Sennheiser PXC 550 vs Phiaton BT 100 NC

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.

You get a lot of useful features from the BT 100 NC which includes decent noise cancelling, Bluetooth as well splash resistance, which makes these earphones great for casual or active use. Sound reproduction has great clarity as well as full mids and okay bass, and should work well with many music genres.

Bass is not emphasized yet is full and has good punch so the sound does not sound lean. The mids are warm and full, so guitars, vocals and drums sound great. The highs are slightly emphasized, which brings out a lot of detail from the music, but can also make cymbal and “s” sounds quite harsh.

You’ll be able to control the various earphone functions using the buttons and switches on the BT 100 NC’s collar. It houses the earphones’ battery and noise cancelling circuitry along with the buttons for answering and ending calls, play/pause/skip/previous tracks, volume adjust and the noise cancelling switch. Aside from being easy to reach, the collar also takes as much weight off of the earpieces as possible, so they stay inside the ears well.

You’ll get a good amount of wireless listening time off of these earphones. Battery life with noise cancelling and wireless activated is around 8 hours, while you can get 12 hours of noise cancelling when these are used in wired mode.

While not the best, the noise-cancelling is decent and can reduce noise that may mix in with your music. You’ll still be able to hear some low pitched noise like the sound of engines though.

You can bring these earphones on the go without the earpieces flopping all over the place when they are not in use. There is a space in each end of the collar where you can dock the earpieces for easier transport.
