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.

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 300 PRO

What it brings

Sennheiser rates up to 32 dB of passive ambient-noise attenuation from the closed back and viscoelastic ear pads, for loud environments such as stages and broadcast.
Manufacturer source Manufacturer source
Ear pads, headband padding and the cable are described as field-replaceable by the user.
Manufacturer source Manufacturer source
Impedance (64 Ω), sensitivity (108 ±3 dB SPL at 1 V) and maximum SPL (123 dB) are all published, which helps when matching it to a mixer or headphone amplifier.
Manufacturer source

What to check

Sennheiser rates the contact pressure at approx. 6 N for a secure fit, and at approx. 297 g without the cable, comfort over long sessions is personal.
Manufacturer source Manufacturer source
Check the supplied cable configuration: Sennheiser describes a coiled section near the earpiece, lists a 1.5 m cable in the box and approx. 1.55 m in the technical data. The separately listed straight cable is a replacement option. The transducer diameter is not stated.
Manufacturer source Manufacturer source
The specification sheet lists this HD 300 PRO configuration without ActiveGard. Switchable ActiveGard hearing protection belongs to the separate HD 300 PROtect, article 506898; it is distinct from the unresolved active noise-cancellation claim.
