Product information

Description

The Sennheiser HD 599 are full-size, open-back wired headphones that deliver a natural, well-balanced audio profile and wide spatial presentation. Featuring large circumaural ear cups, soft replaceable ear pads and an adjustable headband, the HD 599 combines near‑audiophile sound quality with long-wear comfort and a premium brown-and-ivory finish.

Advantages

Open-back design and high-end Sennheiser transducers provide an expansive, natural soundstage with detailed mid and high frequencies. The large ear cups and soft, replaceable cushions reduce pressure on the ears for extended listening sessions. A sturdy headband with subtle metallic accents and quality stitching offers durable, comfortable wear while maintaining an elegant appearance.

Suitable for

Critical at-home listening and music enjoyment
Music discovery and analytical listening
Long listening sessions where comfort is important

Key specifications

How to use

Connect the headphones to your audio source using the supplied 3.5 mm plug; use the 6.3 mm adapter for devices with a larger jack. Position the ear cups over your ears and adjust the headband until the ear pads sit comfortably and create a gentle seal. For optimal listening, allow a short break-in period and play familiar tracks to judge tonal balance.

Usage recommendations

Use the HD 599 in quiet, indoor environments to take full advantage of the open-back soundstage. Store the headphones on a stand or in a protective case when not in use and replace ear pads as needed to maintain comfort and hygiene.

Specifications

Microphone type: The characteristics of the microphone bulit into the device in terms of the reception of signals from all or just one direction, i.e. omnidirectional (better for concerts and the like vs unidirectional, more suitable for voice recording.: Not available
Ear coupling: Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression.: Circumaural
Connectivity technology: The technology that enables connectivity of the device, e.g. wired or wireless.: Wired
Headset type: A headset is headphones combined with a microphone, or one headphone with a microphone. Headsets provide the equivalent functionality of a telephone handset but with hands-free operation. Types of headsets include single earpiece (monaural) and double earpiece.: Binaural
Recommended usage: What the product should be used for, and how it should be used (e.g. ambient temperature).: Music
Product type: The sub-category of the product.: Headphones
Product colour: The colour e.g. red, blue, green, black, white.: Ivory, Brown
Wearing style: The way in which the device is worn.: Head-band

Headphones

Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.: 0.1 %
Impedance: The effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance.: 50 Ω
Headphone frequency: The range of frequencies (low to high sounds) that the headphones can produce.: 12 - 38500
Ear coupling: Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes.

In this overview, the Sennheiser HD 599 wired headphones are compared with alternative Sennheiser models: the CX 80U in-ear headphones in white and black, the audiophile HD 600, the replacement headband cushion HZP 30, and the office headset PC 7 USB. All products belong to the same brand but serve completely different purposes—from home music listening and gaming to mobile calls, office work, or equipment maintenance. The main difference of the Sennheiser HD 599 lies in its open circumaural design, high impedance, and extended frequency range, making it a stationary solution for detailed sound immersion, whereas the alternatives represent portable in-ear buds, office mono headsets, specialized open-back models for purists, or spare parts.

⚙️ The specification comparison covers headphone construction, connectivity type, microphone presence, and use cases to help understand the technical differences between the devices.

Comparison parameter	Sennheiser HD 599	Sennheiser CX 80U (White)	Sennheiser CX 80U (Black)	Sennheiser HD 600	Sennheiser HZP 30	Sennheiser PC 7 USB	Practical significance
Device type	Headphones (circumaural)	In-ear wired headphones	In-ear wired headphones	Headphones (supra-aural / open)	Replacement part (cushion)	Headset (monaural)	Different form factors determine noise isolation, wearing comfort, and application scope.
Connectivity	Wired	Wired (USB-C)	Wired	Wired	Not applicable	Wired (USB)	Connection type determines compatibility with PCs, mobile devices, or stationary equipment.
Microphone	Not available	Built-in	Built-in	Not available	Not available	Built-in	Microphone presence is essential for calls, while audiophile models focus purely on listening.
Recommended usage	Music, gaming	Daily use, calls	Daily use, calls	Music	Maintenance	Office, call center	Models are optimized for multimedia, mobility, or work voice communication.

◎ The suitability and use case evaluation helps determine which product best matches the user's specific daily tasks.

Use case	Recommended product	Why
Stationary music listening and gaming at home	Sennheiser HD 599	Provides a wide soundstage, comfortable fit, and high sound detail thanks to the circumaural design.
Daily commutes, multimedia, and phone calls	Sennheiser CX 80U	Compact in-ear format and built-in microphone offer convenient on-the-go use with mobile devices.
Professional music listening for audiophiles	Sennheiser HD 600	Designed for critical listening with exceptional sound clarity and natural reproduction.
Restoring worn-out headphones	Sennheiser HZP 30	Acts as a direct OEM spare part to maintain comfort and extend the service life of compatible models.
Work calls in an office or call center	Sennheiser PC 7 USB	Lightweight monaural design ensures comfort during long communication sessions.

The Sennheiser HD 599 is ideally suited for home entertainment, gaming, and attentive music listening due to its comfortable over-ear design and wide frequency response. Choose it if you value stationary comfort and detailed sound without needing a built-in microphone. If your priority is office calls or listening to media on the move from a phone, the compact or headset alternatives will be more suitable.
