I own the Blaupunkt now one week and had a direct comparison to my Bose QuietComfort 15. The bass when Blaupunkt are strong, the sound improves extremely when switching the noise reduction that can be regulated. Interestingly, the higher regulated the clearer the sound. Anyway, in my copy. The Noise Reduction works well, simple test, set up without music and then turn on and adjust it. The fit is ok, the comfort as well. The accessory equipment is completely up to the storage option. Construction and equipment are strongly reminiscent of Bose, so even the Einkabelführung on the left which is austauschabr, in the event of cable breakage, important! The sound is good. For this price a recommendation for those who want to spend not good at 250 EUR More for Bose. However, its sound is another world, airy and well-balanced, but also appropriate for the price. He is and remains my favorite, especially at home. Purchasing the Blaupunkt as second handset I have no regrets, it's ok, come with my wife and me alternately in use.
