Great sound with long lasting battery which are features I am looking for.

Sound is excellent.

Phone calls sound great and the sound is good for the people I talk with.

My word, what a whole new world o f listening... cord free operation with nine to ten hours of listening with noise cancellation and solid sound

The sound is as good or better than when they are wired

The sound quality for the headphones profile is pretty good, but for conference calls I have to switch to the Headset profile which has lower quality drivers and the sound is really bad

Perfect sound with apt-x codec

The sound is a bit better with regular wires, but these are very close

Sound quality and strength are excellent, in several initial hours of testing, I had no sound fallouts, noise

The only downside (I didn't detract a star) is that the voice prompts telling you the device is on or turning off is really cheap sounding.

But in terms of sound, the wired QC25 is not as warm/smooth sounding compared to the QC35ii, neither was the soundstage as wide (only by a slight margin)
