Bose QuietComfort 35 vs Oppo PM-3

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.

Treble is quite detailed, but lacks a bit of sparkle on the highest frequencies as they are rolled off. The mids are just right, not too forward and not too rich. The bass has good presence and punch, but is not very powerful.

Its closed back design along with the fairly thick, leather-surfaced earpads are very effective at keeping the music in and the ambient noise out. This is very useful in tracking situations, and will also help you focus on the audio even when in a busy, noisy place.

The headband and ear cups have fairly thick padding to ease the pressure on the head. These are covered with leather material so they feel smooth.

A headphone amp is not required in order for these to pump up good volume and sound details, so these can work well off of portable devices. There is a noticeable improvement in sound quality and volume when used with a proper amp though.

A combination of high quality plastics and metal are used for these so there is minimal flex and rattles. The headphone joints and yoke also have smooth movement, which make these feel premium when held.

The cables can easily be detached, with 3.5mm jacks as ear cup connectors. This makes looking for new/replacement cables very easy.

Stock cable has an in-line microphone. Not only is this convenient for taking calls while listening to music, but the mic's sound quality is good, with voices sounding clear, full and with good volume.
