Since I am not an expert, but, if you & I listen to music, I'm looking for a mid-range model (CX-500 would place here) decided. As listeners were there erstma connected and tested the notebook. I was just excited because I only supplied the "50-cent" had previously headphones. But when I've tried all the essays and then I decided for size M, I realized that there was suddenly a lot more to feel at listening.
=> It is definitely worth spending a few minutes with the testing of all sizes spend, because for me it was a huge sound difference between M and S / L Headphones
Whether the handset is now for classical music lovers something I can not say, because what applies to the listener the statement of my predecessor: "These things are quite bassy", but that's for me in my musical taste (hip-hop, R ' n 'B, Crunk or House) a direct hit.
Conclusion:
A price of about 70 (as they are also offered) are perhaps not worth the listener, but the 40 are really good investments.
If you like bass-heavy sound, the listeners love (depending on the MP3 player you can of course still some influence).
Processing and accessories have also surprised me positively (especially if you previously familiar only the enclosed bud)
