If you want superior battery longevity and adaptive noise cancellation that feels seamless for long commutes, choose Anker Soundcore; if you need the latest connectivity standards like Bluetooth 5.4, lossless audio codecs, and Auracast support for modern devices, choose EarFun Air Pro 4.
• Anker Soundcore Liberty 4 NC: Delivers an impressive 50-hour total battery life with a robust 98.5% noise reduction claim, but uses the slightly older Bluetooth 5.3 standard.
• EarFun Air Pro 4: Offers cutting-edge features including aptX Lossless, LDAC, and Bluetooth 5.4 with a 52-hour battery, though its single-charge duration is shorter than the Anker's.
• Who picks Anker: The listener who prioritizes all-day endurance and consistent, high-level silence over technical audio codec variety.
• Who picks EarFun: The audiophile or tech enthusiast who wants the absolute latest transmission speeds, lossless music fidelity, and social broadcasting capabilities.
The Anker Soundcore Liberty 4 NC is built for the person who treats their earbuds as a primary tool for escaping the world. Its standout feature is the Adaptive ANC 2.0 system, which claims to cancel up to 98.5% of external noise. This isn't just about blocking out a fan; it is designed to handle the chaotic shifts of real environments, from a bustling train to a windy commute, by making real-time calculations based on your specific ear canal shape. If you spend hours in transit or work in a noisy office, this level of active isolation is the first thing you will notice.
For the audio purist, the Liberty 4 NC offers a flexible sound experience without requiring a degree in engineering. The 11mm custom-tuned drivers are paired with LDAC technology, which transfers three times more data than standard Bluetooth connections. This allows for Hi-Res wireless audio that preserves detail in complex tracks. Furthermore, the HearID 2.0 feature creates a personalized sound profile for your ears, or you can simply toggle through 22 presets and a fully adjustable EQ. It gives you control over whether you want punchy bass or crisp vocals without needing external software.

This model is also a powerhouse for those who hate charging their devices constantly. In normal mode, you get 10 hours of playback on a single charge, and with the case included, that extends to a massive 50 hours. Even with Active Noise Cancellation turned on, you still get 8 hours per charge, extending to 40 hours with the case. The inclusion of USB-C quick charging means a 10-minute charge provides enough power for a significant listening session. With IPX4 water resistance, these earbuds can handle sudden downpours or heavy sweat during workouts without issue, making them a reliable companion for both travel and fitness.
The EarFun Air Pro 4 targets the user who demands the most current technology available in the consumer market. It utilizes Bluetooth 5.4, which is two generations newer than the standard found in many competing models. This newer protocol promises ultra-low power consumption and a more secure connection, which is crucial if you switch between multiple devices frequently. The addition of Multipoint Connection allows you to stay connected to two devices simultaneously, meaning you can answer a call on your phone while your laptop continues playing music without dropping the stream.
A major draw for the audiophile here is the Qualcomm Snapdragon Sound platform. This includes support for aptX Lossless and LDAC Hi-Res Audio, ensuring that the signal reaching your ears is as close to the original studio master as possible. The earbuds feature a 10mm dynamic driver with a frequency response that reaches up to 40 KHz, offering a wider range of treble detail than many competitors. If you listen to high-quality files or stream from services that support lossless audio, the difference in clarity and separation will be immediately apparent compared to standard compression formats.
Social connectivity is another area where the EarFun Air Pro 4 shines. It supports Auracast Broadcast Audio, a feature that lets you tune into local broadcasts or share your audio experience with others nearby. This is ideal for gyms, parks, or public spaces where you might want to hear a podcast or music shared by a friend without passing around a single device. The battery life is equally competitive, offering 11 hours on a single charge and up to 52 hours with the case. While the case is slightly larger due to the plastic construction and glossy finish, the 10-minute fast charge provides two hours of playtime, keeping you moving quickly.
• Best for gym: Both have IPX4 ratings and fit securely, but the EarFun Air Pro 4's Auracast feature makes it unique for group workout environments where you might want to sync with a trainer's broadcast.
• Best battery life (total): EarFun Air Pro 4 wins with 52 hours total, while Anker Soundcore offers 50 hours, though Anker leads in continuous playback time per charge with 10 hours versus 11 hours for EarFun.
• Best for calls: Both utilize 6-microphone arrays with AI algorithms, but EarFun specifies the use of Qualcomm cVc 8.0 technology for enhanced vocal clarity in noisy settings.
• Best audio fidelity: EarFun Air Pro 4 takes the edge with aptX Lossless support alongside LDAC, whereas Anker focuses on LDAC and HearID personalization.
• Best connectivity: EarFun Air Pro 4 uses Bluetooth 5.4 with Google Fast Pair, offering faster pairing and better stability than the Bluetooth 5.3 found in the Anker Soundcore Liberty 4 NC.
• Best for quiet travel: Anker Soundcore's claim of 98.5% noise reduction and its Adaptive ANC 2.0 make it a strong contender for maximum silence in unpredictable environments.
• Best value for tech lovers: If you want the newest features like Auracast and the latest Bluetooth standard, the EarFun Air Pro 4 is the clear choice.
• Best for simplicity: Anker Soundcore offers a straightforward, reliable experience with proven ANC performance and a longer track record of stable connectivity.
In my opinion, I would buy the EarFun Air Pro 4 because it represents the future of what these earbuds should be. The combination of Bluetooth 5.4, aptX Lossless, and Auracast support gives it a versatility that the Anker Soundcore cannot match. While the Anker is an excellent product with fantastic battery life, the EarFun offers a more comprehensive package for someone who values high-fidelity audio and modern connectivity standards. If you are looking for the best bluetooth headset for gym sessions where you might want to connect to public audio feeds, or simply want the crispest sound possible with the latest codecs, the EarFun Air Pro 4 is the winner.
Both models feature IPX4 water resistance, which protects against sweat and rain. The Anker Soundcore Liberty 4 NC has a slightly longer continuous playtime per charge, while the EarFun Air Pro 4 offers a newer Bluetooth connection that may reduce dropouts during movement.
Yes, both products require their respective companion apps to access advanced features. The Anker app allows you to use HearID 2.0 and adjust the EQ, while the EarFun app lets you customize the sound profile and manage the Auracast features.
Both earbuds come equipped with 6 microphones. The Anker uses beamforming mics with an AI algorithm, while the EarFun Air Pro 4 pairs its 6 mics with Qualcomm cVc 8.0 technology to isolate voice and eliminate background noise effectively.
The EarFun Air Pro 4 offers 11 hours of playback on a single charge, whereas the Anker Soundcore Liberty 4 NC provides 10 hours. However, the Anker's case extends the total usage to 50 hours, while the EarFun case extends it to 52 hours.
