Audio quality is the main difference between the two versions. The Pi7 S2 supports aptX Adaptive streaming at 24-bit/48kHz from supported devices and services. 9.2mm balanced armature dynamic drivers are combined with Bowers & Wilkins’ digital signal processing technology for better audio quality than the Pi5’s CD-class sound and conventional aptX. The Pi7 S2 has one extra microphone per earphone, making it the preferred choice for phone conversations. While both include active noise cancellation (ANC), the Pi7 S2 features an adaptive configuration that analyses your surroundings and adjusts the audio as required for “the greatest possible, uninterrupted listening experience.”
