Huawei is rolling out a new global update for the Watch D2 smartwatch. Software version 6.0.0.12 (C00M06) is bringing several new features to users of the original version of this wearable, so it matches the recently released Watch D2 Blue Edition (curr. €349 at Amazon DE).

The release notes for software version 6.0.0.12, as reported by Huaweiblog.de, state that all Watch D2 users can now get a reminder to take a one-off blood pressure measurement. You will receive the alert at your chosen time, with the company suggesting that it will help users to establish a routine. There is another improvement linked to the heart rate app; here, you can now view heart rate variability (HRV) data, as well as a log of historical workout and recovery heart rate data. There are also said to be optimizations to the user interface.

In the change log, Huawei indicates that there is a new HealthMate watch face. This option provides your latest health metrics, as well as a shortcut to start a new health check to collect new data. On top of this, there are said to be general improvements to system stability. Software version 6.0.0.12 appears to be rolling out to users of the Huawei Watch D2 in phases. When it is available, you will be able to download it via the Huawei Health app.

I’ve been interested in technology for as long as I can remember. From a young age, I have loved gadgets and understanding how things work. Since graduating, I have worked for several technology companies across FinTech, AdTech and Robotics.

Steven Slate Audio has announced the VSX Immersion One planar magnetic open-back headphones for music mastering and production. The headphones are available for pre-order at an MSRP of $899 with shipping starting in December 2025.

When coupled with virtualization software, the headphones can simulate the audio reproduction of music played in professional studios and speaker placement by leveraging binaural psychoacoustic technology.

This allows music producers to accurately master tracks without the need to rent actual studio time, according to the company. The software is also designed to emulate other common playback situations, such cars and smartphones.

The VSX Immersion One utilizes a one micron thick Sendy Audio planar diaphragm measuring 97 x 76 mm (3.8 x 3.0 in.) with a frequency response of 20 Hz to 40 kHz. The aluminum body headphones are highlighted by maple wood earcups. A 2.5 m (8.2 ft.) balanced Y-cable connects the 32 ohm impedance headphones to 3.5 mm (1/8-inch) or 6.35 mm (1/4-inch) audio sources.

Readers who simply want to enjoy high-resolution music playback on planar headphones might consider a pair of Audeze LCD-X available on Amazon.

The Logitech MX Master 4 is a well-designed, ergonomic office mouse with innovative features that can make everyday work much easier for professional users. Its quick setup, long battery life, and high-quality construction make it a durable product.

Minor issues such as the lack of a charging cable and the unfinished software are minor weaknesses, but they hardly detract from the overall picture. With a price tag of around $120, the MX Master 4 is primarily aimed at users who value comfort, precision, and productivity and are willing to invest a little more to achieve this.

A clear recommendation for power users who spend a lot of time at the computer and want to optimize their workflows.

The Logitech MX Master 4 is one of the most sought-after productivity mice on the market and is set to continue the success of its predecessors. It promises maximum ergonomics, precise control, and innovative features such as haptic feedback and the Action Ring, which are designed to significantly optimize workflow. The MX Master 4 is designed especially for professionals who spend long hours working at the computer. We reviewed it.

The Logitech MX Master 4 features high-quality materials: the housing is largely made of recycled plastic, while the thumb wheel and main scroll wheel are crafted from robust aluminum.

The non-slip surface has been significantly improved compared to the previous generation, as Logitech has dispensed with the previously much-criticized rubber coating and now uses a more durable coating that is easier to clean. At around 150 grams, the mouse is comparatively heavy, which increases precision when controlling it, but can be annoying for mobile gamers.

The sensor operates at up to 8,000 DPI and can be used reliably even on glass surfaces. Screws for disassembly and possible repair are easily accessible, and Logitech plans to offer replacement batteries, which supports the sustainable use concept.

Setting up the MX Master 4 is quick and easy. The mouse can be connected either via Bluetooth or the included Logi Bolt USB-C receiver, which provides a stable, secure wireless connection with a range of several meters. Users can pair up to three devices and switch between them effortlessly using a button on the bottom of the mouse.

The basic connection is established within seconds, so the mouse is ready to use immediately. To enjoy the full range of features, we recommend installing the free Logi Options+ software, which can be used to configure the Action Ring in particular. The circular menu on this ring allows quick access to up to eight programmable shortcuts, which make navigating and working in complex applications such as Adobe Photoshop, Zoom, or Office noticeably easier. The software design is currently still in the beta phase, but has already proven to be very reliable during the review.

The Logitech MX Master 4 is compatible with all common operating systems such as Windows, macOS, Linux, Android, iOS, iPadOS, and ChromeOS.

Logitech advertises the MX Master 4 with a battery life of up to 70 days with average use, a claim that may well be realistic in practice if haptic feedback is disabled. But even with intensive use, a month should easily be possible with one battery charge.

Fast charging via USB-C provides up to three hours of additional use after just one minute of charging, which meets professional requirements on stressful workdays. Another positive feature is the ability to continue using the mouse while it is charging, so there are no interruptions in your workflow.

The Logitech mouse is charged via a USB-C port on the front. If the battery does eventually die, it should be replaceable by the user.

As a child I was fascinated by my Commodore 16, and this sparked my enthusiasm for computers. Using my first modem, I surfed the BTX videotext system and later the World Wide Web. I have always been captivated by the latest technologies, and this is especially true for mobile devices such as smartphones and tablets. I’ve been part of the Notebookcheck team since 2013 and have also on occasion written for Notebookinfo.de, and I’m looking forward to testing new innovations for our readers. I like to spend my spare time indulging in photography and barbecues and being with my family.

The Nikon Z f currently retails for $1,996 on Amazon and has been on the market for over two years, but Nikon continues to provide software support for this rather unusual system camera. Specifically, the firmware update to version 3.00 is one of the camera’s biggest updates so far.

The firmware mainly introduces a film grain simulation, which adds clearly visible noise to photos that and is intended to resemble the look of analog images. Photographers can adjust the intensity of the film grain in six levels and its coarseness in three levels. The grain is simulated for each photo, so no two images will have the same grain patterns. This feature is also available in videos.
