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.

FEATURES SIDE BY SIDE6 topics

Yes and No describe the listed feature. Missing evidence stays unverified.

SELECTED TOPIC

01 / 06

Open-back design

Open-back earcups are not sealed. Start here if your listening space is quiet; this construction is not a sound-quality rating.

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

Samsung Galaxy Buds3 Pro

What it brings

Replaceable S/M/L ear tips, ANC and ambient listening provide fit and noise-control options.
Manufacturer source
The charging case accepts USB-C or wireless charging; a USB cable is supplied.
Manufacturer source Manufacturer source
Pinch controls manage playback and calls, with swipe controls for volume.
Manufacturer source

What to check

24-bit/96 kHz UHQ audio, 360 Audio and Auto Switch have Samsung-device and software conditions; a Bluetooth connection alone does not establish those features.
Manufacturer source
The IP57 rating applies to the earbuds. The charging case is not water resistant, and wet earbuds must be dried before charging.
Manufacturer source
Samsung’s battery figures are conditional maxima, and ANC-on music ratings are lower than ANC-off ratings. A mains or wireless charger is sold separately.
Manufacturer source Manufacturer source

Sennheiser HD 800 S

What it brings

Its 56 mm ring-radiator driver is rated 10–44,100 Hz (−3 dB) with total harmonic distortion of 0.02% or less at 1 kHz and 1 V rms, in a diffuse-field-equalised open design.
