Sony has expanded its 1000X truly wireless headphone range introducing the new WF-1000XM4 with leading noise cancelling capabilities and improved design for added comfort.

The newly designed Integrated Processor V1 combined with Bluetooth System on Chip technology delivers what Sony claims to be the industry’s highest level of noise cancelling while using less power than its predecessor.

Featuring dual noise sensor microphones, the WF-1000XM4 hears and analyses ambient noise for highly accurate noise cancellation, which is further improved by the newly designed 6mm driver unit with a 20% increase in magnet volume.

Sony has undertaken extensive research on ear shapes since introducing the world’s first in-ear headphones in 1982, the MDR-E252. The WF-1000XM4 combine a shape that matches the ear cavity with a new ergonomic surface design for a more stable fit.

The newly developed Noise Isolation Earbud Tips are made from a unique soft and elastic foam material that maximises the surface contact area between the earbud tip and the ear canal to provide an improved fit. Automatic Wind Noise Reduction mode detects a windy environment and automatically suppresses it.

Designed to be lighter and more compact, the WF-1000XM4 are 10% smaller than the previous generation without comprising sound quality or battery life, and the charging case is 40% smaller in size.

Each charge provides a full eight hours of use and further 16 hours from the case. A five-minute charge gives users up to 60 minutes of playback and the Sony Headphones Connect app notifies users when the charging case drops below 30%.

Featuring wireless charging with Qi technology, the headphones and case can be charged using the battery share function of a compatible Qi-enabled smartphone. The WF-1000XM4 offer an IPX4 water resistance rating for splashes and sweat.

Superior sound and adaptive technology for any scenario

The WF-1000XM4 support High-Resolution Audio Wireless thanks to Sony’s industry-adopted audio coding technology, LDAC, which transmits around three times more data than conventional Bluetooth audio.

Using Edge-AI, Digital Sound Enhancement Engine (DSEE) Extreme upscales compressed digital music files in real time. It dynamically recognises instrumentation, musical genres and individual elements of each song such as vocals or interludes and restores the high-range sound lost in compression.

First introduced on the Sony WH-1000XM4 overhead headphones, the Speak-to-Chat feature is available on the WF-1000XM4 to automatically pause the music and let in ambient sound as soon as the user speaks to someone. Once the conversation is over, the music will resume. Alternatively, Quick Attention Mode allows users to hear the outside world by placing their finger over the left earbud to instantly decrease the volume.

Adaptive Sound Control senses where the user is and what they are doing – whether on public transport or walking through the park – and the headphones will adjust accordingly to apply the ideal ambient sound settings. This feature can learn to recognise frequently visited places such as the office or the gym and tailor the sound to suit.

Users can simply say ‘Hey Google’ or ‘Alexa’ to activate their preferred voice assistant and enjoy entertainment, connect with friends, listen to music and more hands-free. The headphones also support Google’s new Fast Pair Feature to enable quick Bluetooth pairing with an Android device, locate the headphones and notify users when the battery has been left on and how much charge is remaining. Users can also connect with Windows 10 devices using the Microsoft Swift Pair.

The Sony WF-1000XM4 will be available in Black or Platinum Silver from mid-July 2021 for RRP $449.95 with three Noise Isolation Earbud Tips and USB-C charging cable in the box.
