Recently, the opportunity to travel by train or bus has increased.Suddenly, when I look around myself, I realize that many people use "complete wireless earphones" on smartphones.Recently, there are technologies, and some models have realized sound quality comparable to wired earphones (although it is expensive ...).
However, those who are still particular about wired earphones (headphones) are still concerned because they are concerned about "interruption of sound" and "latency (latency)" in places where radio waves are crowded, and that battery charging is over.There are many.The author is also a wired earphone group mainly for the reason for charging.
In this "Funa Hanashi", I would like to talk about what I want to be aware of when using wired earphones with Android terminals and iPads with only USB Type-C terminals.Some people may feel "I'm gonna do it now!"
「Pixel 6」にオーディオ変換アダプターを介してイヤフォンを装着……したのですが、実は既に問題が発生しています。何が起こっているか、分かりますか?There are great following options for using wired earphones on terminals with only USB Type-C terminals.
Android terminals that have only USB Type-C terminals are often attached to audio conversion adapters and earphones connected to USB Type-C terminals as "samples".There is also a terminal that has a "large behavior" that comes with both adapter and earphones.
However, recently, some terminals do not include these for the purpose of "environmental consideration" or "cost reduction".In that case, you have to buy a separate adapter or earphone.
ドコモの「Galaxy Z Flip3 5G SC-54B」は3.5mmオーディオジャックを備えませんが、USB Type-C端子に接続できるオーディオ変換アダプターやイヤフォンマイクは付属しませんThere are two major types of audio conversion adapters that connect to USB Type-C terminals.
The analog connection type converts the analog audio line of the USB Type-C terminal to a normal 3.5mm audio jack.There are many smartphones with early USB Type-C terminals.
On the other hand, the digital connection type has a built -in DAC (digital / analog converter) and ADC (analog / digital converter) in the adapter, and analog converts the digital audio sent from the terminal to the earphones, or transmit it to the earphone.Digital converts the audio and sends it to the terminal.
Some smartphones with relatively new USB Type-C terminals do not have an analog audio line on the terminal.Even if you connect an analog -connected adapter to a model that does not have an analog audio line, there is no sound.
とある家電量販店で買ってきた、オウルテック製のオーディオ変換アダプター。左がアナログ接続タイプ、右がデジタル接続タイプ。パッケージを取り払ってアダプターだけにすると、外観から判別することは非常に困難である「Pixel 6」にアナログ接続タイプのオーディオ変換アダプターをつなぐと「使えない」という旨の通知が出ます。この通知をタップすると、オンラインのヘルプサイトにつながりますI have mentioned the audio conversion adapter so far, but I think some people have the question of "What about USB Type-C earphones?"In fact, USB Type-C earphones also include "analog connection type" and "digital connection type".
However, in the USB standard, the USB Type-C-connected analog connection earphones must not exist, so most of the products on the market are digital connection type (analog voice line is the conversion adapter only.For).
Anyway, when purchasing a USB Type-C-connected audio conversion adapter or earphone, be sure to check if your smartphone is compatible with analog connection, and whether the adapter or earphone you are buying is analog connection or digital connection.will do.
