Hewlett-Packard (HP) features custom-tuned audio systems engineered in active collaboration with Bang & Olufsen across many of its premium consumer and professional laptop lines, including the Spectre, Envy, and select elite workstation series. This strategic partnership involves Bang & Olufsen’s acoustic engineers working alongside HP hardware designers to optimize internal speaker chambers, minimize electrical interference, and custom-tune the digital audio software profiles. While the physical speakers are manufactured by HP's hardware supply chain partners, the distinct acoustic signatures, sound equalization software presets, and branding bear the direct engineering oversight of Bang & Olufsen to enhance laptop multimedia performance.
