The Sony WF-1000XM4 True Wireless Stereo (TWS) earphones are set to launch in 2021, and plenty of leaks and disclosures have highlighted what to expect. The Japanese electronics conglomerate’s latest true wireless headphones are expected to be the most premium and feature-rich yet, and a leaked new promotional video reveals the features and specifications expected with the new headphones. Besides active noise cancellation and access to Google Assistant, which were even present on the Sony WF-1000XM3, the Sony WF-1000XM4 will have a redesigned design and new features such as wireless charging and phone conversation, in accordance with the promotion video.

The new video was posted to the Sparrows News YouTube channel, which has previously leaked promotional videos for Sony audio products, including that of the Sony WH-1000XM4 over-ear headphones. The video follows numerous leaks which have already shown the design of the Sony WF-1000XM4 earphones and also revealed some of the features and specifications. It confirms the presence of key features including active noise cancellation, wireless charging and talk-to-talk on the Sony WF-1000XM4.

The Sony WF-1000XM4 is expected to undergo big design changes compared to the Sony WF-1000XM3, which launched for Rs. 19,999 in India in 2020. The new headphones are smaller, but retain the basic features and capabilities, and even add a few new ones. These include wireless charging, a popular feature commonly seen on premium TWS headsets now, as well as a talk-to-talk feature introduced with the Sony WH-1000XM4 at the end of 2020. Speak-to-chat puts the emphasis on music paused and lights up transparency mode on the headset automatically when the user’s voice is heard through the headset.

Other notable points shown in the video include a new integrated Sony V1 processor which replaces the QN1e processor on the WF-1000XM3, adaptive sound controls, IPX4 water resistance and up to 8 hours of battery life on the headphones, with a full claimed battery of 24 hour lifespan with charging case. Sony’s 360 Reality Audio sound format will also be supported on the headphones, according to the video.

The Sony WF-1000XM4 will face stiff competition in the high-end true wireless segment, including the aging but still capable AirPods Pro, the Samsung Galaxy Buds Pro, and the Jabra Elite 85t. Sony could opt for a similar price for the WF-1000XM3 of around Rs. 20,000 in India, in order to compete with Samsung and Jabra which are priced below Rs. 20,000.
