Supported Codecs
The Soundcore Liberty 4 NC uses Bluetooth 5.3 and supports three codecs: LDAC, AAC, and SBC. It does not support aptX or aptX HD.
- LDAC: High-resolution codec capable of up to 990kbps bitrate.
- AAC: Apple-preferred codec at around 256kbps.
- SBC: Universal basic codec used as a fallback.
The earbuds automatically choose the best available codec based on your connected device. LDAC delivers the highest audio quality when available.
LDAC Codec
LDAC is the strongest codec supported by the Soundcore Liberty 4 NC. It transmits roughly three times more data than standard SBC, resulting in clearer details and better dynamic range.
This codec works best with Android devices running Android 8.0 or newer that have LDAC support. Music from Tidal, Qobuz, or high-resolution files sounds noticeably better when LDAC is active.
AAC Codec
AAC is the default codec the Soundcore Liberty 4 NC uses when connected to an iPhone or other Apple devices. It provides decent quality and good efficiency for wireless audio.
While not as detailed as LDAC, AAC still delivers clear sound for most everyday listening. It performs reliably across a wide range of Apple products.
SBC Codec
SBC is the basic universal codec included on the Soundcore Liberty 4 NC. It ensures compatibility with almost any Bluetooth device but offers the lowest audio quality of the three.
The Liberty 4 NC only falls back to SBC when neither LDAC nor AAC is available. Most users will rarely hear SBC in normal use.
Real-World Performance
With LDAC enabled on a compatible Android phone, the Soundcore Liberty 4 NC produces clearer highs, tighter bass, and more spacious sound. The difference is especially noticeable with high-quality tracks.
On iPhone the Liberty 4 NC uses AAC and still sounds good for casual listening and podcasts. Enabling LDAC can slightly reduce battery life and Bluetooth range in areas with heavy interference.
How to Enable LDAC
Open the Soundcore app and connect the Liberty 4 NC. Go to the settings or sound mode section and select “Preferred Audio Quality” or enable LDAC mode.
An LDAC icon will appear in the app once it is active. Remember to enable it every time you want high-resolution audio, as it does not stay on by default for battery reasons.

How Do I Check Which Codec the Liberty 4 NC Is Using?
On Android, open the Soundcore app and look for the LDAC icon after enabling it. Some Android developer options also show the active codec in the Bluetooth settings.
On iPhone there is no simple way to check, but the earbuds default to AAC automatically.
