Pros
Pro Long listening sessions should not be a problem
From a full charge, these headphones can give you 12 hours of playback when listening to music via Bluetooth along with active noise cancelling on. Playback time can last up to around 15 hours with noise cancelling off.
Pro Good passive noise isolation with active noise cancelling
The over-ear, closed back design allows for good sound isolation, minimizing sound leak while also minimizing the outside noise that can interfere with the music. This is further enhanced by active noise cancellation, which actively blocks out noise frequencies.
Pro Active noise cancelling can be used on its own
You can turn on just active noise cancelling feature without the music, for when you just want to shut out outside noise.
Pro Feature rich for the price
The i9BT has a good combination of features that is difficult to find in its price range. It has a fun sound, a closed back design for good noise isolation and active noise cancelling.
Pro Powerful bass and bright highs
The i9BT has a V-shaped sound signature where the mids take a bit of a back seat in favor of the low and high frequencies. The bass is quite powerful so bass drum hits definitely have a lot of punch and depth. This is balanced out by highs that are very airy, bordering on harsh.
The powerful bass makes the i9BT great for bass heavy music like hip hop and dance. The overall V-shape sound however also makes these headphones a good pick for rock and pop genres.
Pro Feels very soft on the head
Along with the fairly thick and high quality memory foam used on the head band and ear cups, the cushions' surface features real leather. Not only does this combination feel really soft, but is also quite smooth on the skin.
Pro Good portability
The traveling case is small and provides room for spare batteries and other components. This makes it pretty portable, for those that can't or don't want to leave their headphones at work.
Pro Battery is easily replaceable
These headphones use a triple-A battery to power noise canceling. Should it run out of charge, it can easily be replaced.
Pro Active noise canceling is very good
With the feature switched on, you can really zone in on the music. Noise canceling is very effective at blocking out ambient noise, especially the lower frequencies. On a flight for example, engine noise is drastically reduced, as well as most of the sound from the conversations in your vicinity.
Pro Plenty of comfort features
The QC25 feels comfortable even after wearing it for several hours. The pads go over the ear and feel soft, as the ample cushioning is covered with supple and high quality synthetic leather. Aside from the usual headband padding, it also has an inner Alcantara lining that feels really nice on the skin.
Pro Noise canceling levels can be adjusted
You have a number of options as to how you want to use these headphones' active noise canceling feature. You can either have the feature on or off while you are listening to music, or have noise canceling on without audio. This is a nifty feature if you just want to enjoy some peace and quiet when in a noisy place.
Pro Light and easy to wear
These headphones will not tire your head or neck out, even if you wear them for quite some time. These are pretty light at around 196 grams.
Pro Fun sound with boosted highs
Sub-bass is a bit laid back, but the overall low-end production is punchy and with good extension. Mids are clear and forward so vocals, guitars and keys sound good with these. The upper treble is boosted, which results in good detail, but can also give harshness to the sound.
Overall, this is a really fun set of cans to listen to, especially if you just want to have a fun music listening experience.
Cons

Some users hear hiss added to the music with active noise cancelling on. This can be distracting, especially if you are sensitive to these high frequencies.

While low frequency sounds are effectively blocked, high frequency ones can still be heard. Female voices and high pitched noises may still get in the way of your music.
Con No noise canceling auto shut-off
The feature continues to drain battery even if the headphones are not used. Turn this off before storing.
Con Noise canceling is uncomfortable for some users
