AKG K81 DJ vs Phiaton BT 220 NC

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.

You’ll have minimal issues with headphone wires. While there is a cable connecting the earpieces to the active noise cancelling module, you can eliminate the need for a cable from the module to your source device if the source is Bluetooth capable.

These headphones can block out a decent amount of ambient noise. The active noise cancelling filters out most high and mid frequency noise. To further reduce low frequency noise, you’ll want to switch the eartips to the Comply foam ones.

Should the battery run out, you can still use these headphones in wired mode. There is a micro-USB to 3.5mm cable included so you can connect the ANC module to your source device. You won’t get active noise cancelling in this mode though.

The ANC module doubles as a remote, and gives you a lot of control over phone and music functions. There is a dedicated button for answering calls, a switch to turn ANC on or off, as well as buttons for volume adjustment and play/pause.
