The charging dock comes with a 300-mAh battery, which is enough to fully charge the headphones up to three times. With a runtime of 8 hours, the battery of the in-ear headphones also promises to last 3 hours longer when listening to music than the Soundliberty 53. At 60 % volume, we recorded just above 6 hours of listening to music in a realistic scenario. According to the manufacturer, the Bluetooth range has been improved from 10 to 30 meters thanks to a better antenna. Additionally, the headphones are certified to be waterproof according to the standard IPX7 that allows for them to withstand being temporarily submerged in water.

The connection to our Android smartphone, which supports Bluetooth standard 5.0, works without any delays on the first try. The new model once again responds to numerous control commands. For example, various touch commands on the sensor surfaces of the in-ear headphones can be used to control the volume level, music playback and to accept calls. The headphones can be used together or separately for example to make calls, since both of them have their own integrated microphone.
