With the WF-1000XM4, Sony introduces another descendant of the successful 1000X headphone family. According to the press release, it should be distinguished by its sound quality and very good noise canceling.
Sony WF-1000XM4 Features
The new Sony in-ear headphones have been equipped with a more powerful processor and adaptive, active noise canceling. Each earphone is equipped with two microphones, so that the ambient noise from the front and the rear can be recorded and reduced accordingly. A special DSP mode should automatically suppress wind noise to a large extent. In addition, the noise-canceling technology now uses less electricity, according to Sony.
The driver has also been redesigned; the 6 mm units are now equipped with a magnet that is 20 percent larger. This not only contributes to the bass reproduction of music, the noise canceling can also work even more effectively, especially at low frequencies.
The ear tips are made of polyurethane foam. It is soft and elastic and should ensure the largest possible contact area between the ear canal and the in-ear. This is important for good sound insulation and a secure fit.
Thanks to the Sony LDAC codec, the WF-1000XM4 supports high-resolution playback, but even compressed music sounds authentic with it: Thanks to a special technology, instruments should be dynamically recognized and the details lost during compression in the high-frequency range can be reconstructed to a certain extent.
Sony also praises the speak-to-chat function, which recognizes the user’s voice and reacts to it: short conversations are possible without taking the in-ears out of the ears or even having to operate them manually – after the conversation, it sets then automatically turns the music back on.
Sony specifies the battery life with eight hours, the charging case enables two-fold recharging, so that the system runtime is up to 24 hours. Thanks to Qi technology, wireless charging is also possible. The new Sony headphones are available in black and silver.
