Hi. Getting my head phone situation settled. Should have come here and done this long ago. The advice is wonderful and people A-1.
When I travel for work, I use a Practical Devices XM6 and ER4P with APS re-cable with my laptop on the airplane. Nice isolation from ambient noise and (to my stone ears) great sound.
Sometimes, though, I work in a hotel room and would like a pair of fold-able over the ear (not necessarily circumaural) headphones, as I don't need the isolation as much and the ER4P IEMs are not "super comfy" for long periods.
I have read alot of positive comments re: Ultrasone Pro 900: can be folded, great reviews and come in a hard case (perfect for packing), but they are often referred to as "bass beasts" - which concerns me. I listen to about 80% jazz of all genres - from fusion like Weather Report and Pat Methany to 50's West Coast acoustics trios, such as Shelly Mann and Sonny Rollins to vocals including Diane Krall - and everything in between. The remaining 20% is half a mix of rock (Santana, Linkin Park, Zeppelin, CSN, etc.) and half "small" classical - no huge orchestral pieces.
I understand a number of people have re-cabled the 750s and the 900s with Moon Audio Silver Dragon to great success, too.
So, is there a recommended "short list for me based on the above? Are the Pro900s on it? The XM6 is IMHO an outstanding DAC/amp that should be able to drive any headphone.
