Engadget Logo Entered Japanese version of the bone conduction earphones, but music is fun.Shokz Openrun Pro advance review

"Openrun Pro" of SHOKZ (formerly brand name: AfterShokz) announced at CES in Las Vegas, USA will be sold for 23,880 yen in Japan.Prior to that, at 10:00 on January 10, the pre -discount sales were started at Green Funding.

The discount rate varies depending on the plan, but the conclusion is "very recommended".Because it has evolved greatly, it is quite advantageous for readers who are worried about bone conduction earphones to order at crowdfunding.I had a chance to touch my feet, so let's send a review.

The first bone conduction earphone with fun music

The reason for recommending Openrun Pro is that the sound quality has risen to the level where music can be enjoyed.You can feel the sound that you can listen to as a normal music like magic.If you have experienced bone conduction earphones, you know that the bass is weak and the reproducibility is low, knowing the comfortable wearability without blocking your ears.

SHOKZ's products are the top runners of the industry, so PremiumPitch+ 2 of the 8th generation bone conduction technology.In the previous generation model AEROPEX, the sound quality of the middle range was very good, but even in AEROPEX, both the low frequency and frequency characteristics are not sufficient, but the sound field expression that is the base of music."It was difficult.

However, the 9th -generation bone conduction technology TurboPitch, which is used in Openrun Pro, makes you feel like a music atmosphere and a sign.The more you know the bone conduction earphones, the more surprising you are to improve this sound quality.

On top of that, it is 20%smaller than the previous model Aeropex, and the battery duration has been extended from up to 8 hours to up to 10 hours.Of course, the comfort, which is the characteristic of bone conduction earphones, remains the same.Like conventional SHOKZ products, it has high dust and drip -proof performance and is comfortable while wearing glasses.

Only the expressiveness of the music improved without any effect on the product value.I want to affirm here.Openrun Pro is the first bone conduction earphone that makes music fun.

The reason that the low frequency range can be regenerated even with bone conduction

The basic operating unit (Transdusa) of Turbopitch is actually almost the same as the 8th generation technology.However, the new technology has a structure that covers the transduca in a movable portion close to the edge of a speaker called Corecushion.

Transdusa vibrates to convey the sound to the head, which gives CorecUSHION a movement (a diaphragm).By using this phenomenon to the ear through a waterproof mesh that is double, it makes the sound from the middle and low range to the low range.

It seems easy to write in letters, but I imagine that the signal correction know -how is a huge amount, such as matching the phase difference (the time difference between the low frequency and the sound conveyed by the bone conduction) and adjusting the frequency characteristics.If you look at the characteristics difference with the general bone conduction earphones, you can imagine how much the difference is.

However, if you are used to bone conduction earphones, another question may come here.It is alleged that the sound leak is large.Surprisingly, however, Openrun Pro has no more sound leakage.

The reason is that the sound leakage does not increase even though it is surrounded by a mesh

Needless to say, the sound is air vibration, but normal bone conduction earphones convey the vibration through the skull and make the sound feel.It is desirable that this vibration does not move the air as much as possible (does not leak sound).

SHOKZ's products have a history of decreasing sound leakage over generations.However, with new technology, the sound leak is likely to increase because the bass has been enhanced.Nevertheless, sound leakage has not increased.

The reason is that it is designed to cancel the sound leakage.Looking at the transducer of Openrun Pro, there is a waterproof opening using the same double mesh on the upper, lower, and front of the opening, which faces the entrance to the ear canal.These three openings are designed by calculating the distance, position, and size from the transduca, and the sound leak is reduced by canceling in the opposite phase.

Bone conduction earphones cannot cause sound leaks in principle.In fact, if you have someone nearby in a quiet room in Openrun Pro, you will feel a sound leakage.However, it does not leak.

For example, on a train, it will be masked on the noise of the train.Even if you don't go that far, no one should notice the sound leakage of Openrun Pro in the city.Even in the case of nomad work in a cafe, it is mixed with the sounds of various people around you, and it seems that people around you will hardly feel.

Strictly speaking, the sound leaks, but the scene that is a practical problem is that, for example, a nearby person notices when using it in a library.

I want you to use not only running but also in telework

Openrun Pro, as its name suggests, is definitely a suitable product for running.Even if you sweat, the comfort does not hurt, and it is easy to grasp the surrounding situation because the ears are not blocked.Due to the significant improvement in the sound quality, there is no other product that is not comparable to high -quality earphones, but does not become uncomfortable even if you keep wearing it for a long time.

I don't think you need to get lost, especially if you're a telework and work a lot at home.You can work while enjoying music without paying attention to people around you, such as your family, and can participate in teleworking.

SHOKZ has an online conduction headset with a move microphone called OpenComm, but when compared, the built -in microphone of Openrun Pro has more sound quality and the ability to block the surrounding noise.The microphone is attached in two directions, the direction of the mouth and horizontal direction, and has the function of canceling the surrounding noise.Similar yesterday was in OpenComm, but did it evolve?

In telework, many people care about living sounds because they have to prepare a work environment while spending time with their families.Of course not perfect, Openrun Pro will not make others feel uncomfortable.

For those who want to live and play while wearing music

I wrote that the sound quality was greatly improved, but of course it is not equivalent to a high -quality recent Canal -type wireless earphone or headphone.You can enjoy music, but if you want sound quality purely, you should consider normal earphones and headphones.

But I want Openrun Pro to be a completely different genre from such products.I was surprised by Aeropex and OpenComm using the 8th generation technology, but Openrun Pro is a wonderful product that looks good on the expression "wearing music."

Bone conduction earphones depend on the power consumption of the vibrating transducer, so the driving time is shorter as the volume is up to 10 hours.However, this unit can charge rapid charging up to 60%in 20 minutes from zero remaining amount and 90%in 30 minutes.In this case, you can continue to use it all day by charging a small gap.

People who always want to be with music in their lives, those who do not want to let go of music when they are enjoying sports.I want you to try such a person.

I couldn't imagine that I could feel the signs of performances and the size of the sound field with bone conduction earphones.It is likely to be a product that greatly changes the image of "bone conduction".
