Service life difference, user experience difference, audio signal stability difference.
1, the difference in service life: if the wired headset is well preserved, it can be used for a long time, the service life of the wireless Bluetooth headset depends on the service life of the battery, if the battery cannot be used, the Bluetooth headset cannot be used.
2, the user experience difference: the use of wired headphones in daily life is very poor experience, they must be connected with smart phones in a close distance, headphones and mobile phones can only be connected when carrying. Bluetooth wireless headphones have a good use experience, only in the case of full charge can be used, very convenient, now, in order to avoid the trouble of daily charging, Bluetooth headphones are equipped with a charging case and two ears for use, very convenient.
3, the difference between audio signal stability: wireless headphones can be charged, and there will be insufficient endurance problems, and there is no wire connection, the audio signal is unstable compared with the cable, and the sound quality will be worse than the cable, however, the Bluetooth headset version protocol has been updated, and the sound quality and audio stability have been greatly improved.
Each has its own advantages, but for me, wireless is better, because it is convenient, and the sound quality is not worse than wired headphones.
