Surprising problems brought by the spread of online conferences
With the spread of the new colon virus infection (COVID-19) since last year, our lives have changed significantly.
In addition to the thoroughness of the new life style, such as avoiding 3 denses in everyday life, wearing masks, and disinfection, the promotion of home work (telework) may have been greatly influenced by business people.
The government is also calling for a reduction in the number of employees by 70 % as a measure to prevent infection, and online meetings, meetings, and business negotiations, which used to be gathered in the company, are now normal.
Along with that, new problems have also surfaced.In the online conference, in addition to the stable communication environment, smooth progress skills such as projection of materials and images will correspond, but listening will be listed as a previous basic issue.
If you can't hear the other person's remarks accurately, the meeting can be hindered, which can lead to serious misunderstandings and misunderstandings.
There are many people who use earphones instead of built -in speakers of PCs, but even if the ease of listening is improved, there are problems unique to home and online conferences.
For example, during the meeting, it is difficult to understand the signs of children and pets.
Therefore, @Dime focuses on the bone conduction type earphones that can listen to the other party's remark clearly and deal with problems specific to home from home.This time, I would like to take up the GEO "Bone conduction wireless headphone GRFD-BCH200B300", which is a hot topic with its function and cospa height.

Why is bone conduction earphones suitable for online conferences?
Before introducing the product, let's prepare for the earphones using bone conduction.
Currently, most of the headphones and earphones sold at stores are dynamic, balanced armature or condenser type.
Although the mechanism that produces sound is different, the sound is delivered to the ear hole, and the vibration trembles the eardrum and reaches the organs called the cochlea in the back of the ear.The rough mechanism of "hearing" is that the sound information is delivered to the brain from this cochlea.

On the other hand, the bone conduction is a method of transmitting the sound from the bone near the temple to vibrate the skull to the cochlea to the brain.The point is "hearing" that does not go through the ears and eardrums.
GEO "Bone conduction wireless headphone GRFD-BCH200B300" is attached.It is hard to shift with an ear hook type.
Let's do a simple experiment here.If you block both ears and make a voice, you should hear your voice, even though you should not hear the sound from your ears.
The reason is that, as mentioned above, my voice shakes the skull, and the vibration is delivered to the brain through the cochlea.The way to listen to the sound by the vibration of such bones is bone conduction.
So why is bone conduction earphones suitable for online conferences?
Since bone conduction sends vibration directly to the hearing organs through bones, it is easy to check the surrounding living and environmental sounds, not the driver of the earphone does not block the ears.Therefore, in addition to dealing with the above -mentioned problems, it can be used with confidence even when jogging and walking outdoors.
In addition, large housing can easily feel pressure on the ears, or can be stressed by the skin with the skin in the canal type, but if it is a bone conduction earphone that does not touch the ears in the first place, the risk should be avoided.It can be said that it is hard to get tired even for long use.
From the above perspective, let's check the GEO "Bone conduction wireless headphone GRFD-BCH200B300".
First of all, it is easy to check the surrounding sounds and conversations because of the bone conduction method that does not block the ears, and it is easy to deal with problems when using earphones.
In addition, I want to remember the characteristics of bone conduction, which is less likely to be affected by the surrounding noise, as it transmits vibration directly to the hearing organs through bones.
Because the ears are not blocked, it is easy to answer calls from others.
The body is IPX4 (waterproofing), so it is also resistant to sweat.It can be said that it is suitable for exercising use during exercise, such as running and gym work, along with the fact that it is an ear -hanging type that is hard to shift.
The body is a sweat -resistant IPX4 (waterproof) specification
The feature of GRFD-BCH200B300 is not only bone conduction.
The basic performance of the earphone is about 7 hours consecutive playback and the continuous waiting time is about 200 hours.In addition, I would like to pay attention to the ultra -lightweight body, which has a Ver.5.0 and a 15mm type for Bluetooth, but has only 33g.
The price of 2980 yen (excluding tax / tax 3278 yen) is realized while having the above functions.Currently, online shopping, the advantage of the GRFD-BCH200B300 is clear from the fact that many of the functional products are around 10,000 yen.
Moreover, if it is a GEO online store, free shipping over 2,000 yen!The GRFD-BCH200B300 introduced this time is also eligible, and it will be more advantageous.
Bone conduction method as "New Normal" of earphones
As we have verified so far, bone conduction earphones have different characteristics from ordinary earphones.It is said that the product has appeared on the market around 2006, but it is now increasing its presence.
As mentioned at the beginning, the penetration of the remote conference, as mentioned at the beginning, is also considered such as muscle training and jogging daily to eliminate "home weight."
The GEO "Bone Conductor Wireless Headphone GRFD-BCH200B300" provides a comfortable usage environment in accordance with these conditions.
When the bone conduction earphones once appeared, I remember that there were many dry reputation about sound quality.This was inevitable because of the structure of bone conduction.However, when I used the GRFD-BCH200B300, the sound image was fixed in the center without blurring, and I was able to experience a well-balanced sound with a clear mid range.
If this mid -range regenerative power, there should be no problem not only for listening to the remote conference but also for music playback during exercise.
On the other hand, if you want to be healed by a violin overtone component, or want to leave it to a rhythm section groove centered on the bass, prepare high -resolution -compatible earphones at home.
Such an earphone two -sword style is suitable for this era.
The GRFD-BCH200B300 is a bone conduction earphone that makes it possible from both functions and prices.
