Bose QuietComfort 35 vs Plantronics BackBeat Fit

Bose's noise cancelling tech is quite effective at blocking ambient noise. This will help you fully enjoy the music with little to virtually no outside noise interfering.

With these, you won't have to deal with long and dangling cables that can be difficult to manage.

The QC35s can play music continuously for up to 20 hours. This should cover most of your trips' duration before needing to recharge.

Bose QC35 connects to 2 devices (for media and phone calls) allowing one to listen to music on the laptop and get calls from the cell phone. Allows to change the music provider (laptop or cell phone) automatically. With Sony or Senheiser all you can do is connect media on one device and phone on the other device... functional but really restricted one you get used with QC35.

The QC 35's ear cups and headband feature quality memory foam material which are soft and supportive so they do not pinch on your ears or apply too much pressure to the top of the head. These contact points are also covered with a quality leather material which feels nice and smooth on the skin.

Despite having internal batteries, these headphones are still fairly lightweight, coming in at 235 grams. This makes the QC35 really easy to wear for extended periods and even while traveling.

You can easily control playlist functions using the buttons on the right ear cup. These functions include volume control as well as the play, pause, next track and previous track commands. The on/off switch for the headphones is also on this ear cup.

Aside from Bluetooth connection, you can also connect the QuietComfort 35 to a source using a 3.5mm cable. This makes the headphones usable even with the battery depleted.

Bass is full and punchy. While the sub-bass is not pronounced, there is good and fast bass extension, and this is what gives the music punch and a sense of tightness.
The mids are full and slightly forward so vocals and guitars can be clearly heard.
The highs are clear and do not distort at high volumes. There is a peak on the upper treble which helps to add more detail and clarity to the music, but some may also find the high frequencies to be quite harsh at times.

Multiple microphones are strategically located on both ear cups, allowing for great voice quality when taking calls. The noise cancelling also helps to clean up the voice quality that goes into the headphones.

Connectivity with source devices is via Bluetooth, so in place of a full headphone cable is a flexible, soft and short cord made of rubber material that keeps the earpieces connected. You won't have to deal with a long and dangling cable.

The highs are not the most detailed, but they are clear and do give an airy feel to the music. The mids are full and forward so vocals will definitely sound great.

Bass is hit or miss though, depending on how well these headphones seal in your ear. If there is a good seal then bass is punchy and tight though not very powerful. Otherwise, it is likely that the bass will sound a bit on the thin side.

The case can be converted into an armband by reversing it inside out. This is very useful as you can use the arm band to store your smartphone while on a run, along with some essentials like your keys or some cash.

The ear tips are made out of a soft and flexible material that is comfortable and supports the weight of the earpieces quite well. This is enhanced by the wing tips that further help to keep the headphones in place.

The design does not create a thorough seal in your ears, which can be a good thing as this will allow you to maintain awareness of what's around you.

The BackBeat Fit can last up to 8 hours of playback from a full charge.

A sweat resistant coating is applied to the interior parts, so splashes of liquid aren't likely to cause damage.

Each of the earpieces have a single button. Different combinations of presses will allow you to pause/play tracks, answer/end calls, adjust volume and do other functions which can be convenient.

The audio from the microphone is not amazing, but it is quite clear with no distortion so it should be good for most conversations.
