Sennheiser PXC 550 vs Parrot Zik 3

The feature works really well in preventing outside noise from intruding into your music listening experience. Also, there are very little to no reports of a feeling of pressure in the ears when the feature is active.

The sound tuning of these headphones is focused on the lower frequencies. The bass is quite powerful with good sub-bass extension. Users who listen to a lot of hip-hop, dance and bass-heavy music will certainly enjoy the oomph that these headphones can give. The mids sound natural and smooth, yet the lower regions of these frequencies can be overwhelmed by the powerful bass. The highs are crisp and clear though, which prevents the sound from getting too muddy.

Soft foam and leather are used in the interior and exterior of the ear pads respectively which makes them feel really soft and smooth on the head. The same material choices can be found in the headband.

The Smart Pause feature detects if you are removing or putting on your headphones. These gestures will trigger the music to pause or play automatically.

When in wireless mode, you do not need to use buttons in order to control the functions of the headphones. The right ear cup lets you control the headphones through touch gestures. You can swipe left or right for next or previous track, swipe up or down to increase or decrease the volume or tap on the ear cup to pause or play track as well as answer or end calls.

You can set just how much noise is cancelled by the headphones, from maximum active noise cancelling, to an ambient mode which allows some sound into the headphones. You can also turn the feature off entirely.

These headphones are quite effective at preventing sound leakage, and also passively block out noise really well. This is achieved by the closed ear cup design along with the effective seal from the leather-surfaced ear pads.

You can twist the ear cups and then fold them into the headband for a smaller, more travel friendly size. In this state, it should take up a lot less space inside your bag for less hassle when used on the go.

Sennheiser offers the CapTune smartphone app which allows users to see the battery level of the headphones, adjust the headphones' EQ, and control other functions.

The case is made from a tough fabric material which should protect the headphones from minor bumps and scratches.

The Zik 3 features a solid build. The headband is made out of metal and can flex a good bit without breaking. Headband adjustment is quite stiff, which ensures that your adjustments stay in place. The ear cup surfaces are covered with leather which makes the headphones look and feel premium.

You can remove the right ear cup cover to gain access to the headphones’ battery. You can replace the battery if the performance is diminishing, or you can bring a spare, charged battery to swap in with the depleted one for longer playback use.

The bass reproduction is full and punchy, yet does not get overpowering. Bass hits sound tight, fast and have fairly good depth. The mids sound natural while the highs are clear, yet a bit rolled-off. This allows the Zik 3 to deliver fairly clear sound without getting harsh.

The punchy bass makes these heapdhones work well with popular modern genres like EDM, hip-hop and the like yet can still work well with pop, jazz, classical and similar music genres.

The noise cancelling is fairly effective. While it does not cancel out all ambient noise, the feature reduces a good chunk of it, so it does not interfere too much with your music.

You can swipe left or right for previous or next track, tap to play or pause as well as answer calls with the headphones on. This can be very convenient, as you do not need to deal with small and difficult to press buttons.

The Parrot Zik 3 features Bluetooth as well as NFC connectivity for wireless use, which is great for modern smartphones or devices. If your music player does not have wireless connectivity, a 3.5mm jack can be used.

When you take the headphones from your head or put it back on, the music can automatically pause or resume. The Zik 3's Presence Sensor detects such motions, negating the need to manually pause/play the music.

From a full charge with all of the audio features on, you can get around 7 hours of listening time. However, if you choose to run these in airplane mode (wired connection with noise cancellation) you can get around 16 to 18 hours of use.
