When AirPods took it to the next level. For the fourth generation, Apple does not do things halfway. In particular, the version that interests us, that with &#8220;active noise cancellation&#8221;. Thanks to the first feature, in addition to the USB-C port (note: cable not included), you can place the case on a Qi-certified stand charger or connect it to the Apple Watch charger. The second feature, in addition to emitting an audio signal to confirm that charging is in progress, plays another audio signal to easily find it using the location app in iOS. It is worth noting that, unlike the AirPods Pro 2, the AirPods 4 with active noise cancellation do not have the U1 chip. But unfortunately, all these advances mask a regression: that of autonomy. Apple announced that they can work without ANC&nbsp;<\/p>\n\n\n\n<p><strong><u><a href=\"https:\/\/www.batteriesfast.co.uk\/headphones-battery\/Apple\" data-type=\"link\" data-id=\"https:\/\/www.batteriesfast.co.uk\/headphones-battery\/Apple\">Apple AirPods 4 hearphones battery<\/a><\/u><\/strong><\/p>\n\n\n\n<p>5 hours, and with noise cancellation activated &#8211; 4 hours. On paper, this is already an hour less than the third generation released three years ago. At that time our laboratory measurements even reached 7 minutes and 09 seconds (1 minute and 57 seconds faster than the AirPods 2 earphones battery), which was very good for the market! There is no such progress here, because our use tests under real conditions have shown that the active noise reduction and<\/p>\n\n\n\n<p>performance lasted about 3 minutes and 45 seconds at 50% volume. For comfortable headphones that you want to wear for a long time, this is not a problem, and above all very frustrating, especially because their noise reduction is essential for the typical continuous noise of means of transport (planes, trains, etc.) and is more effective. Unfortunately, Apple has gone backwards in this regard.
