Hi, can the owners of QC 25 please tell me if you need to be playing music in order to enjoy the noise cancellation? I need to use them in my office since it's really noisy with a lot of people talking, but I don't want to listen to the music 24/7 just so that I can have noise cancellation.  ...

Yes you can, I got the E3 cable and it acts as a DAC for my ipod touch 2g and my ipod classic. And I am sure it's working as a DAC because the sound is not better or worse but infact a little different. Max I can say is that I feel it becomes a little warmer, and the highs are not that high...

  Hey,   Thanks for the suggestions, I will need to save up before I can buy the headphones. ( Wish HD 558 did not leak sound, otherwise it was perfect ). I received the E07k today, I used it with my Dell 5520 Laptop and listened to Daft Punk - Random Access Memories Vinyl Rip - FLAC. I must...

hey, thanks for the reco, but the Q701 is $260 which is way over my budget and the sextetts is not available in India. Also, I read that Q701s leak sound, I use my headphones extensively in office, so something which does not leak sound would be great. And I cannot exceed $180. thanks again.

  What he said! Anyway, I got the Andes, will receive it tomorrow. I will test it out with HD 438s, if all is good will continue using it otherwise I will look for a better pair of headphones. Recommendations are welcome. Budget is ~ $120 - $ 180

  haha .. so much hate here .. I was also planning on upgrading HD 558 or Bose AE2 ( mostly 558 ) later .. should benefit these I suppose.

Hey, Really nice review. I have a Sennheiser HD 438, do you think it will benefit with the E07K ? I have been really happy with 438s performance not considering the low bass of this thing, using it since 2 years now, hoping that E07 would make it sound better and give it some more punch.
