The can-style WH-1000XM5 incorporates two processors and eight microphones to reduce noise especially in the mid-high frequency range, with automatic noise cancellation optimisation according to the environment.
Sony says the 30mm driver unit improves sound clarity and bass reproduction, while its carbon fibre composite dome improves high frequency sensitivity for more natural sound quality.
Phone conversations in noisy locations are also assisted by a combination of four beamforming microphones and AI-based noise reduction to isolate the user's voice, including improved wind noise reduction.
High-resolution audio is supported via Sony's LDAC (providing the connected device does too), while DSEE Extreme upscales digital music files in real time.
The WH-1000XM5 is 360 Reality Audio certified for use with streaming music services.
The physical design of the new headphones is about comfort as well as performance. The combination of soft fit synthetic leather and a stepless slider are said to provide all-day comfort.
"All-day" also applies to the battery life: Sony claims 30 hours from a single charge, and the WH-1000XM5 can be connected to a USB Power Delivery source to take on three hours worth of charge in three minutes.
Other functions include support for resuming Spotify playback without touching the phone, warnings when the volume is higher than that recommended by the World Health Organisation, compatibility with Google Assistant and Alexa, and the ability to pair with two devices at the same time, automatically switching when necessary to take incoming calls.
The WH-1000XM5 incorporates recycled plastic materials from automobile parts.
Australian release is scheduled for late June 2022, with a suggested retail price of $649.95.
