Quick Answer: Yes — the POCO X7 Pro supports a wide range of Bluetooth audio codecs, including aptX, LDAC, and LHDC 1.0 to 5.0, along with SBC, AAC, ASHA, LC3, and Auracast. This gives compatible headphones and earbuds access to higher-quality Bluetooth audio. However, the phone does not support aptX Lossless, aptX Adaptive, aptX HD, or MIHC. Xiaomi specifically attributes the lack of aptX Lossless to the MediaTek Dimensity 8400-Ultra platform.
What Bluetooth Audio Codecs Does the POCO X7 Pro Support?
The POCO X7 Pro officially supports the following Bluetooth audio codecs and protocols:
| Codec / Protocol | Purpose |
|---|---|
| SBC, AAC | Standard Bluetooth audio with broad compatibility |
| aptX | Higher-quality Bluetooth audio on compatible devices |
| LDAC | High-resolution Bluetooth audio with higher available bitrates |
| LHDC 1.0–5.0 | High-quality Bluetooth audio with low-latency support |
| ASHA | Audio streaming for compatible hearing aids |
| LC3 | Efficient Bluetooth audio for supported devices |
| Auracast | Broadcast Bluetooth audio to compatible receivers |
Which Bluetooth Codecs Are Missing?
The POCO X7 Pro does not support the following codecs:
- aptX Lossless
- aptX Adaptive
- aptX HD
- MIHC
Xiaomi specifically states that aptX Lossless is not supported because the POCO X7 Pro uses the MediaTek Dimensity 8400-Ultra rather than a Qualcomm Snapdragon chipset.

The available settings can vary between HyperOS versions. If available on your HyperOS version, open Developer options and check Bluetooth Audio Codec while your headphones or earbuds are connected.
- Connect your Bluetooth headphones or earbuds.
- Open Developer options (if not already enabled, this is usually done from
Settings → About phone). - Look for Bluetooth Audio Codec while your headphones are connected.
Important: The codec actually used depends on what is supported by both the POCO X7 Pro and the connected Bluetooth device. Even if the phone supports LDAC, the headphones must also support it for the codec to be selectable.
Which Codec Should You Use?
For the highest-quality Bluetooth audio options supported by the POCO X7 Pro, LDAC or LHDC are the strongest choices, provided your headphones or earbuds also support them.
These codecs can use substantially higher bitrates than basic SBC, although the actual result also depends on the headphones, Bluetooth connection quality, and source audio.
| Codec | Best For |
|---|---|
| SBC | Universal compatibility |
| AAC | Good compatibility and general use |
| aptX | Higher-quality Bluetooth audio on compatible devices |
| LDAC | High-resolution audio (Sony headphones, some earbuds) |
| LHDC | High-quality, low-latency audio (Xiaomi and select brands) |
Final Verdict
The POCO X7 Pro has strong Bluetooth audio capabilities for its class. Its support for aptX, LDAC, and LHDC means that users with compatible headphones or earbuds can access higher-quality wireless audio than basic SBC or AAC alone would allow.
The main limitation is the absence of several advanced codecs, including aptX Lossless, aptX Adaptive, aptX HD, and MIHC. For most users, this will not be a practical issue, as the phone supports LDAC and LHDC for compatible headphones and earbuds. However, if your headphones or earbuds rely on aptX Lossless or aptX Adaptive, the POCO X7 Pro may not be the best match.
