I use a Asus Zonar D2X Audio Centre installed into my computer for playing my music collection either through my hi fi system or headphones. My current headphones are corded DJ Sennheiser HD25SP and still working well today.
I am looking to upgrade to a high quality cordless headphone similar to (or better than) the frequency range of this current headset. I believe they can be plugged into a jack plug from the Asus soundcard in the computer,as well as an output in the hi fi system. If so, they must have a high-end possibly Dolby-based sound-reproduction covering a range of around 20 to 40 feet maximum and be reasonably lightweight.
I am not sure what I should be looking for when I go about purchasing them so welcome any personal recommendations, suggestions and manufacturer websites that can help me in the selecting process.
Any help would be gratefully appreciated.
Thank you very much in advance.
