When choosing truly wireless earbuds, one of the key considerations is the quality of audio performance, which heavily depends on the support for high-quality codecs. The Technics EAH-AZ80 and Samsung Galaxy Buds Pro are two popular options that offer different features in this regard. Understanding their codec support can help consumers make an informed decision based on their audio preferences and device compatibility.

Codec Support Overview

The Technics EAH-AZ80 and Samsung Galaxy Buds Pro both support a range of audio codecs, but there are notable differences. Codec support influences not only audio quality but also latency and device compatibility. Let’s examine each device’s capabilities in detail.

Technics EAH-AZ80

The Technics EAH-AZ80 supports the following codecs:

  • Bluetooth SBC
  • AAC
  • aptX
  • aptX Adaptive
  • LDAC

LDAC is a high-resolution audio codec developed by Sony, supporting up to 990 kbps transfer rates. The inclusion of aptX Adaptive also allows for improved audio quality and lower latency on compatible devices. This wide codec support makes the EAH-AZ80 suitable for audiophiles seeking high-fidelity sound, especially when paired with devices that support LDAC or aptX Adaptive.

Samsung Galaxy Buds Pro

The Samsung Galaxy Buds Pro support the following codecs:

  • Bluetooth SBC
  • AAC
  • Scalable Codec (Samsung proprietary)

The Scalable Codec is a proprietary codec designed by Samsung that dynamically adjusts its bit rate for optimal stability and quality. While it offers excellent performance within Samsung devices, it does not support LDAC or aptX, which limits high-resolution audio playback on non-Samsung devices. However, within the Samsung ecosystem, it provides a seamless and high-quality listening experience.

Performance Implications

The differences in codec support influence various aspects of audio performance:

  • Audio Quality: LDAC and aptX Adaptive support higher bit rates, resulting in richer, more detailed sound. The EAH-AZ80’s support for these codecs generally offers superior high-resolution audio compared to the Galaxy Buds Pro.
  • Device Compatibility: The EAH-AZ80’s broad codec support makes it suitable for use with a variety of devices, including Android and Windows, that support LDAC and aptX. The Galaxy Buds Pro are optimized for Samsung devices, leveraging the Scalable Codec for a tailored experience.
  • Latency: aptX Adaptive and LDAC typically provide lower latency, beneficial for gaming and video watching. The Galaxy Buds Pro may experience slightly higher latency outside the Samsung ecosystem.

Conclusion

For users prioritizing high-resolution audio and broad device compatibility, the Technics EAH-AZ80 offers a more versatile codec support with LDAC and aptX Adaptive. Meanwhile, Samsung Galaxy Buds Pro excel within the Samsung ecosystem, providing seamless integration and proprietary codec advantages. Ultimately, the choice depends on the user’s device ecosystem and their specific audio quality preferences.
