“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.

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

Beats Solo Buds

What it brings

Up to 18 hours of rated playback per charge from the earbuds alone, under Apple’s disclosed iPhone 15 Pro and 50% volume test conditions.
Manufacturer source
Beats calls the carrying case the smallest, lightest it has ever made: it weighs 22 g, each earbud weighs 5.7 g, and the earbuds can be charged in the case directly from a compatible phone, tablet or laptop over USB-C.
Manufacturer source

What to check

Beats explicitly states no active noise cancellation. Four ear-tip sizes provide fit options and passive isolation; Transparency mode support is unspecified.
Manufacturer source Manufacturer source
The case cannot recharge the earbuds on its own. Charging requires the earbuds seated in the case with the case connected to a USB-C power source; no cable is included.
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.
Manufacturer source Manufacturer source
Both a 6.35 mm unbalanced and a 4.4 mm balanced cable are included, and the ear pads, headband padding and dust covers can be replaced by the owner.

What to check

At 300 ohms, check that your amplifier or audio source can drive the headphones properly. The documented connection uses the supplied analogue audio cables with 6.35 mm and 4.4 mm plugs.
Manufacturer source Manufacturer source
Sennheiser describes the intended use as listening at home with high-quality audio systems. A standard 3.5 mm adapter can be used, but the reviewed sources do not explicitly establish whether one is included.
