I bought these (at £150) expecting much but was shocked by how far they fell short of even competency. They are very uncomfortable, badly designed and the sound is really nothing special. Whatever I did I couldn't get them to sit flush on my ears so that only the top third of each ear cup would rest properly on my ears, the lower part would stick out away from my ears in a most unnerving fashion - remarkable! - I've never had that happen in a headphone - the effect was actually comical! After struggling with them for a while I finally managed to...

Let me start off by saying that I had the previous version of this headphone - the X1, and I got rid of it because of the excessive bass output that spoiled what would have otherwise been a very good headphone. I was hoping that the X2 would correct the faults of the X1 but all I perceive are very minor improvements in bass definition and slightly improved sound-staging.

Vocals especially had this syrupy sweetness which many enthusiasts will like about the HD650, but for me just masked the natural characteristics of the human voice. I find it difficult to...

I came to this headphone after 10 months with a Philips X1. Although the X1 is a good headphone, towards the end of my time with it, I become increasingly dissatisfied with its sound signature. I stopped listening to music regularly and for a long time I didn't realize that the X1 was to blame! Although every time I used it I would be impressed by its abilities, the sound was ultimately just too bass orientated for me; and also the treble tended towards a glassy tone in some music. So after some research, in steps the K612 Pro. Now this headphone is...
