Engadget Logo "NURAPHONE" that protects your ears with the Japanese version of the Clean noise Cancellation Function and the custom -made sound

More than 40 years since the mass -produced portable music player Walkman was born.Many people always live with music as the catch phrase "No Music, No Life".

However, at home, I still have a hard time listening to the sound I want to hear on the street where the car comes and goes, on the train with a driving sound, the train with the inside of the car, and the cafe where many people are talking.As a result of continuing to increase the volume, you may experience hearing loss, tinnitus, etc., which are young and cannot hear the treble and low range, or even normal speaking voices.

WHO states that such dangers can be avoided by reducing the volume of less than 40 hours a week and 80db or less.If you keep listening to the sound of 85db or more, the hair cells that turn the sound vibration into an electric signal in your ears will be damaged, broken, and no function.

The perfect way to listen to the sound you want to hear outside and protect your ears from the risk of hearing loss is the sound equipment with noise canceling functions.

In the noise canceling, a passive noise canceling that fits perfectly into the ear hole, so -called earplugs -like cancellation, and the external sound is picked up with a dedicated microphone, and the sound of canceling the waveform is released to make an electronic sound.There is a type of active noise canceling to erase.

"Nuraphone" (Nuraphone), which ended the campaign on December 20, 2021, has both them.Although it is an over -ear type, it has a canal -shaped eartip inside, with double passive noise canceling and active noise canceling, "clean noise cancellation function" that completely blocks the external sound.It is installed.

With this device, it must protect the ears of young people in the future from hearing loss and tinnitus.

After the crowdfunding campaign is over, I have the opportunity to try Nuraphone, which started general sales, so I will review it immediately.

Overview and bundle

Nuraphone is almost the same size as a general headphone.The height is 190mm and the width is 170mm.The diameter of the ear cup is 88mm (each is about the size).The weight is 329g, and you may be wondering that it is a little heavy, but it is actually the impression that it is better to have this weight to enhance the adhesion of the ear chip.

The ear cup is not just for covering the ears and blocking the external sound.The ear chips inserted in the ear hole play a normal melody, and the ear cup speaker plays a low -frequency sound.It is explained that the entire cup can be played in a concert hall to play the way to vibrate.

The continuous playback time in the built -in battery is up to 20 hours.The power button is not installed, it is attached to turn it on, turn off, and switch from sleep to power off.The connection profile with three devices can be saved and you can talk, so you can use it for remote work online meetings.

There are two types of ways to connect nuraphone to the device, which is a sound source.Bluetooth or wired.Bluetooth supports AptX HD.The wired is included with the Nuraphone unique terminal and the USB Type-A or the 35mm headphone jack terminal.In addition, you can purchase cables connected to Lightning, USB Type-C, and Micro USB as an optional item.

A sound optimized for you with a dedicated app!

You can hear a PC, smartphone, and a Bluetooth connection portable music player, and you can hear it with a good sound to connect to Bluetooth without thinking, but connected to a smartphone that installed the dedicated app NURA app because you thought you were deceived.We recommend that you start using it after.

By the way, when it comes to headphones or earphones personalization, it is generally required to launch an app and have something like a hearing test, such as "Pee" or "Boo".In some high -spec earphones, there was also an ultrasound scanning of the unevenness in the ear hole so that it sounded the optimal sound.

In the case of nuraphone, it is close to that, and the mechanical bass and treble are heard from Nuraphone for about 1 minute.Users are just waiting in a quiet environment as possible.Even if you do nothing, your personalization is automatically completed.

After that, check the hearing.Compare NURA's original music while switching by default ("neutral") and "Personalized".

Then, adjust the bass level (reaction level) that the ear cup regenerates and watch the tutorial of the operation method.Assign a command to the touch pot tongue on the left and right to complete.The response level can be changed later, so set it again according to your mood.

The personalized sound is much better than the default (neutral) one.Nuraphone is not LDAC (96kHz / 24bit), but supports AptX HD codecs corresponding to high -resolution sound sources up to 48kHz / 24bit.

As I remember one of the idiots, I thought, "If you play high -resolution sound sources wirelessly, you have to support LDAC."If so, "AptX HD is enough!"Of course, I don't think that's the case with other playback devices.

How is it specifically different?In addition to the sound sources purchased at high resolution, I played the Ultra HD (44.1kHz -192kHz, average bit rate 3730kbps, equivalent to high resolution), etc.

Of course, if you just launch and listen to the music player app, you don't know the difference.You can check the difference by launching the NURA app during music playback and switching between neutral and personalized.

Then, in personalized, each sound sounds clearly, but when you return it to neutral, it sounds a little sloppy.If you have a feeling like a writer who is not a sound expert, you may not notice that if you have never heard of a personalization sound, you will not notice "Oh, good sound!"

There is no need to increase the volume because it has high sound insulation

At the beginning, I wrote that for a personal acoustic equipment, it could cause hearing loss or tinnitus even if you were young.So, does Nuraphone really protect the ears of those who love music from those ear disease?

Of course, if you keep listening to music for more than 10 hours every day, you will not be protected by using nuraphone.

However, the high noise canceling function that shuts down to the sound of the flush toilet, and the clear sound that is personalized will bring a satisfying music experience even in small volume.

For the first time, when I met this device, I was impressed by the overpass, saying, "This must be the savior of the ear!"You should be able to keep it. "
