Nakamichi CERO wireless bluetooth earbuds review

Audio enthusiasts of a certain age must have heard this sentence: A CD case of a Nakamichi submarine is more than 30,000 CNY, which is not a common enthusiast. One rumor is enough to reflect Nakamichi’s influence in the audio industry.

Today, Nakamichi has 72 years of history, and it has always been one of the three major overlords of civil noise reduction systems. However, this professional player only caught up with the last train of TWS, and finally released his own Nakamichi CERO wireless bluetooth earphones at the beginning of the year.

As a latecomer, the Nakamichi CERO wireless bluetooth earphones will obviously not confront Airpods head-on. It will focus on the 300 RMB gear. At the same time, combined with its own special noise reduction skills, consumers can also find a suitable reduction in this price range. Noisy wireless bluetooth earphones.

Nakamichi CERO unboxing

The Nakamichi CERO wireless bluetooth earphones does not waste costs on the packaging. The simple cardboard shell material is printed on the front of the packaging with product renderings, product names and some functional features, such as support for aptX audio technology.

There are the basic parameters of the product on the back of the package. The more interesting thing is that the official clearly stated that 1.5 hours of charging time = full battery = 16 hours of battery life. It seems that the battery life of the Nakamichi CERO wireless bluetooth earphones will be better.

In terms of accessories, the Nakamichi CERO wireless bluetooth earphones is quite satisfactory. Two multi-language paper manuals, a charging cable and three sizes of eartips can adapt to the ear canal size of different people to the greatest extent, which is also standard in the industry.

My first impression of the Nakamichi CERO wireless bluetooth earphones is that it is “lightweight”, and it belongs to the small players even in the entire TWS ranks. The charging case size is only 4.6*2.5*3.8cm, and the weight is about 30g. Girls can hold it with one hand and there is no pressure, not to worry about putting it in a backpack or pocket. It is basically insensible.

The charging case is designed in pure white as a whole, but the white color here tends to be pearl white, with a shiny silver line. In addition to the white design, there is also a black one; the shape is a square design, but in addition to the flat design on the top and bottom, the sides are rounded arcs, which can enhance the feel.

In terms of material, the charging case and earphones are made of plastic, but the whole body has a subtle matte texture.

In addition to the silver line as a decoration, the charging case has four LED power indicators in the center of the front. You can intuitively see the current power of the charging case when you pick up the body.

The Type-C charging port is located on the back. The charging case has the brand logo printed on the front.

The charging case adopts the classic magnetic design, with its compact size, there is no pressure to open and close with one hand. The opening and closing degree is about 100°, the damping is relatively moderate, there is a crisp sound when closed, and the seam is tight when closed.

The earphone part is in the shape of a “noise reduction bean”, but the earphone design conforms to the ergonomic design at the beginning, and the small fit is not easy to fall off. With eartips of different sizes, it can easily adapt to the contour of the ear, so it is stable and reliable, and it is light. The color matching is consistent with the charging box.

In terms of earphone size, a single earphone is only 1.5*3*3cm and weighs about 5g. You don’t have to worry about the earphone falling due to its own weight when you wear it when running.

In terms of control, the Nakamichi CERO wireless bluetooth earphones is basically concentrated on the front of the touch earphones. Through different operations to achieve different functions, such as long press to force the switch, click to adjust the volume and so on.

Sound quality & noise reduction: passive noise reduction

From the brand level, I am full of expectations for the sound quality of the Nakamichi CERO wireless bluetooth earphones, but when I think about the price, I lowered my expectations. It may also be because I lowered my psychological expectations that I got it in the first audition. A lot of surprises.

In terms of hardware, the Nakamichi CERO wireless bluetooth earphones uses a 7mm bio-fiber diaphragm speaker unit, combined with the tuning of its own audio engineer, to make the treble of the Nakamichi CERO wireless bluetooth earphones clear and crisp, the midrange is stable and the reproduction is high, and the bass is deep and thick. Especially rock music, fully satisfy the “wildness” of young people.

In terms of noise reduction, the Nakamichi CERO true wireless bluetooth earphones also uses CVC dual-mic noise reduction technology to effectively suppress background noise. Especially in the call scene, the dual microphone array is used to capture and reduce the noise in the environment, even on the street full of various noises such as car wind noise, talking, whistling, etc., so that the other party can hear clearly We speak.

Battery life & connection & waterproof: 21 hours battery life

The Qualcomm QCC3020 bluetooth chip used in the Nakamichi CERO true wireless bluetooth earphones has aptx audio decoding technology, which makes the connection between the earphones and the mobile phone more stable, the music playing more smoothly and the power consumption is lower. The official advertised earphones plays for 5 hours at a time, and the charging case can also power it for 16 hours, which adds up to 21 hours. According to the actual experience, the battery life is basically consistent with the official.

In terms of waterproof level, it supports IPX4, can withstand the test of splash and waterproof, and can be used normally in light rain.

Summary:

As a cost-effective product of a big brand, the Nakamichi CERO true wireless bluetooth earphones has not lowered its value because of the price.
