I will summarize my impressions and characteristics after using Ear (open) for a week.

1. Design
ultra compact charging case

19mm thick slim design easily fits in your pocket or bag.
It is very convenient to carry around on a daily basis because it is not bulky and can always be kept close to you.

Nothing The transparent design unique to the ear series is used, allowing you to see the technical elements inside and feel the technology. Although it has a futuristic design, it is simple and stands out from other companies’ copycat transparent earphones.

intuitive storage
It features a structure that allows you to smoothly take out the earphones from the case, so you can take them out immediately when you want to use them, and they are also easy to store.
The magnets securely hold the earphones in place when stored, reducing the risk of them getting lost.
Even if you play it at random, you’ll get hooked and it feels good every time you finish it.

2. Sound quality

open sound technology
One of the biggest features of Ear (open) is the open listening experience that comes with open sound technology.
Since you can enjoy music while capturing more environmental sounds than ear (Stick), you can enjoy music while paying attention to your surroundings.
This is especially useful when exercising outdoors, making it easier to notice the sounds of cars running.

sound seal system
Designed to minimize sound leakage, you can enjoy your own music without disturbing those around you.
In fact, I used it on a commuter train for a week, and I didn’t notice any sound leakage.

Custom diaphragm and titanium coating
It has a custom diaphragm and titanium coating that enhances bass depth and treble clarity.
Regarding the sound quality, I didn’t have high expectations as I was told that it did not support high resolution such as LDHC, but I was surprised at how much deeper the sound was than I expected.
In particular, the bass is powerful and the treble is clear, allowing you to enjoy an overall well-balanced sound.

3. Comfort

Lightweight and stable fit
It’s extremely lightweight at 8.1g per ear, so you won’t feel any strain on your ears even when using it for long periods of time.
The well-thought-out three-point balance structure provides a secure fit for your ears and provides a sense of stability even during exercise such as running or walking.
Another point is that the fit is good, so you don’t have to worry about it coming off while you are wearing it.
I usually use Suunto wing when running, but ear open is superior in terms of being lighter and less noticeable.

Please note that if you use glasses or sunglasses, there will be some interference when wearing them.
Also, it is difficult to use it while sleeping (the bulge on the silver part on the back interferes with your ears)

4. Performance

battery duration
Ear (open) can be used for up to 8 hours with the earbuds alone, and 30 hours in total when used with the case.
In actual use, it demonstrated performance close to catalog specifications, and the battery life was sufficient for daily use.
It is very convenient that you don’t have to worry about the battery running out even if you use it all day long, and you don’t need to charge it frequently.

Low latency mode
Equipped with a low-latency mode that is convenient when playing games or watching videos, you will hardly notice any lag between audio and video.
Nothing If you are a Phone user, it will switch automatically when you start the game.

dual connection
You can connect to multiple devices at the same time, and you can smoothly switch between different devices such as smartphones and PCs.
You can use it seamlessly without any delays or connection problems when switching.
This is useful when you want to quickly jump into an online meeting on your PC while listening to music on your smartphone.

6.Other features

Waterproof performance (IP54)
It is dustproof and waterproof, making it especially suitable for sports and outdoor use. Being able to use it safely while running or on rainy days is a great feature for active users.
However, it is IP54, so it is difficult to use it in the shower.

pinch control
The pinch control that allows you to playback and adjust the volume on the earphone itself is responsive and intuitive.
Although it is a touch operation rather than a physical button, it works as intended and is very easy to use.
You can change the touch operation assignment in the nothing X app.

General review
Points that can be suggested
・Unique design that cannot be rivaled by imitators
・So comfortable that you forget to wear it
・Very compact case

Points that caught my attention
・IP rating If possible, I would like to use it in a shower or running water environment.
・No wireless charging function This was a useful feature on the Ear. It’s a shame because it was so nice to be able to complete charging just by putting it in the back of the house after returning home.
・Price: It would be better if it was less than 20,000 yen.

I just received mine 3 days ago. I couldn’t use it. It will not stay on!!

Poor design ? Maybe

It just didnt fit my ears. Today I contacted support ( chat)for a return label To send them back. Instead I got a song and dance about a lengthy procedure!!

Wouldn’t even connect me to a supervisor with authority !!!

Overall a bad customer support experience.

Avoid dealing with this company
