The Sennheiser HD 598 are comfortable open-back headphones with good studio quality sound. They're well built and feel durable but offer no control options for your audio. The open back design also leaks a lot of sound and doesn't block any ambient noise. They're not designed for commuting and may disturb people around you.
The Sennheiser HD 598 are amazingly comfortable and premium looking headphones. The earcups are large enough to fit around most ears, and the headband feels sturdy with a metal frame for reinforcement. Unfortunately, they struggle a little to stay on the head during physical activity and offer no control options for your audio, which is slightly disappointing.
The Sennheiser HD 598 are stylish and look premium. They have an all-black color scheme and silver accents around the large, oval open back ear cups. The padding on the ear cups is a suede-like material, which adds to the premium feel if the headphone. They also come with an ivory and brown color scheme that may be more appealing for some.
The Sennheiser HD 598 are very comfortable headphones. The padding on large ear cups is soft and coated in a suede-like material that feels nice on the skin. They easily fit around most ears and do not apply much pressure to the head, contrary to the Beyerdynamic DT 770. The ear cups may be a little too large for some, but that's the only downside to an otherwise very comfortable listening experience.
The Sennheiser HD 598 are not designed to be very portable. They're bulky, and the earcups do not lay flat to take up less space. They also do not fold up into a more compact format. They are not as big as some of the higher-end models of the same series but are still too cumbersome and will occupy a lot of space in your bag. They also don't come with a case or pouch, which is slightly disappointing.
The Sennheiser HD 598 is a good sounding pair of open-back over-ear headphones. They have a good Bass, a very good Mid Range and an excellent Treble. They also perform relatively consistently across multiple individuals and have a good Soundstage, mainly due to their open-back design. However, their Bass lacks sub-bass, they sound muddy in the lower Mid Range, and they tend to be a bit sharp and sibilant in the Treble Range. Additionally, their distortion performance could be better as they tend to distort with bass-heavy tracks at very loud volumes.
The Sennheiser HD 598 are open back headphones that are not designed to isolate and fair poorly in loud environments. They do not have active noise cancellation, and the open back ear cups let a lot of ambient noise seep into your audio. They also leak a lot as part of their design to improve sound, which makes these headphones unideal for commuting or traveling and may disturb the people around you, even on a bus.
Poor isolation. These headphones don't isolate any sound below 2KHz, which is typical of open-back headphones and by design. Above 2KHz, they perform very poorly, failing to achieve more than 10dB of overall attenuation in the treble range.
Poor leakage. These open headphones leak a lot of sound throughout a broad range of frequencies. The leakage starts to become noticeable around 300Hz and remains so up to 20KHz.
