What are the advantages of Bluetooth earphones?

1. The cable does not get tangled, and there is little worry about disconnection
   The most significant difference between wired earphones and Bluetooth earphones is that Bluetooth earphones do not have cables entangled due to wireless connection. There’s no cable entanglement, so you won’t be bothered or disturbed when you’re playing sports. Also, if you put earphones in your bag, if you push them out on a crowded train and try to take them out, it will be hard to get tangled at the bottom … it will not be difficult. Furthermore, since there is little worry about disconnection, it is recommended for those who are in trouble because they frequently disconnect their earphones.
2. Listen to music even when away from your smartphone
   With Bluetooth earphones, you can enjoy music, for example, while charging your smartphone in the corner of a room, near an electrical outlet, or on your sofa.
   There are other benefits besides music, such as placing a smartphone at the table and talking with friends hands-free while doing housework.
3. When listening to your favorite music, has the earphone cable rubbed against your clothes and made a sound such as “roughness” (= touch noise) that made you feel uncomfortable? Bluetooth earphones do not have to worry about wireless connection. You can enjoy music to your heart’s content.

On the contrary, what are the disadvantages of Bluetooth earphones?

1. Need to charge earphones every day
   The maximum usage time of Bluetooth earphones is generally between 3 hours and 5 hours (some models have 7-8 hours). Unlike wired headsets, you can’t use it if it runs out of power, so you need to charge it every day. Also, communication may become unstable if the charge is low.
2. Sound quality may be lower than wired earphones
   Compared to wired headsets, due to differences incompatible audio compression method (codec), communication speed, communication distance, etc., between the smartphone that sends music and the Bluetooth earphone that plays music, Sound quality may be degraded. That said, the sound quality is almost the same as inexpensive wired earphones, so it is a quality that does not matter to those who are not particular about sound quality. Besides, high-quality LDAC and Bluetooth earphones compatible with apps have also appeared in recent years, so if you are concerned about the deterioration in sound quality, you should select a high-quality sound.
3. Rare sound skips and skips
   Since radio waves are used for communication, there may be cases where the sound is skipped in places where wireless communication flies, such as when connected to multiple devices at the same time, or when traveling at an urban station with many people. Also, a delay may occur when transmitting and receiving sound between the terminal and the earphones; for example, a gap may occur between the game screen and the music. You will need to be especially careful when playing games called sound games.
