Quick summary:

💡 For 1,990 CZK you get features that typically belong to the 3–4 thousand CZK category.

Why Liberty 4NC are an interesting choice

The Soundcore brand (under Anker) has built a reputation over the past few years as a manufacturer offering a solid price/performance ratio. Liberty 4NC belong to the mid-range of their portfolio, but their features compete with significantly more expensive models. The main draws are adaptive ANC 2.0, support for the Hi-Res audio LDAC codec, and a total battery life of up to 50 hours (10 hours for the earbuds themselves + 40 hours with the case).

In practice, this means you can truly relax from ambient noise on public transport or in the office. And if you have an Android phone supporting LDAC, you will hear a difference compared to the basic SBC codec.

Sound and noise cancellation: what to expect

The headphones feature 11mm dynamic drivers with a frequency range of 20–40,000 Hz. The sound profile is rather bass-heavy, but not excessively so – in the Soundcore app, you can fine-tune the equalizer to your preferences (22 presets or fully manual settings are available). Codec support includes SBC, AAC, and LDAC, so both iPhone and Android users with Hi-Res audio will be satisfied.

According to the manufacturer, Adaptive ANC 2.0 eliminates up to 98.5% of ambient noise. In reality, this means significant suppression of low-frequency hum (bus engine, airplane, air conditioning), while higher frequencies like stop announcements or conversations partially penetrate. However, this is a common characteristic of most ANC headphones in this price category.

Practical aspects: battery life, connectivity, controls

One of the biggest advantages is battery life. The earbuds themselves last up to 10 hours of listening, and with the charging case, you get a total of 50 hours. Additionally, fast charging works – 10 minutes in the case means 4 hours of listening. The case also supports wireless charging, which is a nice bonus in this price category.

Connectivity is provided by Bluetooth 5.3 with Multipoint functionality – you can be simultaneously connected to two devices (typically a phone and a laptop) and seamlessly switch between them. The earbuds have touch controls, which can be customized in the app. IPX4 resistance means they can handle sweat and light rain.

What users say

On Alza, the Liberty 4NC have a rating of 4.6 out of 5 from 110 customers, with 89% of them recommending the product. The return rate is low (2.67%), which is a good sign of reliability. Users most often praise the sound quality, functional ANC, battery life, and the well-developed app with an equalizer and hearing test option.

However, there are also critical voices. Several reviewers mention that the earbuds don’t fit ideally in their ears – they find the silicone tips too shallow, and they tend to slip out during movement. This is a very individual matter depending on the shape of the ear canal. Another common point of criticism is the microphone – it’s sufficient for calls in quiet environments, but the quality decreases in noise or wind. Finally, the charging case is larger than competitors’, which might bother those who carry their earbuds in a tight pocket.

When it doesn’t make sense

Pokud sluchátka kupujete primárně na telefonování v hlučném prostředí, Liberty 4NC nejsou ideální volba – mikrofon je jejich slabší stránkou. Podobně pokud máte specifický tvar uší a v minulosti jste měli problémy s držením špuntů, vyplatí se nejdřív vyzkoušet. A pokud preferujete maximálně kompaktní pouzdro do malé kapsy, mohou vám vadit jeho větší rozměry.

Verdict: who it’s worth it for

Soundcore Liberty 4NC are a very strong choice for those who want quality ANC headphones with Hi-Res audio support and don’t want to pay a premium price. For the current 1,990 CZK, you get features that would have cost double a year ago. If they fit well in your ears and you don’t primarily need them for calls, this is one of the best purchases in the TWS earbuds category under 2,500 CZK.
