Sennheiser PXC 550 Headphones — Review




  • A nylon covered carrying case lined with felt on the inside. It's shaped like one of those old CD carrying bags, like the letter D.
  • USB to micro USB charging cable
  • 1/8 inch cable to connect the PXC 550 to a non-bluetooth source

Sound signature

  • Bass: Definitely audible. The bass on these cans is not overwhelming, nor clouding of the other frequences. It is punchy and present, and the standard setting is definitely enough for me. People who enjoy more bass should go to the app and turn on “Thump” boost mode for more upper bass frequencies, or “Rumble” for that punch in the gut low bass hit. More than enough bass for anyone with all these options.
  • Upper bass and low mids: The upper bass is the closest to flat I’ve heard when trying all the bluetooth headphones. It’s there, it does the job, it’s not recessed, nor is it presented upfront. Guitars have a good weight to them, you can definitely tell the notes being played by the bass and discern bass and kick drum perfectly. Male voices are well represented and never sound thin.
  • Midrange: The midrange is definitely a bit heavy on the 3–4 Khz which might not be most people’s preference, but is what gives this the typical Sennheiser sound signature. It is not such a bump that guitars become fizzy though, and it’s not too disconnected from the 1–2 Khz range that would give you an impression of disconnection between the body and snap of a snare or between the low end and mids of a guitar. It does favour female vocals over male vocals, giving them breath and sharpness that other pairs I’ve tested fall short of. Male vocals are well represented, but don’t benefit as much from these headphones’ sound signature.
  • Highs: Here is where the Sennheiser eats the competition alive. The highs are pleasing to the ear and never show any signs of sibilance. Acoustic guitars and cymbals come alive in these headphones like no other I tested. That, coupled with the incredible soundstage they have, makes for a very pleasing sonic experience listening to any music that has lots of detail in the high end. What it also does is show every single flaw in the source material, so all those pesky 128kbps MP3 files and low quality youtube videos are going to sound pretty bad in comparison with good sources.
