My verdict after 4 weeks is very positive. The SoundMAGIC E11BT offer reliable features that ensure carefree use in everyday life. The Bluetooth connection is stable and transmits the sound cleanly without audible artifacts. The sound offers a pleasant warmth with potent low bass, homogeneous mid-range and a soft and transparent treble. Especially the headset functions are a welcome enrichment thanks to the high-quality microphone.
