Qual è il migliore tra aptX e LDAC?
In 2025, Bluetooth audio codecs have reached a significant advancement, with lossless wireless audio now becoming a reality thanks to modern codecs like aptX Lossless and LE Audio. These codecs enable transmission of CD-quality (lossless) sound over Bluetooth, representing a turning point for audiophiles who want high-resolution audio without wires. However, lossless Bluetooth is still relatively new and supported only on select devices, mainly Android-based, since Apple does not currently support aptX Lossless [2].
Here are key Bluetooth audio codecs relevant in 2025:
-
aptX Lossless: Delivers bit-perfect CD-quality streaming with variable bitrate up to 1000 kbps. Supported on some premium headphones (e.g., Sennheiser Momentum True Wireless 4) and Snapdragon Sound–enabled phones. Provides lossless audio over Bluetooth but limited device support so far [2] [1].
-
LE Audio (LC3 codec): Part of the Bluetooth 5.2 specification and beyond, it enables efficient audio transmission with improved audio quality and lower power consumption. It supports variable bitrates from about 163 to 345 kbps, balancing sound quality and battery life [1] [2].
-
LDAC (Sony): Supports bitrates up to 990 kbps, offering near studio-quality sound. It is widely used in high-end audio devices and works well for Hi-Res audio streaming with some degree of compression [1] [4].
-
aptX Adaptive and aptX HD (Qualcomm): aptX Adaptive varies bitrate up to 420 kbps adapting to connection quality, delivering low latency and high sound quality; aptX HD offers up to 576 kbps bitrate for high-resolution audio [1] [4] [5].
-
SBC: The mandatory baseline codec for Bluetooth audio, with bitrates around 240 to 345 kbps, providing basic stereo sound with notable compression and lower fidelity [1] [3].
Newer codecs like LHDC LL (by Huawei) also offer variable bitrates (400 to 600 kbps), adapting dynamically to connection conditions to optimize sound quality and stability [1].
In summary, by 2025, Bluetooth audio codec technology includes a range of options from the basic SBC to advanced lossless codecs like aptX Lossless and LE Audio’s LC3, facilitating better-than-ever wireless audio quality tailored to device compatibility, power efficiency, and connection conditions [1] [2] [3] [4]. Lossless wireless audio over Bluetooth remains more common on Android devices currently, with gradual adoption in headphones and smartphones.
If you are seeking the best Bluetooth audio quality in 2025, look for devices supporting aptX Lossless, LDAC, or LE Audio codecs on compatible source and receiver devices.
