I already created a thread before saying that I purchased the MDR7506 headphones from Sony and returned them a week later. The reason was the audio felt dead. There was very little bass, the sound stage was horrible, and the highs felt sharp. All of this made my ears fatigue and I literally could not enjoy my music. I am willing to sacrifice some detail in my music just to make it enjoyable. I am looking for warm bass and a large soundstage, as these are the things that matter a lot to me. As the title says, they have to be closed as I will be taking them on bus rides and on my upcoming 2-way 14 hour long plane trip. I listen to a lot of music genres, rock, trance, techno, house, instrumental, and a lot of songs involving vocals (mostly female). I have heard great things about Grado's, however the open back design is a huge turn off.
My initial choice was the ATH-M50's for their looks, audio quality, and the overall positive response that they get but the recent bump to $160 and them being very neutral is now making me look for other options. My budget is around $140, however I strongly suggest that the headphones will be somewhere between $100-120. I will be driving the headphones off a Sandisk Clip+ and a Tablet PC so they have to be easy to drive. I'm really tempted to see what you guys recommend
