Hallo! Never had a real headphone, just IEM. My background: - Triple fi 10 - Sony XBA3 --> both multi BA-IEM Love the precise, clear and 'fast' sound of both but I want to have bluetoot capability and I want a full size headphone. --> wanted: - neutral sounding - wide soundstage - 'high' resolution, clear sounding with good seperation - bluetoot but with option to use wich cable - noice cancellation NOT needed Price and weight not important. Thank you for your recommendations.
