AI Verdict
These are 0.67-ounce wireless earbuds with 11mm dynamic drivers, Bluetooth 5.3, and 10 hours of playback per charge, designed for budget-conscious users prioritizing strong ANC and extended battery li
These earbuds offer exceptional battery life with 10 hours per bud and 50 hours with the case, alongside robust ANC for low-frequency noise, making them a strong contender for travel and quiet listening. However, inconsistent ear tip fit and subpar call quality in loud settings mean they won't suit everyone's daily needs.
If call clarity in noisy environments is crucial, look for earbuds with dedicated voice pickup microphones and advanced environmental noise reduction for calls.

Dimension Scores
The 11mm custom-tuned drivers and LDAC support deliver crisp, detailed Hi-Res audio, which is highly customizable via the app's EQ and HearID 2.0.
Adaptive ANC 2.0 reduces up to 98.5% of noise, performing particularly well against low-frequency rumbles, making it above average for its price point.
While some find them comfortable for long periods, many users report issues with the included ear tips not providing a secure seal or causing discomfort after 15 minutes of use.
Offering 10 hours of playback from the earbuds and a total of 50 hours with the charging case (8/40 hours with ANC), this battery duration is best-in-class.
Best For
- Commuters needing to reduce low-frequency noise from public transport.
- Office workers wanting to minimize consistent background hums.
- Users seeking long battery life for extended listening sessions.
- Budget-focused individuals who prioritize strong active noise cancellation.
Not Recommended For
- Individuals requiring clear phone calls in loud, dynamic environments.
- Users needing a secure fit for intense physical activities like CrossFit or HIIT.
- Those who rely heavily on a natural-sounding transparency mode for situational awareness.
Watch Out For
- The included ear tips are often too thin and flexible, making it hard to achieve a consistent seal, and finding aftermarket tips is difficult due to their specific size and interface.
- Transparency mode is reported to be poor, sounding muffled and not providing adequate situational awareness.
- Call quality in noisy environments is not strong; your voice might sound bassy and lack detail, making it hard to be understood.
- The adaptive noise canceling can sometimes adjust jarringly for no clear reason, even when the 'adaptive' setting is disabled.
- The case can feel a bit bulky in a pocket, and the top might feel weak, raising concerns about durability if dropped.

What Buyers Say
Many users are genuinely surprised by the sound quality and the effectiveness of the active noise cancellation, especially considering the price point. The extensive customization options within the Soundcore app, including HearID and multiple EQ presets, are frequently highlighted as a major advantage. However, a recurring complaint centers around the included ear tips, which many find too flimsy or poorly fitting, impacting both comfort and the effectiveness of the ANC seal. The transparency mode is consistently described as muffled, and call quality in noisy environments is a significant drawback for some.
“Dude, for like 60 bucks, these things sound way better than I expected and the noise canceling actually works on the bus, but seriously, those ear tips are trash, my ears hurt after an hour and I can't find anything else that fits right.”
Common Praise
- Sound quality is clear and detailed, especially after EQ customization.
- Active noise cancellation effectively blocks out low-frequency sounds like engine noise.
- Battery life is exceptionally long, with 10 hours from the buds and 50 hours with the case.
- The Soundcore app offers extensive customization for sound and controls.
- Multi-point connectivity works reliably, allowing seamless switching between devices.
- The price offers significant value for the features provided.
Common Complaints
- Transparency mode sounds muffled and doesn't provide clear environmental awareness.
- Call quality in noisy environments is poor, with the user's voice sounding bassy or unclear.
- The included ear tips are often too thin, don't seal well, or cause discomfort.
- ANC is less effective at canceling out human voices or mid-range frequencies.
- The charging case is somewhat bulky.
- Touch controls, particularly triple-tap, can be finicky or difficult to activate consistently.
Ownership Tips
- The physical button on the case to open the lid is a small detail, but some users find it less convenient than a simple flip-open design.
- Enabling LDAC is not automatic; you have to go into the app to activate it, which takes a few seconds.
- The default EQ is often described as overly bassy or muddy, requiring immediate adjustment in the app for a balanced sound.
- The earbuds are IPX4 rated, and some users have reported them surviving accidental drops into water, suggesting a degree of durability beyond the rating.
- The 'Gaming mode' to lower latency is present but some users find it doesn't significantly improve PC audio lag, leading to noticeable audio/visual desync.
Frequently Asked Questions
Do these earbuds support high-resolution audio?
Yes, they support Hi-Res wireless audio and LDAC technology, which transfers 3× more data than regular Bluetooth for a more detailed sound experience.
How long does the battery last on a single charge?
The earbuds provide 10 hours of playback on a single charge in normal mode, and up to 50 hours total with the charging case. With ANC enabled, you get 8 hours from the buds and 40 hours with the case.
Can I connect these to multiple devices at once?
Yes, the Liberty 4 NC supports multi-point connection with Bluetooth 5.3, allowing you to connect to two devices simultaneously.
Are they suitable for workouts?
They have an IPX4 rating for splash resistance, making them suitable for light runs or workouts. However, they might not stay securely in place during more intense activities like CrossFit or HIIT due to not sitting deep in the ear.
How effective is the noise cancellation?
The active noise cancellation is effective at reducing up to 98.5% of noise, particularly low-frequency sounds like engine rumbles. It's considered very good for the price, though some users note it's less effective against human voices or specific mid-range frequencies.
Can I customize the sound profile?
Absolutely. The Soundcore app includes HearID 2.0 to create a personalized sound profile, a fully adjustable EQ, and 22 preset EQ options to tailor the audio to your preference.
Buying Guide
When you're looking at wireless earbuds, think about where you'll use them most. If you're on noisy commutes, strong active noise cancellation (ANC) is key to blocking out engine rumbles. For long days, battery life matters a lot, both for the earbuds themselves and how many extra charges the case holds. Don't forget about how they fit; a poor seal means both bad sound and ineffective noise canceling.
Active Noise Cancellation (ANC)
This feature actively listens to your environment and generates opposing sound waves to cancel out unwanted noise. It's like having a quiet bubble around your ears, especially effective for constant, low-frequency sounds like airplane engines or HVAC hums.
Battery Life (Earbuds + Case)
This tells you how long the earbuds will play music on a single charge, plus how many times the charging case can recharge them before needing to be plugged in. More hours mean fewer interruptions and less worry about finding an outlet.
LDAC Technology
LDAC is a high-quality audio coding technology that allows for the transmission of more data over Bluetooth. Think of it like streaming a high-definition video instead of a standard-definition one – you get more detail and richness in your music, assuming your source device also supports it.
Multi-point Connection
This feature lets your earbuds connect to two devices simultaneously, like your phone and your laptop. You can seamlessly switch between listening to music on your phone and taking a video call on your laptop without manually disconnecting and reconnecting.
Alternatives
If these don't quite hit the mark, look for alternatives with better ear tip compatibility for a more secure fit, or those specifically reviewed for superior microphone performance in loud environments.
