Test of the Bluetooth headphones with ANC KEF Space One Wireless Porsche Design Black Edition

The English company KEF, for Kent Engineering & Foundryfounded in 1961 in Maidstone by Raymond Cookepartners with Porsche’s design studio to offer a black-draped edition of the Space One wireless active noise canceling headphones.

The sober packaging of the Space One Wireless contains:in addition to the headphones, a nice black case with semi-rigid shells, an adapter for air travel, a very short 20 centimeters flat USB cable for charging, a second flat jack cable as well, including a remote control with a simple Play/Pause button, as well as a small soft pouch to store accessories.

During the first grip the weight of the device strikes immediately, with 330 grams on the scales, the Space One weighs 90 grams more than a Bose QC35, and 55 more than the Sony WH-1000XM2, its main competitors in the market. However, the origin of this overweight, apart from the presence of batteries inherent in wireless headphones, comes from the materials used. In reality, the bow, joints and parts holding the hulls are made entirely of thick aluminumwith a matt sanded finish of the most beautiful effect, immediately reassuring the user about the sturdiness and durability of the whole, unlike its rivals where plastic is required.

Only the shells containing the speakers are made of plastic, with a strap made of imitation leather, a material found on the padding of the arch. The controls are grouped on the right with two buttons for volume and track change, a Play/Pause button that activates Siri on an iPhone with a long press, an Off/On/ANC-enabled button with three positions, a mini-input and a USB port for charging.

The button that lets you launch and enable Active Noise Canceling is oddly placed, making the maneuvers less obvious than with the competition. We will find on the top of the hulls, hidden under beautiful pierced metal grilles, the microphones used to pick up outside noises to better suppress them.

Once in place, however, the weight is completely forgotten, for a circumauralthe recess of the ear cups is slightly narrower, and will struggle to fully accommodate the largest ears, causing discomfort and a feeling of having misadjusted the headphones. This point will of course depend on the anatomy of each, and remember that when choosing a device at this price, the in-store test is essential.

The Space One Wireless doesn’t have the very practical multipoint Bluetooth option that allows it to pair with two devices† You will therefore have to settle for a single connection, which is extremely easy to set up and particularly stable. No disconnection was reported during our test. The Space One Wireless manages Bluetooth 4.1 and AptX, but not the HD version, but also absent from our iPhones and our Macs. KEF did not consider it appropriate to offer a dedicated applicationallowing, for example, the choice of operating mode, which could have alleviated the ergonomic problems associated with button placement for this task.

On the autonomy side, the KEF headphones are impressive, with Bluetooth and active noise cancellation activated, the Space One Wireless lasts on average just over 30 hoursbefore giving up, a good ten hours of overtime compared to the Bose QC 35. Autonomy reaches 40 hours by deactivating the ANC, and about 105 hours in a wired connection to the active ANC.

KEF is known to place great importance on the sound quality and the accuracy of the reproduction of its devices. The Space One Wireless will be no exception. With its two 40 millimeter speakers, the sound is defined across the spectrumthe bass is fair and realistic rather than exaggerated, no offense bass loversand KEF will be congratulated for not giving in to the fashion of boom at any cost.

If you want more bass, a simple detour through the equalizer will boost it, and the Space One picks up the excess without batting an eyelid. With its original setting, the KEF is versatile and will be at home regardless of the type of music.† Look for slight bumps in the high frequencies (between 5 and 9 kHz), which make the highs stand out, but without dominating the rest of the spectrum.

The active noise cancellation is quite efficientwhich properly masks the ambient sounds of a room and allows you to focus on one place, without however rivaling the tenors of the genre. However, the sound reproduction will be frankly changedwith an effect of box marked, as if the sound lost definition, and that we were listening to the music moving away from the source. The wired connection has little effect on the sound quality of the Space One Wireless.

As is often the case with Bluetooth headsets, the microphone used to pick up the sound of the voice during phone calls remains usable, but nothing more† The display is average enough for your caller to know immediately that you have switched to hands-free mode. Finally, the latency is largely acceptable and even looks like a good student, allowing you to watch a movie in good conditions, with no lag between picture and sound.

The Space One Wireless Porsche Design Black edition (pfff) is a very pleasant Bluetooth headset, both to look at and to listen to† It has a finish and battery life that stand out from the competition, and a sound reproduction that is capable of pleasant listening, regardless of the music style. If the ANC is of a good level, it is better to use it for a long-distance film, where its great autonomy is an asset, than to enjoy the album of your favorite artist, because the implementation function significantly changes its sound quality . The price remains, high-end too. At 399.95 euros, it is in the upper middle of a category where competition is fierce.
