THE National Telecommunications Agency (Anatel) approved two of Sony’s most premium headphones: the WF-1000XM4 it’s the WH-1000XM5. As complete as they are, the devices are different in their formats: while one is in-ear, the other is circo-auricular. According to the documentation, in Brazil, the headphones should be sold by Multi (ex-Multilaser), but there is still no date set.
The first of these, the WF-1000XM4, was released in June last year and came to clash with the AirPods Pro and the like. It is a TWS headphone that has a robust design and sound insulation with active noise cancellation.
In it, Sony promises superior audio quality compared to other competitors, because it uses the LDAC codec at a transfer rate of up to 990 Kb/s. The headphones are also compatible with spatial audio technology and DSEE Extreme, which uses artificial intelligence to try to recover information lost when audio is compressed.
All this power, according to the company, can be used for up to eight hours straight with noise cancellation activated. In addition, Sony also promises two guaranteed recharges when the case is fully charged. On the other hand, battery life can jump to 12 hours if isolation is turned off.
Outside Brazil, the WF-1000XM4 has been available since last year and costs US$ 279. Although it has been homologated, the device does not have a specific date for being marketed in Brazilian lands. The good news, however, is that your certification makes this “dream” closer to becoming a reality.
WH-1000XM5 is the most premium of headphones
When we talk about the WH-1000XM5, we’re talking about the most premium in Sony’s portfolio. Launched last May, the headphone has a discreet and elegant design.
The highlight is the active noise cancellation that, according to Sony, is better than in previous versions – the company says it has equipped with a second processor especially for the feature.
On the outside, the movement of the headphones is in the articulation with the strap, which has a more ergonomic shape and is covered with synthetic leather to make the experience more comfortable and to put less pressure on the ears of those who use it.

According to Sony, the WH-1000XM5 offers more natural sound and better bass than previous versions. By leaving the phone for just three minutes in the socket, the company promises three hours of use, as long as the active noise cancellation is not turned on. In normal use, the device can be used for up to 30 hours.
We also have connection to multiple devices via Bluetooth and touch controls on the surfaces of both earphones; the box already includes a carrying case as usual.
In the United States, Sony’s most premium headset is also now available and costs US$399. Like the WF-1000XM4, the most expensive device still doesn’t have a date to officially launch in Brazil, but it’s up to Multi to decide. When will you start selling them?
