They have a warm default sound profile, with cozy-sounding vocals and lead instruments. The companion app includes a graphic EQ and presets if you prefer a different sound, but unlike the Google earbuds, they don't come with any virtual surround sound features. They aren't the best option for workouts since they don't have stability fins or a very stable fit and may slip out of place if you move your head around a lot. The Anker Soundcore Liberty 4 NC Truly Wireless are a good alternative if you want similarly-performing buds with a slightly different shape. Compared to the Space A40's rounded look, the Liberty 4 have a more traditional stem design that some users may find preferable. The Liberty 4 also bring a touch more bass, though this muddies their reproduction of vocals and instruments a bit. Battery life comes in at around nine hours in-ear, with the charging case pushing the total up to 28 hours. Those figures fall to seven and 24 hours with ANC enabled, or five and 15 hours with spatial audio turned on. The Liberty 4 support both wireless and fast charging, with the latter providing up to three hours of listening from 15 minutes on charge. The M3 part of the name aligns them with Sony’s excellent WH-1000XM3 headphones from 2019, which have class-leading sound and noise cancelling. The true wireless earbud version inherits the same noise cancelling chip and are almost as effective, reducing or eliminating train, road and plane noise, leaving you free to listen to your music at lower, more comfortable volumes. While the Anker Soundcore Liberty 4 NC falls short of the besting the EarFun’s noise-cancelling, it edges its rival for audio. They elicit more clarity from the midrange, with vocals that sound a touch more refined and detailed on the Anker.
Anker claims 10 hours per charge and 50 hours with the case, though that’s not the whole picture. The headline figure refers to listening without ANC. With ANC it falls to 8 hours (40 overall), and with LDAC and ANC Anker says it’s 5 hours (25 in total). From the tests I carried out, the Anker Soundcore Liberty 4 NC falls short. They have an AirPods-like design with stalks but a well-fitting traditional silicone ear tip that provides solid noise isolation. They’re comfortable for hours, come with five different sizes of earbud tip and are IPX5 sweat-resistant, so fine for using on a run.For starters, you can choose between adaptive active noise canceling, which will adjust to your environment, or controlling it manually. You’ll also find two versions of transparency mode (vocal and full), and in a parody of Sony’s loaded control system, even a version designed to adapt to different transportation modes like trains, planes, and various automobiles. Wind Buffering is one of my favorite extras, effectively keeping your ears from getting blown out while using transparency mode in a breeze. These comfortable and well-built buds have a warm sound profile out of the box, but you can fine-tune their sound to suit your tastes using their companion app's graphic EQ and presets. You can also use the app to switch to LDAC codec to stream Hi-Res content. That said, their mic has poor recording quality. The mic captures speech that sounds far away and sibilant, which can be a dealbreaker if you take a lot of calls. However, if you're just looking to listen to music, these wallet-friendly earbuds are worth a look. Using the 'JLab Signature' EQ, they have a bass-rich sound profile that delivers a bump of extra punch and boom to mixes. The extra bass doesn't overwhelm vocals and lead instruments, so they're still versatile enough for most types of audio content. They also don't come with a companion app, meaning that the only EQ options you have are the three EQ presets built into the earbuds, which gives you significantly less control over the audio than the JBL Vibe Beam True Wireless. However, they last longer than the JBL on a single charge. Phone call quality has been muddled. Clarity can be muffled, the other person struggled to hear me in noisy places but when it is quiet, the Liberty 4 NC works fine. The quality here is average for a true wireless, though as the review was published, there was an update to improve call performance. I’ll try it out again and will revise the review if my opinion changes. Sound Quality Listening to a Spotify stream at 50% volume for an hour saw the Anker Liberty 4 NC fall to 80%. That indicates 5 hours with ANC on. In LDAC mode it was between 60 – 70%, which is about 3-4 hours before another charge is needed.
The Buds+ sound really good producing detailed, balanced audio with a good amount of low-end punch. They can be cranked up to be uncomfortably loud, and come with a basic preset equaliser. They sound far better than most rivals at this price, but can’t match the most expensive earbuds for pure sonic quality.Compatibility. It's important to consider compatibility when selecting a wireless phone charger since it can only support certain wireless charging standards such as Qi. Be sure to verify that your phone is compatible with the charger you're considering to avoid any issues with charging.
There are plenty more to go around, though, including an earbuds finder, a latency reducer for gaming, multi-point audio to connect to two devices at once, and LDAC high-resolution streaming for supported Android phones (though you can’t use LDAC and multipoint pairing together). The sound profile makes a great first impression too, which mostly bears out too across extended usage. Bass is punchy and energetic, if not exactly spacious, but on the whole there’s a decently-sized soundstage with both buds in your ears. Most Anker headphones are compatible with the Anker Soundcore app, which offers a graphic EQ and presets so you can adjust your headphones' sound to your liking. You can also remap controls and adjust the active noise cancelling (ANC) level to suit your needs. Then again, their flaws are not completely ruinous. It's better to have a capable pair of headphones that look lame than a stylish pair that sound awful, and if you're willing to spend a minute or so tweaking the app, the Soundcore Liberty Air 2 Pro punch above their weight again and again.
Can you control music from the earbuds?
To begin with, Bluetooth connectivity is at the stronger end. Using an iPhone 11, we found reception stayed consistent across rooms and through various walls, with no skips or dropouts, and this proved to be the case while on the go too. Pairing is also easy, with the buds connecting immediately to the last device used when removed from their case. The app itself is simple and clear to traverse, as well as responsive. The wear sensor feature works, though I’ve noticed it doesn’t resume as often after it pauses. Brilliant sound, excellent noise cancelling and solid connectivity, complemented by solid battery life and an attractive design, the WF-1000XM3 are still the best-sounding true wireless earbuds.
Although not all of their headphones support this codec, a couple of their latest headphones, like the Anker Soundcore Liberty 3 Pro Truly Wireless, support LDAC, designed for Hi-Res audio. Support for this codec is also uncommon in truly wireless headphones. The indicator light on the dongle will display a constant purple which indicates the pairing was successful. It's not even a particularly basic implementation of the tech. ANC comes in three flavors — Transport, Indoor and Outdoor — as well as in a Custom option that lets you adjust the noise-cancellation effect's intensity.
How well does the Anker Soundcore Liberty Air 2 Pro cancel noise?
Still, while that might be an underwhelming result for non-ANC buds, it's a pretty good showing when you factor in the extra drain of constant noise-cancelling. They even narrowly beat the AirPods Pro, which lasted 4 and a half hours in our testing, though Sony's WF-1000XM3 seem to be the overall ANC earbud winners on longevity. The good news is that while this is the default sound, it's not the only one. The Soundcore app serves up customization in a couple of different ways, the more interesting being its "HearID" feature. This plays a series of beeps to test how well you can hear different frequencies at various volumes and uses the results to craft a sound profile that's specific to you. In the midrange and treble, the Anker retrieves more detail and defines instruments and voices with more precision, making the Air Pro 3 a little dusty and dull by comparison. Speaking of which, Siri and Google Assistant are accessible on the Life A2 NC and operate fairly well. Anker’s mic array does a standout job with speech recognition, grabbing every word for both Apple and Google’s AI bots to fully comprehend. Aside from the activation delay, my verbal inquiries were met with speedy results. But be wary when enabling the feature, as the beep noise that signals you to speak is uncomfortably loud, no matter the set volume. Anker Soundcore Life A2 NC review: Active noise cancellation
