After my old DJ headphones (Beyerdynamic DJX-1) has fallen apart, due to material weakness (plastic shit) I was searching for an adequate replacement. There should be a DJ headphones in solid design (As little plastic as possible) be. About various forums I became aware of the Reloop RHP-20, which said that this model is at the crucial points on aluminum and not to "shit plastic". According Herstelller there is also a frequency range 3-30000 Hertz ..... and what can I say? I am absolutely thrilled! The headset pushes you into the ground !!! Bass and volume without end, after 10 seconds on the ears no longer can feel it and only the (removable!) Your cable limited radius of action! I had nothing better, and I've already had and tested some headphones. Conclusion: for this money! Buy, buy, buy !!!!
