After about a week in the daily operation, I'm thrilled! Quality, finish and accessories described here several times, just good! Delivery by vicious super fast, thank you! Now to the actual the sound: As in the title written with the correct adapters for me sheer madness. Rock, Pop, Soul really all Querbeet tested on IPhone, IPod, IPad and the Technics amplifier my conditioning, hell! Even at very high volume at the plant is still the perfect and very clear sound, no distort, or otherwise. If you like a lot of bass, could be wrong with this policy. The best test yourself. For me an absolute buy recommendation!
