Plantronics BackBeat Fit vs Bose QuietComfort 35 II

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.

Most full-sized, wireless over the ear headphones are quite heavy and bulky. The QC 35 IIs on the other hand are relatively compact and light, yet still deliver great performance, battery life and top notch noise cancelling.

The integration of Google Assistant is also a first in headphones, and gives you a host of smart features like notification reading, quick music searches and call making using voice commands and many more.

Bose's noise cancelling tech is quite effective at blocking ambient noise. This will help you fully enjoy the music by virtually eliminating outside noise.

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.

These headphones are much more convenient to use and functional thanks to the Google Assistant upgrade. Press the long, flat button on the left ear cup to activate the feature, and you’ll be able to make voice commands to search for music, start calls, set reminders, get weather updates and many other features. This addition makes the QC 35 II one of the best travelling headphones you can get today.

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

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.

The QC35 IIs can play music continuously for up to 20 hours. This should cover most of your trips' duration before needing to recharge.

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.

You can simply press a button on the right ear-cup to answer a call. This reduces the hassle of having to remove the headphones to take a call.

Despite having internal batteries, these headphones are still fairly lightweight, coming in at under 300 grams. This makes the headphones really easy to wear for extended periods, even when you are on the go.

The QC 35 II'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.

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