AKG K81 DJ vs Sony WH-1000XM2

Despite the compact size. the bass is full, has great impact, deep extension yet is not loose. The low end also has a natural quality to it that makes these headphones great for music that is performed using real instruments.
The mids are slightly recessed, but also have a natural tone. The highs are the most recessed or rolled-off, but the detail and airiness of the music is not totally absent. This quality helps give the sound a smooth and pleasing tonality.

The K81 can be used “DJ style”, wherein only one ear cup is in contact with the head. The cups have a smooth swivel action so they can be rotated to face outwards. A user can choose to hold one ear cup up to his or her ear while flipping switches or turning knobs on the mix board with the other hand.

While these are already quite compact, the ear cups can be folded into the headband to reduce their size even further. This makes them easy to stuff inside a bag and travel with.

The clamping force is not too much at all, so acceptable levels of pressure will be applied on the ears. Also, the ear pads are thick with ample pleather padding on the surface. This combination provides adequate cushioning between the ear cups and sides of the head.

The aluminum headband itself has some good flex. Combined with the sliding mechanism of the ear cups, K81 can be adjusted to fit a wide range of head sizes. Also notable are the numbered steps on each side of the headband, which allow for accurate and consistent ear cup positioning.

Although it's mostly made of plastic, the materials don't feel cheap at all. Aside from feeling sturdy, the plastics have a smooth rubber coating which makes them feel premium to the touch. Also, the headband is made out of aluminum which is significantly more durable than an all plastic one.

The bass has good punch and control which works really well with most genres of music. The mids are slightly forward at just the right levels, which ensures that vocals can be clearly heard. The highs are emphasized and sound great with a lot of clarity and detail, especially on the upper registers.

Swiping or tapping on the right ear cup's surface can pause or play track, go to the next track or go back to the previous one and can control volume levels as well. Also, the right ear cup has more of a textured surface compared to the old MDR1000x model's smooth, leather-like surface. This makes gesture control much more accurate on the WH-1000XM2.

If you need to talk while using these, all you need to do is to cover the right ear cup with the palm of your hand. This activates Quick Attention mode which cuts off the music and amplifies voice for easy conversation. To get back to listening to music, all you need to do is to remove the palm from the ear cup.

Aside from just turning noise cancelling on or off, users can set it to Ambient Sound which offers 2 further options.Normal Mode allows some outside noise through, while Voice Mode allows voice frequencies through the noise cancelling.

The WH1000XM2 comes with a companion mobile app that allows you to easily tweak the various settings of the headphones including EQ and noise cancelling levels. The app can also take advantage of the accelerometers in your smartphone as you move, adjusting noise cancelling and audio settings on the fly to give you the optimal listening experience.

These have great noise isolating properties and can block out a good amount of sound even with the noise cancelling off. The ear cups are closed back, while the ear pads go over the ear and seal well, awhich effectively minimizes sound leakage to and from the headphones.

The ear cups can be folded into the headband. This reduces the headphones' size so that it can easily fit inside bags.

The WH-1000XM2's active noise cancelling is one of the best in the market today. With the mode activated, a significant amount of outside noise is blocked, allowing you to really enjoy your music with minimal distractions. The Bose QC 35 II slightly edges out the Sony in this aspect though.

There is a built in microphone which negates the need to remove the headphones to answer a call.

You can use these headphones wired using the detachable 3.5mm cable or you can go wireless with Bluetooth.

The internal battery can last up to 30 hours of listening to music in wireless mode with noise cancelling on. This number goes up to 40 hours in wired mode with noise cancelling activated.

This comes with a carrying case that is made from high quality materials. It should provide extra protection to the headphones against scratches and minor impacts, which are quite common when taking these while traveling.
