We tested the Nuraphone, the headset that fits your hearing

-

The Nuraphone is an innovative model both for its sound customization system and the design of its headphones. Is it enough to make a difference? How to offer the best possible sound for headphones? The Australian company Nura have tackled this thorny problem and have designed a revolutionary model: the Nuraphone, sold about 400 euros. This helmet is distinguished by its design that combines the circum-auricular and the intra-auricular. The inside of the earpiece has a tip that is placed at the entrance of the ear canal to transmit the sound more directly than with conventional supra or circumauricular models. According to the manufacturer, the tip penetrates less into the duct than the in-ear headphones, which explains the unique size. We would have liked the choice between several sizes and people who do not like the headphones may not like this model either. Another potential problem often related to ear-phones, the restitution of the bass. To avoid this problem, Nura ...

With the multiplication of audio formats, not easy to navigate to make the right choice. 01net.com explains the main ones to make sure you do not go wrong. Be immersed in a match and live the same atmosphere as the stadium? This is certainly what every football lover dreams about in front of his television. If the image participates more and more, including the broadcast of some matches in 4K, the audio is still the poor relation of sports retransmissions. However, we do not buy a TV only to watch football (well, normally). It is therefore good to know what the different formats used for cinema sound mean. Not always easy to cope with the acronyms and logos displayed on the data sheets of the devices or on the pockets of DVDs and Blu-ray discs. These are the latter that will usually give you the most systematic access to multichannel audio formats, with several voices in the front, rear and a subwoofer. Netflix also offers some compatible content, both movies and series. Two...
