From the review Sennheiser MM 100 and MM 400 Bluetooth headsets: A family review of a headphone family
This thing is awesome! I could hear the music on my iPod touch® perfectly, nearly blocking out the more annoying people around me when I turned them up loud enough. This headset is very comfortable. It's light and the band is kind of thin and fit just behind my head. The sound quality was great."
