I've been using for many years the P5 and am really happy with that. A few days ago I have now heard the P7 sample and was completely thrilled. I bought the P7 on the spot. I am every time anew Baff how perfect the sound. Bass, middle, treble just absolutely remarkable. I am not a professional and my judgment is purely subjective perception, but I've tried many headphones and P7 are absolute (for me) reference. Someone writes the sound is Ok, but Ok sorry it is true in any way, it is just absolutely amazing. The P7 really play compared to P5 in another league. I also find the perceived quality at the P7 significantly higher value than the P5. This concerns in particular the cable and the control element on the cable.
I drive a lot by train and use the headset primarily for it. The P5 also started with me to push sometime. The P7 nothing suppressed. Even the slightly higher weight does not bother me. I just need to get used to get my "eavesdropper" in the bowls me now. Since I previously had on-Ears, the Over-Ear variant is somewhat foreign to my "bucket". Due to the over-ear design, the P7 wear logically sideways to slightly more. The narrow and therefore more elegant shape I find something beautiful in the P5, but the times are now On-Ears.
All in all, I regret the purchase for a second and recommend it to everyone, at least once to hear the P7 sample. Disconnect from the P5, I like me anyway not for the time being at least.
