Full product profile Official image

Exact model & source notes

The HD 599 (article 506831) is an open-back, over-ear wired headphone that Sennheiser describes as topping its 500 series, in an ivory finish with brown headband stitching. It has a 38 mm transducer with Sennheiser's E.A.R. (Ergonomic Acoustic Refinement) design, which Sennheiser says channels the audio signal directly into the ears, a 50 Ω impedance and soft replaceable ear pads, and comes with two cables — 3 m with a 6.3 mm plug and 1.2 m with a 3.5 mm plug. Sennheiser gives its weight as 250 g and explicitly lists active noise cancellation as False.

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

Sennheiser HD 560S

What it brings

The angled (E.A.R.) transducers and open-back cups are designed to place sound in front of the listener, similar to a loudspeaker setup.
Manufacturer source
Sennheiser publishes the 120-ohm impedance, a 110 dB at 1 kHz / 1 V rating and <0.05% distortion at 90 dB SPL, which helps judge whether a phone, computer or amplifier output is sufficient.
Manufacturer source Manufacturer source
The cable is detachable, and every official description pairs a 3.5 mm connection with a 6.3 mm one, so both portable devices and hi-fi headphone sockets are covered.
Manufacturer source Manufacturer source

What to check

Sennheiser says the open-back design provides natural propagation of sound waves, but its page gives no noise-isolation or sound-leakage figure.
Manufacturer source
Sennheiser's sources disagree on whether the supplied cable ends in a 3.5 mm plug with a 6.3 mm adapter or the reverse, and the US store description gives a 3 m cable against 1.8 m elsewhere, so check the listing.
Manufacturer source Manufacturer source Manufacturer source
The supplied connection uses 3.5 mm and 6.3 mm audio connectors; Sennheiser’s sources disagree on the cable length and which connector is the plug or adapter.
Manufacturer source Manufacturer source Manufacturer source Manufacturer source

Sennheiser HD 599

What it brings

Two cables are supplied — 3 m with a 6.3 mm straight plug and 1.2 m with a 3.5 mm straight plug — plus a 6.3 mm to 3.5 mm adapter.
Manufacturer source
Sennheiser publishes both the 50 Ω impedance and a 106 dB SPL at 1 V rating, which helps estimate how much output a source needs to drive it.
Manufacturer source
The large ear cups use soft ear pads that Sennheiser describes as replaceable.
Manufacturer source Manufacturer source

What to check

It is an open-back design, and Sennheiser publishes no ambient-noise attenuation figure for it.
Manufacturer source
Sennheiser does not say whether the 250 g weight includes a cable.
