Sony MDR 7506 vs Bose QuietComfort 35 II

The bass is just right. It may not have the deep sub-bass extension that bass heads crave for, but what is there is fast, tight and punchy. The mids are clear with a hint of warmth, which make vocals and guitars sound very clear and you can easily hear their sonic nuances .
The reproduction of highs is the part that these headphones really shine. They are crystal clear and highly detailed without adding hiss or harshness to the overall sound. Cymbal crashes and pings, for example, are very close to what you would hear if they were played right in front of you.

Despite being sub $100, the MDR 7506 can compete against headphones up to twice the price. These make for great headphones if you are just starting to get serious about your audio and you want a relatively inexpensive yet quality purchase.

The MDR 7506 is built outstandingly well, with high quality materials and with little to no creaks and unnecessary flex. These headphones have been around since 1991, which has given Sony a lot of time to refine the manufacturing process of these cans.

The yokes are collapsible and fold into the headband, reducing the headphones to a much more compact size. Included with each purchase is a synthetic leather pouch for added protection for the headphones when taking them on the go.

These leak very little sound compared to other over-ear headphones. The rear side of the ear cups is fully closed, which effectively minimizes sound leakage. With these, you can fully enjoy your music without disturbing people beside you.

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.
