Soundcore Liberty 4 NC wireless earbuds: what should you consider before buying?

If you listen to music every day, take calls on your commute or travel by train, you’re likely to want three things above all: less background noise, a comfortable fit and a battery that won’t run out halfway through the day. On paper, the Soundcore Liberty 4 NC wireless earbuds seem to tick those boxes. Even so, it’s worth comparing product claims with practical specifications before you order.

Common pitfalls when choosing noise-cancelling earbuds

1. A high noise-cancellation percentage doesn’t tell the whole story

A product listing may quote a figure such as 98.5% noise cancellation. According to information from the brand or seller, this kind of figure usually refers to a specific test environment and frequency. Your experience on a train in the UK, on a bike or in a busy office may be different. Low rumbles are often handled differently from voices or sudden noises.

So don’t focus on the percentage alone. Check whether the product has:

  • active noise cancellation, or ANC;
  • a transparency mode that lets you hear your surroundings;
  • a fit that creates a good seal in your ears;
  • adjustable noise cancellation via an app, if that feature is available.

2. “Long battery life” can mean several things

The Soundcore Liberty 4 NC product title states a battery life of up to 50 hours. However, the detailed product description says 10 hours of continuous playback. This difference may mean that the longer battery life includes several recharges from the charging case. Always check whether the stated number of hours applies to a single charge or to the earbuds and charging case together.

For everyday use, these questions matter more than one impressive total:

  • How many hours do the earbuds last on their own?
  • How many extra charges does the case provide?
  • How quickly do they charge via USB Type-C?
  • Is wireless charging actually included, and is it compatible with your charging pad?

3. Bluetooth versions are sometimes presented as sound quality

Bluetooth 5.3 is a current connectivity specification that can help provide a stable connection and use energy efficiently. It doesn’t automatically mean that every audio file will play in high resolution. Your overall experience also depends on the audio codecs, smartphone, streaming service and settings you use.

Key specifications explained

Active noise cancellation and microphones

According to the product information, the Soundcore Liberty 4 NC has adaptive noise cancellation and ambient noise reduction. The earbuds have six microphones. This is relevant for phone calls, as multiple microphones can help pick up your voice and process background noise. The product information doesn’t guarantee that calls will always be completely clear in noisy surroundings, so treat this as a technical indication rather than an absolute promise.

Fit and protection

These are true wireless in-ear earbuds. The fit affects not only comfort, but also how much outside noise is blocked and how effective ANC feels. Use the supplied ear tips in the size that seals your ear well without causing pressure.

The stated rating is IPX4. This means the product is rated as splash-resistant under the specified protection classification. IPX4 doesn’t mean waterproof or suitable for submersion. Wipe the earbuds clean after use, and only charge them once the connectors are dry.

Controls and charging

The Liberty 4 NC has touch controls, a charging case and a USB Type-C cable. The product title also mentions wireless charging. As the detailed description mainly refers to USB Type-C, it’s worth checking the current product page before buying to confirm exactly which charging features are included.
