Airpods 1st generation A1602 model will forever change the way you use headphones. When you take from the loading case, they turn on alone and connect to your iPhone, Apple Watch, iPad or Mac. Just put in the ear that the sound starts playing automatically, and for when you take it. To adjust the volume, change music, make a call or search itineraries, activate the crab with just two touches. Thanks to the W1 chip developed by Apple, Airpods use a motion accelerometer and optical sensors to detect when they are in their ear. The W1 chip knows if you are using one or both headphones, it directs the sound and activates the microphone automatically. And when you are on a connection or using the crab, a second accelerometer active dual microphones with space filtering to neutralize background noise and focus only on your voice. Since chip W1 is efficient and consumes little energy, AirPods offer great autonomy with five hours of music in just one load. They come with their pace thanks to the loading case that provides multiple additional loads for over 24 hours of use. If you have little time to recharge, put the airpods in the case for 15 minutes to have three hours of sound.
