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.

Impedance

Nominal electrical load, not sound quality or loudness. Output capability and headphone sensitivity matter together; impedance alone cannot decide whether an amplifier is needed.

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 it brings and what to check

Beyerdynamic DT 770 PRO

What it brings

The closed-back design gives about 18 dBA of passive noise attenuation, and its dynamic driver with bass-reflex system is rated 5–35,000 Hz at 80 ohms.
Manufacturer source Manufacturer source Manufacturer source
A 3.5 mm plug with a screw-on 6.35 mm adapter covers both common headphone sockets, and the ear and headband pads can be replaced by the owner.
Manufacturer source Manufacturer source Manufacturer source

What to check

The supplied straight cable is 3 m long.
Manufacturer source Manufacturer source Manufacturer source
It weighs 375 g with the cable and is built for a firm professional fit; beyerdynamic's pages give the headband pressure as about 3.5 N in one place and 3.5–5.5 N in another.
Manufacturer source Manufacturer source Manufacturer source

Sennheiser MOMENTUM 4 Wireless

What it brings

Sennheiser rates the battery at up to 60 hours of Bluetooth playback with ANC switched on, with about 2 hours for a full charge and 5 minutes giving up to 4 hours.
Manufacturer source Manufacturer source
Besides Bluetooth 5.2 with aptX Adaptive and two simultaneous connections, it accepts USB-C audio from a PC or Mac and an analogue cable for flight use.
Manufacturer source

What to check

The analogue input is a 2.5 mm socket, so the supplied cable (or a similar one) is needed; plugging it in turns Bluetooth off.
Manufacturer source
Sennheiser rates the mass at about 293 g for the headphones alone, and its 106 dB sensitivity figure uses a digital full-scale reference, so it cannot be compared with passive headphones' ratings.
