1more Triple Driver vs Sennheiser PXC 550

There are two balanced armature drivers which handle the production of high frequencies, resulting in highs that are really detailed and have a lot of sparkle and detail to them.
The 2 BA drivers are complemented by a dynamic driver (hence the triple driver designation) which handles the mids and the lower frequencies. Mids are smooth and clear while the bass is powerful yet at the same time is well controlled.

The earpieces' tips are slightly angled and allows for a more comfortable, deeper and more secure fit in the ears.

The headphone cable is covered by a fabric sleeve. Not only does this make the cable look and feel expensive, but this also adds to the cable's durability. This also helps prevent the cable from tangling easily.

The inline remote has a metal casing with three buttons that allow you to control tracks, respond to calls as well as adjust the volume.

The remote is compatible with Android and iOS devices.

These in-ears incorporate a lot of metal in the build, with the earpieces, the in-line remote as well as the 3.5mm plug predominantly made out of metal. This gives the headphones nice heft and a quality feel.

The in-line microphone allows you to take calls without having to disconnect these headphones. Microphone sound is rich and has good clarity.

Along with the headphones, you also get silicone and foam ear tips in multiple sizes, a leather carrying case as well as an airplane adapter. These are functional accessories that definitely add a lot of value to the overall package.

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.
