Hello everyone
I would like some advice on purchasing a good pair of headphones to use with my digital piano.
Since 2003, I have been using Sennheiser HD590s (Imp. 120 Ohm, frequency response 12-38000 Hz), which I have always been very satisfied with. In the sense that the sound of my Kawai CA1200 is even more beautiful in headphones than through its built-in amplification in the room.
The fact is that, five years after 2003, I had to have (fortunately) the left speaker repaired, but for a few months now the left speaker has been buzzing again. The defect is markedly evident with the mid-low sounds of the piano. I must say that I also use these headphones for listening to music from Hi-Fi, and in this case, when listening to vocal, symphonic, or chamber music, I almost don't notice the defect (though, knowing the defect is there, I "make an effort" and then I manage to hear problems even with Hi-Fi listening. The annoyance is also clearly felt in this case if I listen to piano pieces, but not as terribly as when I use the headphones for my piano).
My idea (banal) is that I ruined the headphones myself by using them with the piano: always on the left speaker because that is where the mid-lows are directed most (due to the stereophonic principle that, sitting at the piano, the bass comes from the left).
Now I would like to replace the headphones. I am attracted to the Sennheiser HD598 (Imp. 50 Ohm, frequency response 12-38500 Hz) which seem equivalent to me if not better, but I fear (I am almost certain) that I will ruin those too in a short time.
I am asking you:
what does the difference in impedance between these two headphones entail?
Perhaps a lower impedance should lead me to hope that they are more "robust" headphones?
[I have never understood for which type of user it is useful to aim for high impedance and for whom it is useful to aim for low impedance!... whoever can, please enlighten me!!!]
Aside from the HD598… Can you recommend some headphones (any brand/model/budget) that are tough when it comes to taking hits from heavy octave strikes ff... but also have a sound performance equivalent to those I have used until yesterday?
Thank you all!
