With its commitment to Sony MDR-1A and the Sony MDR-1R side by side, but one must look very closely to see differences. Has been revised to the cable input and the ear pads are slightly larger at 1A. Clean the Tragekonfort I found the MDR 1R marginally better. For now, the ear pads of my listeners 1A encircle better.
Sonically, I found the 1R already very good, especially when women's voices. He did not come to my mind but to a Audio-Technica ATH-m50x quite reach. Opposite a Sennheiser Momentum On-Ear I found both models sound better resolution.
Weakness at Sony MDR 1R were in my estimation the deeper bass and even sometimes lacked somehow the last punch in the middle. It is at these points of MDR 1A were improved. If you listen to eg Clueso "It So Much - Live" comes right on some concert feeling, while in photos "fear" of the drum is clearly defined. I would rewrite "warm" the sound of the MDR as 1R, the sound of 1A is much cooler, but also clearer.
Included are the Sony MDR 1A two cables (MP3 player and iPhone / iPad / iPod with remote) and a small bag. For me, the Sony MDR 1A scores across the board, and I think he clearly belongs in the price range up to 200 top box.
