Best Nura Nuraphone Black Friday – The Australian manufacturer Nura, a group of scientists and music lovers, realized an ambitious idea with a Kickstarter project in 2016, which has now become ready for series production. The Nuraphone is a novel headphone concept that is supposed to combine the advantages of in-ear and over-ear designs. In addition, an internal signal processor in combination with measurement microphones ensures sound adaptation based on the patient’s own hearing aid. And since the current free update G2, active noise canceling has even been on the equipment list.
We are pleased to present to you a list of Best Nura Nuraphone Black Friday for you. I hope you will choose the best product.

Even the construction of the Nuraphone is unusual: the headphones use closed ear cups, in which in-ears are hidden, which positioned in the ear canal with three earplugs – the manufacturer calls this “Inova”. The construction works with a built-in lithium-ion battery that is essential for operation. It offers a runtime of 20 hours with a three-hour charge. The standard transmission path runs via the Bluetooth codec aptX HD. But it can also communicate via chargeable adapters via analog connections, Lightning, USB-C, or micro-USB. Even when using the analog cable, the Nuraphone must charge, because its electronics (and conversion) always need electricity.
The processing is high quality, as is the neat transport case with magnetic closure. The lightweight construction is based on a padded, adjustable headband made of aluminum and ear cups made of silicone. In order to ensure an air supply under this “second skin”, there are numerous ventilation slots around the ear cups, which, in interaction with the music, noiselessly lead the outside air in through so-called Teslaventils. The Nuraphone has two external and one internal microphone on each side. In addition, touch-sensitive sensor points for function control are provided on the attachment points of the ear cups.
Adaptation to your own ear
The Nuraphone is not the first headphone that advertises an adaptation of the frequency response to your own ear. But it is the first device that evaluates so-called otoacoustic emissions. The background is astonishing because it is based on the scientific knowledge that the ear itself emits sound waves when listening. These depend on the incoming frequencies and levels, but in no way are they identical. Rather, they are the result of a modulation of the hair cells in the inner ear, which results from incoming frequencies and which in turn cause the eardrum to vibrate.
Otoacoustic emissions are around 80 dB quieter than the incoming signals. They were first documented in the 1970s, although their existence had been predicted. In practice, they are an important measurement factor in hospitals for hearing tests for infants. In the Nuraphone, however, the process works in a much more refined form: In response to a series of test signals, the otoacoustic emissions are collected and evaluated via extremely sensitive microphones in the auditory canal. The personal hearing aid is analyzed here and then linearized. With this approach, Nura addresses the fact that headphones from series production do not take into account: the individuality of the hearing aid.
Due to the special approach, personalization of the headphones is essential. It only takes a few minutes. To do this, download the associated free iOS / Android app on your smartphone and create a user account with the manufacturer. After pairing, you will now be guided through the adjustment in a friendly manner. Instead of simple test tones, the audibility of which is manually communicated to the system, the measurement microphones in the Nuraphone collect the otoacoustic emissions themselves in response to the test tones fed in.
You only need to carry out the measurement in a quiet environment, and the app also provides feedback on the correct exterior and interior seating of the Nuraphone, which is essential for successful measurement. The actual measuring process takes about a minute and consists of a series of test tones. The result is an individual listening curve that is automatically linearized and cannot be changed any further. Up to three of these profiles can save in the app so that you can quickly switch between different listeners. The hearing profile itself is shown in the form of a graphic that shows your own hearing sensitivity at certain frequencies in a pie chart.
From now on the Nuraphone personalized. This mode can switch off, which due to the design with the microphones placed optimally for measurement purposes does not lead to satisfactory results.
Active noise canceling
Active noise canceling and social mode can also be switched. More on that later. The so-called immersion model, on the other hand, is infinitely variable; which also requires a more detailed explanation: in addition to the sounding in-ear drivers; the 40 mm drivers in the Nuraphone work in the ear cups, which do not really act on the eardrum; but for one controllable stimulation of the outer ear; and thus provide an additional sensation of low frequencies on the skin. This perceived bass content can be adjusted according to taste, and ranges from a pleasant slight bass boost for additional pressure feeling to hopelessly exaggerated bass chaos. I usually turned this parameter up to a quarter, depending on the playback volume.
The seat of the headphones takes some getting used to due to the construction but also because of the material. Ultimately, however, there is good wearing comfort, even over long periods. On the warm days of this summer, however, the ventilation was insufficient, so I started to sweat under the ear.
In further practice, the Nuraphone scores with an unusual level of comfort: when you put it on; the handset automatically switches on and reactivates a previously existing pairing; informs you about the battery status, and even starts music playback. In principle, it is even possible to pair with different receivers with fast switching. An automatic shutdown when setting down should save the battery. It often works, but not always. The same applies to fast pairing. Depending on the start order of music playback and the iOS app; there were sometimes interruptions in playback that could only be remedied by switching Bluetooth on and off on the iPhone. The manufacturer should therefore make improvements here.
The sensor technology allows separate functions for single and double click per ear cup, which is defined via the app. Control processes by wiping, however, are not provided. You can program playback functions, answer and end calls; which are done with good voice quality, switch the noise-canceling functions, and also volume control by clicking and double-clicking. However, there is also criticism: every triggering of a function is accompanied by a click that cannot be deactivated. To do this, I accidentally triggered functions when I touched the ear cups. Here, however, one can hope for an open ear from the manufacturers. After all, the Nuraphone is functionally updatable. The manufacturer has impressively demonstrated this with the G2 version,
The passive noise insulation of the headphones inside and outside is already quite effective due to the Inova construction; and often works even better in the middle and high frequencies than is the case with established ANC competitors. The update now supplements an additional active noise canceling; the effect of which has been optimized as usual on low-frequency signals. The insulation can only switch on and effectively reduces external noise in practice. Traffic noises, as well as speech noises in the area, are pushed far into the background; so that the music stands out more clearly. Nevertheless, the Nuraphone in this area does not reach the industry leaders; who achieve even higher attenuation values and sometimes work depending on the situation and with environment-dependent switching.
Practical is the so-called social model, which uses the external microphones to re-fade in environmental noises; which is particularly useful for communication and public transport. Ideally, this operating mode should be set to a touch function. The level of the music sound is slightly reduced and outside noise is let through to the ear.
The sound assessment of the Nuraphone must carry out with the personalization switched on; because this is the only way that the headphones display their true strengths. The sound result depends on the degree of the immersion parameter. So there is no such thing as a completely neutral position. Nevertheless, the sound result is impressive. The Nuraphone particularly impresses with its beautiful transparency and detailed image, which not only beautifully draws instruments and voices; but also the stereo panorama and the spatial image and at the same time allows the elements to play together harmoniously – providing a good mix. The headphones are balanced and, at least at low immersive values, have a fairly neutral frequency response. For some pressure in the bass range, it makes sense; at least away from quiet listening environments, to raise the immersive control slightly.
Speaking of bass: The entire bass range down to the lowest register is present, including dynamics, contour, and traceable tonality.
The mids retain the richness of detail, provide a high level of speech intelligibility and avoid overemphasis. Even at high altitudes, it never sounds hard, but it is fast, open, and airy. An all-around coherent result, with which the headphones justify their price of almost 400 euros outside of technical innovation. I would attest the Nuraphone to be suitable for all genres: the reproduction of classic dynamic orchestral recordings is just as successful as the reproduction of jazz trios; rock or dance titles. Only: The Nuraphone is not a really loud listener.
