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 EACH CHOICE ASKS OF YOU

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 HD 25

What it brings

At about 140 g without the cable, with a rotatable capsule for single-ear listening, the design suits DJ cueing and camera or location monitoring.
Manufacturer source
The cable is detachable, and Sennheiser publishes cable and ear-pad replacement guides and lists spare parts, so worn parts can be replaced instead of the whole headphone.
Manufacturer source Manufacturer source

What to check

The on-ear (supra-aural) pads rest on the ears rather than around them, and Sennheiser states a contact pressure of about 2.5 N, so fit and comfort over long sessions are personal.
Manufacturer source
Sennheiser advertises passive noise isolation from the closed-back design; the supplied cable uses a 3.5 mm plug with a screw-on 6.3 mm adapter.
