Pros
Pro Effective noise cancelling
The feature works really well in preventing outside noise from intruding into your music listening experience. Also, there are very little to no reports of a feeling of pressure in the ears when the feature is active.
Pro Powerful bass with good detail on the mids and highs
The sound tuning of these headphones is focused on the lower frequencies. The bass is quite powerful with good sub-bass extension. Users who listen to a lot of hip-hop, dance and bass-heavy music will certainly enjoy the oomph that these headphones can give. The mids sound natural and smooth, yet the lower regions of these frequencies can be overwhelmed by the powerful bass. The highs are crisp and clear though, which prevents the sound from getting too muddy.
Pro Comfortable to wear for long periods
Soft foam and leather are used in the interior and exterior of the ear pads respectively which makes them feel really soft and smooth on the head. The same material choices can be found in the headband.
Pro Headphones automatically pause/play when put on/removed
The Smart Pause feature detects if you are removing or putting on your headphones. These gestures will trigger the music to pause or play automatically.
Pro Right ear cup functions as remote
When in wireless mode, you do not need to use buttons in order to control the functions of the headphones. The right ear cup lets you control the headphones through touch gestures. You can swipe left or right for next or previous track, swipe up or down to increase or decrease the volume or tap on the ear cup to pause or play track as well as answer or end calls.
Pro Noise cancelling levels can be adjusted
You can set just how much noise is cancelled by the headphones, from maximum active noise cancelling, to an ambient mode which allows some sound into the headphones. You can also turn the feature off entirely.
Pro Great passive noise isolation
These headphones are quite effective at preventing sound leakage, and also passively block out noise really well. This is achieved by the closed ear cup design along with the effective seal from the leather-surfaced ear pads.
Pro Can fold down for easier travel
You can twist the ear cups and then fold them into the headband for a smaller, more travel friendly size. In this state, it should take up a lot less space inside your bag for less hassle when used on the go.
Pro Companion smartphone app offers extra functionality
Sennheiser offers the CapTune smartphone app which allows users to see the battery level of the headphones, adjust the headphones' EQ, and control other functions.
Pro Carrying case gives headphones extra travel protection
The case is made from a tough fabric material which should protect the headphones from minor bumps and scratches.
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 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 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 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 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.
Cons
Con Gesture tracking can be too sensitive
Simply brushing your finger onto the right ear cup can trigger a command for the headphones. This can be annoying for some people.
Con Noise cancelling can introduce hiss
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.
