AKG K81 DJ vs Plantronics BackBeat Pro 2

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.

With the BackBeat Pro 2, you get powerful yet clear sound that is comparable to higher end models but at a noticeably more affordable price. Wireless range and stability is quite good and the noise cancelling, while not the best, can reduce a good amount of external noise.

While the active noise canceling is not the best, it is able to reduce a good amount of noise from your surroundings. Loud engine sounds or high pitched noise may still mix in with your music though.

The BackBeat Pro 2’s mids and treble are not forward, yet sound clear and neutral. You may hear a bit of sharpness in the higher frequencies, but overall you’ll get a pleasant listening experience with great details from your music.

The low-end is quite emphasized, so you’ll get a lot of thump from bass hits. Bass lovers will likely find these headphones to be up their alley.

You won’t need to press a button on the headphones or on your source device to pause the music when you need to remove the BackBeat Pro 2. There are sensors inside the headphones that detect this motion, so the music is automatically paused, and then resumed when you put the headphones back on.

Listen to the environment via a microphone without taking off the headphones.

These headphones have Bluetooth connectivity for wireless convenience, but you can also switch to 3.5mm wired mode if the battery runs out and you cannot charge right away.

You’ll be able to hear audio even if you are around 100 feet away from your source device, provided there is a clear line of sight. Signal quality is also pretty good with minimal music cuts and drops.

These headphones can last up to 24 hours of playback from a full charge, and this with moderate volumes in wireless mode with noise cancelling activated. This is very good battery life, considering other wireless headphones at the price range only have around half the battery life on average.
