Apple has introduced the fourth-generation AirPods wireless headphones. In AirPods 4, the company slightly changed the shape of the headphones to make them even more comfortable. AirPods 4 support personalized spatial audio, while Apple said that there will be more bass, and the sound will, of course, be better than previous AirPods. Both versions received a charging case with USB-C and wireless charging support. The operating time with the case will be 30 hours. The headphones use the Apple H2 chip.
