LDAC is not compatible with Bluetooth multipoint, I tried to connect to two devices and it didn’t work, I don’t know where I made a mistake

When talking about control functionality, the Space A40 is touch control on the back of the buds. The touch panel is respond quite well. The controls can adjust via the app, you can define any function for one tap, double tap, and also tap and hold.

Anker Soundcore Space A40 Wireless Earbuds – The Sound Quality

Anker Space A40 - Great sound quality under $100

The sound quality of the Anker Space A40 is not excellent, the audiophiles will not impress the output as enough. But these wireless earbuds provide so good sound for under $100 price. With the double-layer diaphragm drivers, the Space A40 will deliver highly-detailed sound. You can hear all frequency responses from these wireless earbuds. The bass is strong enough that make you feel the rhythm of the drums, but not so strong that it overwhelms the bass.

The mids and highs, I feel that they are a little dull and lack clarity. But good luck, the Anker Space A40 allows you to set the sound profile via the app. You can go through the HearID tuning procedure in the Soundcore app. After setting something in the app, I feel an immediate improvement output of the sound. I noticed the clarity that was missing was restored.

The Soundcore app provides EQ presets and also lets you tweak the EQ too. I so much like this. The app has a full 8-band graphic equalizer and the ability to keep your own combinations too.

The overall noise cancellation of the Anker Soundcore Space A40 is excellent over the price. Some cheap wireless ANC earbuds may have some noise like humming or muffled sound etc. Especially use ANC without music. But what are these earbuds do, they exceed expectations.

The ability and diversity of the Space A40’s ANC are very good, and although not as good as Sony WF-1000XM4 which is much more expensive.
