Product Information

If you need to use a conference app on your computer such as Zoom/Microsoft Teams, please set the input and output of the software as stated below: Reboot the Bluetooth device (e.g., phone or computer). Forget all the previous pairing records on your device and disable Bluetooth.

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. 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. When the battery of the charging case is lower than 60%, the light in the middle of the charging case will turn white for 5 seconds and then go out. Within the comprehensive app, more customisation is available with a personalised function (HearID), default EQ (Soundcore Signature), Custom EQ (where you create your own) and 3D Surround Sound that opens up and widens the soundstage. I find this one reduces the impact of bass and makes music thinner. When resetting the earbuds, make sure the earbuds are properly connected to the charging case, or it may cause the reset to fail. When you place the left and right earbuds in the charging case, there will be white LED indicators that confirm the earbuds are properly connected to the charging case.A couple of minor issues aside, the Liberty 4 are a roaring success, pairing excellent sound with a great range of features and customisation options. Spatial audio is closer to the 1MORE Aerothan premium offerings from Sony and Apple in terms of its efficacy, but certainly adds enough immersion to films and breadth to songs to justify its inclusion. The Anker Soundcore Liberty 4 NC boasts a very effective Wind Noise Reduction mode and there’s also plenty of ANC customisation whether through manual means, to adaptive noise-cancelling with an Environment Detection mode that mutes audio for two seconds while adjusting to external sounds. When I used it, it didn’t do anything, so perhaps leave it aside. As mentioned, the app has many options for customizing the ANC experience, but that's not necessarily an advantage; the best implementations I've tested don't require any user intervention. For what it's worth, the Adaptive Noise Cancelling mode seems to work similarly to the Manual mode at the max level (5). The Transportation mode might be worth trialing depending on your environment, but most people should choose the Adaptive Noise Cancelling mode or the highest manual setting. 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.

LDAC is exclusively supported on Android phone systems 8.0 or above and is not compatible with iOS devices. 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.However, any shortcomings are forgivable when factoring in feature set and price. Ultimately, the Liberty 4 NC are a noteworthy budget option for music lovers that value depth and detail. More from Tom's Guide When the charging case is fully charged, all the white lights will stay on for 5 minutes and then go out. Go into the region of the system, switch to English (United States), and switch the system language to English (United States). The Manual Mode offered the best performance and minimized some high-frequency noises when set at the highest level. The Anker Soundcore Liberty 4 NC takes on an immediately recognisable look with its stem design. The earbuds nestle in the ear, with a range of ear-tips from extra small to large to aid a comfortable fit and tight seal against outside sounds.

Calling and transparency mode aren’t quite on par, but both are serviceable. Sounds are partially obfuscated with transparency mode, but it still keeps you aware of your situation, and I loved the ability to add wind suppression to stop breezes from aggravating my ears on a dog walk. Calls weren’t ultra-clear, but I had no trouble hearing folks and received no complaints over multiple days. I did find the fit a bit loose – the Liberty 4 NC have a habit of pushing out when pushed in – so the seal wasn’t as tight and secure as I’d like it to be. The upside is that they are comfortable to wear, whether over short or long periods of time. The case’s matte exterior feels well-built and good in your hands, reminiscent of the egg-like case you’ll get with Google’s Pixel Buds Pro—one of many competitors that cost double or more at full price. As with the Space A40, I was delighted to find the case is Qi-charging compatible, something plenty of pricier buds skip. If you only want to listen to the audio on the computer, select "soundcore Liberty 4 NC Stereo" for the computer audio. If you need to adjust the volume, adjust both the software and the computer volume.Please note that this doesn't necessarily mean there is an issue with the earbuds but may have something to do with the connected device and environment. Bluetooth signals may be influenced by obstructions, such as walls, pillars, home appliances, Wi-Fi, and more. To ensure a stable connection, we recommend avoiding such obstructions. When resetting the earbuds, make sure the earbuds are well connected with the charging case, or it may cause the reset to fail. When you place the left and right earbuds in the charging case, there will be white LED indicators which confirms the earbuds are properly connected with the charging case.

It's important to note that there may be a slight delay when using Bluetooth headphones, which is a common limitation of Bluetooth technology. In most cases, this delay is minimal and should not impact your experience. However, it's worth mentioning that the delay can be influenced by various factors such as the Bluetooth headphones themselves, the connected device, the audio source, the specific application being used, and even the network conditions.
