I have summarized the results about earbuds I got after searching all over the internet. And feedback from friends who have used the earbuds. This is not a data based article rather opinion based.

 
The information about earbuds collected until January 2020. So After 6 months this guide should become obsolete. So if you are seeing this article that late, please ignore this and look for recent articles.

Keep in mind :

• This guide is for everyday consumers not for audiophiles
• This was made with the product available in Japan till January 2020.
• The stats are completely subjective.
• I will not providing any technical information here. Get the basic filtering here, then do the confirmation research on internet.
• This is for people who don’t like information overload yet want close to perfect result with the least amount of time.

The best products are :

iOS user:
For every day consumer, the best choices are from Air-pods line up. This is a pretty common knowledge. Although it’s super expensive. You can’t go wrong with this.

The latest one is Airpods Pro - 30,580円 . This is the best one, but for cheaper options you can also look for earlier models.
I would suggest you to buy with the AppleCare+. So in case your device gets stolen you can get a new one with 3000 yen.

Android users:

I didn’t find the overall comfort and convenient level same as Airpods Pro. But the Sony WF-1000XM3 comes close. Although this earbud has the best sound in the market. So if you care about sound the most, this is your choice.

 
Price is 24,000円 - taken from amazon.jp. It was more expensive around 26,000円 in the official website.

Again the stats are completely subjective.

The next best cheapest option for earbuds are :

So if you don’t have the budget yet still looking for the convenience of an earbud and good enough sound quality. And planning to keep the earbuds for 1~2 years. This is in my opinion the next best things.

Soundcore Liberty 2 Pro

 
Price: 14,380円. The price is taken from Amazon.
Anker Soundcore is a Chinese company which is a better brand than generic Chinese hit or miss products.

 
This has impressive features hardware wise. But I don’t like the design being bulkier so pop out a lot in the ear. But from a features per dollars basis, this is the best.
If only I have liked the design, this would have been without doubt my first choice.
