Apple "AirPods (3rd generation)"

Remove Apple's "AirPods (3rd generation)" as a product that represents the complete wireless earphone industry you can't. At first glance, it seems that there is no functional evolution with an open shape similar to the first generation AirPods, but it plays powerful sound with "adaptive equalization" that adjusts the music according to the user's ear. It also supports the "spatial audio" promoted by Apple with Apple Music and Apple TV+, and powers up the high-quality sound and entertainment experience. The battery performance has also been enhanced with 6 hours of playback on a single charge. I would like to recommend "AirPods (3rd generation)", which has excellent functionality that makes use of the ecosystem of Apple products such as iPhone, iPad, and Mac, as a best buy.
