Previously I had strong DT770 headphones Hd 25
Report Qualit price is excellent.
I would do this no doubt opt.

I am a drummer and the metal band with which I use works with squence, click, low squence, all the guitars go through pod live. So by the singer and the battery no other source of sound scne. Then the cost is capital of Systm. I emphasize that beginners with sound Etymotic is not flattering at all. Nothing to do with the DT770. It was the dcption total. For use against it s'avre the soundproofing is excellent so that even low volume it is possible to send potatoes to save the ear is really a discipline required. Contribution to music I noticed that this type costs less comfortable surgical allowed to play much in place. Other dtail apprciable, the cable is smooth, shiny and not flexible trs.

Note that the ER4 is easily disassemble for easy cleaning are.
