After 30 years Headphone Probiererei I finally found my dream. Great sound, outstanding wearing comfort, almost perfect Bluetooth transmission and, in my eyes, wonderful design and excellent workmanship quality justify the price for this precious piece. The sound cable is still a touch better in everyday driving but hardly distinguishable for me by Bluetooth. I would now not be described as sound purists, yet the bar was set very high. The Sony has done it. Very strong buy recommendation in this league.
