You don't need cables to connect The Air Kab Max headphones connect to your smartphone, tablet or laptop without wires and thanks to True Wireless Stereo (TWS) technology, you don't need cables to connect to each other. They are also equipped with Hall Switch Technology: after the first pairing, they automatically connect to the device as soon as you open the case. You can listen to music or make phone calls even 10 meters away from the connected device without signal loss: even move around in the gym or yoga. Always charge your headphones and case wirelessly. The headphones have a battery life of 5 hours, ideal for longer use. When discharged, it is no problem to simply put them in the charging case and the battery is 100% retained after 1.5 hours. The case offers 4 full charges and provides you with music and calls all day long. Also, the charging case can be powered wirelessly via a wireless charging station or smartphone with reverse wireless charging. Alternatively, you can connect it to a power source such as a power bank or charger via the included USB-A to USB-C cable. The integrated microphone and dual leader technology The Air Kab Max has a built-in microphone on both headphones. Thanks to Dual Leader technology, they are the right companion for intensive working days when you always need to have a headset in your ear to answer calls. This technology will help you: you can only use one of the headphones while the other is charging in the case. This way, you will always have the other available when one of the two is downloaded. The touch buttons give you full control over music and calls with just one touch on the headset and without touching the smartphone. In this way, you never have to push up or lose focus on the road while driving. Even if you want to end the call, just a simple touch or if you are busy and want to reject the call, two touches are enough. With the touch buttons, you can activate the voice assistant, play/pause a song and switch songs.
