Thank you all... This is what I needed to hear.   Yes, I know, I'm in wrong part of forum. I noticed it too late.   I have B&W P5 headphones at home, but I want something circumarual and more bass. And Denon.. I tried them, sound great, but they look like very cheap. Yes, I admit that...

And these Monster is absolute trash because you are hear it? Or because just Monster Beats? I want to hear the experiences of people who use them... I was not interested in hypothesis. I want to hear real experiences.

Hi, could you compare these headphones? Monster Beats Pro/Detox or HD 25 II... I don't care prize or construction (design). I care about only sound quality. Thanks

I bought B&W P5... and I'm very happy. Great sound, great design....

Thank you all for advices and your efforts. I will try both models in the audio store again. So, thanks...

Thank you for your experiences. I tried these Beyerdynamic but I did hear no bass and I love a bass. Unfortunately, but beyer I don't want. And other headphones I don't want try already. I want to select only HD 25 or B&W P5. Already now is choosing very difficult. But I still don't know.

Yes, I tried version HD 25-1-II or HD 25-C-II. It is version with 3m coiled cable. 

  I prefer maybe HD 25, but P5 are also great. I don't know, really. This is a reason why I opened this topic. It is so 51% for Senn and 49% for P5... And I like a bass, but I think a HD 25 has strong bass, same like a P5. It is very difficult making decision, but very pleasant making...

I have been try in the store both. And both of them plays very good. I would like to hear experiences of other people. So, thank you for advice for choosing:-)

Hi, I need advice on choosing headphones. I want these headphones - Sennheiser HD 25 or Bowers&Wilkins P5. I will be use these headphones at home with Macbook + DAC/AMP Audinst HUD-mx1 and at outside with iPhone + Fiio E11.   Please advise, and tell me your experiences...   Thank you...
