Also new in Stiftung Warentest's constantly updated headphone database: 16 current Bluetooth headphones - including in-ears, open-ears and headband models. One in-ear reduces ambient noise perfectly, another fails in this test point. The devices also perform very differently in terms of wearing comfort: many fit well or very well, others fall out of the ear easily...

The JBL Live Flex 3 do a lot of things right, making them the ideal choice for anyone who doesn't fancy traditional in-ears with an attachment. They sit comfortably and firmly in the ear even without them, sound better than expected and their battery life impressed us. Unfortunately, the active noise cancellation can't quite keep up...

JBL's Live Flex 3 are versatile headphones and suitable for people who like to enjoy music at a high sound level. The charging case with a visual colour touchscreen is useful as it allows you to adjust the headphones directly, saving you having to go through the app.
