Question 1

Are these ok for big heads?

Accepted Answer

As long as you do not have a head like The Mekon you should be fine.

Question 2

Which is more neutral; these or the 650s?

Accepted Answer

IMHO the HD600 is the more neutral.  I was finding the HD600 cable a bit "stringy", tending to get tangled and bought a replacement for the HD650 which is thicker and more easy to manage. It changed the sound significantly - less neutral with more bass and slightly less "air" and reminded me of the HD650!  Looking at the web it is clear that the drivers in the HD600 and 650 are exactly the same so I imagine the only real difference is the cable.  Needless to say I swapped back to the old stringy HD600 cable and got the neutral sound back.

Question 3

What is the frustration free packaging for these? Normally the hd 600s come in a nice box. Is it the same with these?

Accepted Answer

Well, my HD 600's arrived totally exposed in the original manufacturer box and no additional Amazon box to protect my item. I was under the impression that Amazon would at least use some additional box to protect the item from any transit damage. My purchase was not discrete, and this could have been a gift (no gift option either). The outer presentation sleeve on my box was ruined by sticky labels and Amazon tape. All the scuffs and tiny dents could have been avoided by simply using one of the millions of boxes that Amazon normally use each and every day. For something in this price range, surely it's not too much to expect my item to be packed properly like any other Amazon supplied items. One could purchase a £10 headphone, and it would be double boxed! I just don't see the logic and thinking behind frustration free packaging on such high end items, as it was far from being a frustration free experience for me. Amazon, please take this into consideration for the future.

Question 4

Will these work with a portable music player? e.g. ipod, pono

Accepted Answer

I'm sure the person who asked this question would have been satisfied by now, so I'm writing this for others whom are curious and want a definitive and comprehensive answer.Yup. Certainly works with a portable player, at least has no problem sounding good with my Sony a17 walkman.  I don't even need to bring the volume all the way up for it to sound loud enough - i.e., level 23 out of 30.  I'm quite surprised as i expected it to give just a bit more than a whisper on my player, which, from what I heard, has only 4 ohms of output impedance and so would be badly underpowered for these headphones.  But, it is more than enough.  It does leak sound quite a bit from the open-back though.  It isn't going to sound loud to those around you, but they're still going to hear it.  But hey, in this day and age with people having their faces glued to their mobile whatever,  doing so might make them realise that there is life out there.  That said, it isn't as loud as 'ghetto blasters' in the 80s.  So go ahead, do your thing.Secondly, don't worry about adapters for the plug. The headphones comes with a big plug attached, but you can just give it a tug and pull it off to reveal a smaller plug that will fit into a portable player.
