🎧 Real Impact on Audio Quality: Myth or Reality?
Bluetooth does NOT directly affect audio quality
Common misconception : "Bluetooth 5.4 = better sound than 5.3"
Reality : Audio quality depends primarily on audio codecs (SBC, AAC, aptX, LDAC, LHDC) and drivers/transducers , not on the Bluetooth version.
What Bluetooth 5.4 REALLY improves:
- Connection stability : Fewer micro-interruptions = smooth experience
- Reduced latency : Perfect audio-video synchronization
- Extended range : Freedom of movement without signal loss
- Energy efficiency : More listening hours
Conclusion : Bluetooth 5.4 does not improve "raw sound quality", but it guarantees a superior listening experience thanks to its stability and responsiveness.
