THE DIFFERENCES, MADE VISIBLE

Visual facts

Differences first. Select a topic for its graphic, sources and conditions.

How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Choose your must-haves

Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

Sennheiser ACCENTUM Wireless

What it brings

  • Sennheiser rates up to 50 hours of Bluetooth playback with ANC on, about 3 hours for a full charge and up to 5 hours from 10 minutes of charging.
    Manufacturer source Manufacturer source
  • It supports aptX HD alongside AAC and SBC, and keeps two Bluetooth devices connected at once.
    Manufacturer source
  • USB-C doubles as a digital audio input from a Mac, PC or mobile device, charging the headphones while it plays.
    Manufacturer source

What to check

  • The documentation lists no analogue headphone socket or cable, so sources without Bluetooth or USB audio cannot be used directly.
    Manufacturer source
  • The box contains only the headphones, a USB cable and paperwork; no carry case is listed.
    Manufacturer source
  • Its 106 dB sensitivity is quoted against digital full scale and is not comparable with passive headphones' ratings.
    Manufacturer source Manufacturer source

Sennheiser HD 480 PRO

What it brings

  • The closed back is rated for a maximum acoustical attenuation of 35 dB at 5 kHz; Sennheiser says its multiple stages of passive sound shielding maintain audio signal integrity, and it names mixing and on-the-go music production, in the studio and beyond, among the applications.
    Manufacturer source
  • Sensitivity is stated both per volt (107 dB SPL) and per milliwatt (98 dB SPL) at 130 Ω, which helps when matching it to an interface or headphone amplifier.
    Manufacturer source
  • The cable detaches and can be fitted to either ear cup, the velour pads are washable and replaceable, and Sennheiser describes the headphones as fully serviceable.
    Manufacturer source Manufacturer source

What to check

  • The standard 700499 box has only the 3 m coiled cable and a protective carrying bag (PRO headphone bag); 1.8 m and 3 m cables, a balanced cable and the recording pad set are listed as separate accessories, and the travel case comes with the separate PRO Plus article.
    Manufacturer source Manufacturer source
  • There is no microphone, wireless connection or active noise cancellation; noise reduction comes only from the closed passive design.
