What it brings and what to check

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.
Manufacturer source Manufacturer source

Sennheiser ACCENTUM Plus Wireless

What it brings

Sennheiser rates up to 50 hours of Bluetooth playback with ANC on, and 10 minutes of charging for up to 5 hours of music.
Manufacturer source Manufacturer source
It keeps wired options: USB-C audio from a Mac, PC or mobile device, and a 2.5 mm analogue input with a 3.5 mm cable in the box.
Manufacturer source
Sennheiser rates the headphones at about 227 g, a figure both the manual and the UK page agree on.
Manufacturer source Manufacturer source

What to check

A full charge takes about 3.5 hours, and the battery is built in.
Manufacturer source Manufacturer source
Sennheiser's manual and UK page disagree on battery capacity (700 versus 800 mAh) and microphone count (four versus two), so those details are shown with both figures.
