## Product: Sony WF-1000XM6 Earbuds
**Brand:** Sony

The [Sony WF-1000XM6](https://shopsavvy.com/products/7420dca1-ef83-2efd-decc-711e457f3c29) doesn't include aptX support because Sony focuses on their proprietary LDAC codec, which actually delivers superior audio quality with nearly 3x the bandwidth.

## Codec Comparison

| Codec | Max Bitrate | Quality Level |
|-------|-------------|---------------|
| **LDAC** | 990 kbps | Near-CD quality |
| aptX HD | 576 kbps | High quality |
| aptX | 384 kbps | Standard quality |
| AAC | 256 kbps | Apple standard |
| SBC | 328 kbps | Universal fallback |

LDAC's higher bandwidth enables wireless audio that approaches wired quality—something aptX simply can't match.

## What the WF-1000XM6 Supports

- **LDAC:** Sony's audiophile-grade codec (up to 990 kbps)
- **AAC:** Standard codec for Apple devices
- **SBC:** Universal Bluetooth fallback
- **LC3:** New LE Audio codec for low latency

## Practical Impact by Device

**Android phones (2018+):** LDAC support is built into Android 8.0 and later. Your phone will automatically use LDAC for the best quality—better than aptX would provide anyway.

**iPhones:** Use AAC regardless of earbuds. iPhones don't support LDAC *or* aptX, so this limitation doesn't affect Apple users.

**Windows PCs:** Mixed support. Some support LDAC, others may be limited to SBC. This is where aptX absence can be noticeable.

## When aptX Absence Might Matter

You may notice the missing codec if you:
- Use older Android devices with aptX but no LDAC support
- Frequently switch between devices with varying codec support
- Use legacy Bluetooth transmitters

## Optimizing Your Connection

In the Sony Sound Connect app, adjust **connection priority**:
- **Sound Quality:** Maximum LDAC bitrate
- **Stable Connection:** Steps down to prevent dropouts
- **Low Latency:** Uses LC3 for gaming

**Bottom line:** For most users with modern devices, LDAC provides better audio quality than aptX would have, making this a non-issue in practice.
