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.
Noise Canceling Control
The Sennheiser HD 598 maintain a stable fit during casual listening sessions. Unfortunately, they are not designed for sports and are unideal for use during high-intensity activities. They will slip off your ears while running or jumping.

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 have above-average build quality, but weak joints. The headband is reinforced with a metal frame, and they feel sturdy enough to withstand a fair amount of physical stress. Unfortunately, the swivel hinges feel a little weak and susceptible to damage.
Comes with two cables; a 1/8" TRS-TRS with no inline controls and a 1/4" TRS-TRS also with no inline controls.
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. Above 2KHz, they perform very poorly, failing to achieve more than 10dB of overall attenuation in the treble range.
Overall Leakage @ 1ft
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.
No active features.
