I had bouth a QC25 a year ago, and I don´t know exacly when it starts but the Headfone have been presenting a poor sound quality with NC set to Off, it appear like NC on turned on something like a amplifier and equalizer.
I used to have the NC turnned to On, and what I remember is that the sound quality was basic the same when NC is on OR off.
The poor sound quality means basic a flat sound poor bass, the sound is the same a "generic" headphone, no comparation with my others bose products.
Is that the expected behavior or it may be a problem?
Thanks for posting. I am sorry to hear about that. Could I ask a few questions to try and assist?
Please come back and update us when you can.

1) I tried on my iPhone, Macbook and a Windows notebook and I have the same behavior, with NC off the sound is poor but when I turn it on the sound is great like it used to be before.
2) About the battey, are you talking about that one I need to put on QC25 to power on the NC?
If yes, I'm using a new one, but as I said before the problem happen when I'm not using Noise Canceling.
If no, Is there some internal battery to verify?
What I want to mean with "poor" sound is a flat sound, no good bass, no good medium and no good treble, it apears a "normal" Headset, but when I power on the NC, its appears I put my QC25 on a equalizer and ampliffier.
Is there something that I can try?
Thanks in advanced
