One of Sony’s successes in the field of headphones is without a doubt the WH-1000XM3, a muffler headset that was launched about two years ago. Now comes the WH-1000XM4, promising to bring the same things that made them successful only with further improvements.
The new noise-canceling headphones WH-1000XM4 look identical to the previous generation, ie with a solid look and come in the same colors of black and cream, in contrast to the competitor that launched the Bose NC 700 which is completely different from the QC35. The main difference is in the improvement in noise filtering as well as the ability to connect them to two devices simultaneously using Bluetooth connectivity.
In fact, there are not many changes inside either as Sony has used the same Q1N processing chip that provides the noise filtering capability, however what has changed is a new Bluetooth chip that processes the music and ambient noise better and faster. Thus, according to Sony, there is an improvement in filtering, especially in the mid range frequency.
The WH-1000XM4 headphones offer the same drivers in the 40mm header and Sony does not claim to improve the sound quality, however it did note that the DSEE Extreme audio chip incorporates artificial intelligence capable of improving audio quality for compressed sound files in real time. Thanks to a combination of 5 microphones around the headphones that provide a clear and accurate sound, Sony also introduced a new option called “Speak to Chat” that automatically pauses the music when you speak and continues it when you finish.
The XM4’s battery life has been improved to 30 hours of use in listening to music. There is also fast charging and that 10 minutes of charging will provide up to 5 hours of listening. The Multipoint capability makes it possible to connect the headphones to two devices at the same time, so for example it is possible to connect them to the mobile phone and the computer together when it is not necessary to transfer the connection between the two.
The price of the WH-1000XM4 is $ 349.99 and they are already available for pre-sale in the US. In Israel, the current generation sells for around NIS 1,200, so it is likely that these are the amounts that the XM4 will also be sold when it is launched later.
