AI Verdict
A 7.1-ounce open-back headphone with a 5-36,000 Hz frequency response and two distinct ear pad tunings, designed for critical audio production and comfortable long sessions.
These headphones are a strong fit for professional audio work and extended listening due to their 7.1-ounce weight, dual ear pad options for sound tuning and comfort, and wide 5-36,000 Hz frequency response. The open-back design and precise imaging cater directly to critical listening needs in controlled environments.

Pros
- Open-back design delivers an extremely wide, dimensional sound stage with ultra-precise localization.
- Uncolored frequency response (5 - 36,000 Hz) provides honest, dynamic sound reproduction across the full spectrum.
- Weighing 7.1 ounces (260g) with soft velour pads, these headphones are reported as exceptionally comfortable for extended wear.
- Includes two unique sets of ear pads, allowing users to switch between a warmer, 'producing' sound profile and a more neutral, 'mixing' sound profile.
- Features right and left ear jacks with a detachable cable, adapting easily to various studio configurations and blocking cable-borne noise.
- Easy to drive with 130-ohm impedance and 101 dB SPL sensitivity, making them compatible with laptops and mobile devices without a powerful amplifier.
Cons
- Open-back design offers minimal isolation against background noise and leaks significant audio, making them unsuitable for noisy environments or quiet shared spaces.
- The fabric 'mixing' ear pads can feel scratchy and shallow, causing some users' ears to touch the driver cover, reducing comfort.
- Switching between the two sets of ear pads is described as difficult and fumbly.
- The velour 'producing' pads can result in bass that sounds 'thicker and slower and borderline muddy' on certain tracks.
- Embossed 'L' and 'R' indicators on the inside of the earcups can cause irritation or 'tickle' the ear for some users, especially with the shallower mixing pads.
Dimension Scores
The 5-36,000 Hz uncolored frequency response and two distinct ear pad tunings provide highly accurate and adaptable sound reproduction for professional use.
As open-back headphones, they offer no active noise cancellation and minimal passive noise isolation, leaking significant sound.
Weighing 7.1 ounces (260g) with soft velour pads and a light clamp force, these are frequently cited as exceptionally comfortable for long sessions, though the mixing pads can be less comfortable.
These are wired headphones and do not have a battery.
Best For
- Audio engineers and producers needing accurate sound reproduction for mixing and mastering in a quiet studio environment.
- Individuals requiring comfortable headphones for very long listening or production sessions.
- Gamers who prioritize precise sound imaging and a wide soundstage for positional audio cues.
- Users who want the flexibility of two distinct sound profiles for different stages of audio work or listening preferences.
Not Recommended For
- Commuters or travelers needing noise isolation in loud environments.
- Office workers in shared spaces where sound leakage would be disruptive.
- Individuals seeking headphones for sports or fitness activities due to their bulky size and open-back design.
Watch Out For
- The fabric 'mixing' ear pads are reported to be scratchy and shallow, potentially causing ears to touch the driver cover, which can be irritating.
- Swapping the ear pads is a fumbly process that can take a couple of minutes.
- The embossed 'L' and 'R' markings inside the earcups can rub against the ear, causing discomfort or a 'tickling' sensation for some users.
- While the soundstage is wide, some users find the overall presentation for music to be 'congested' or 'in my head,' lacking immersion compared to other open-back headphones.
- The 'producing' velour pads, while more comfortable, can make the bass sound 'thicker and slower and borderline muddy' on certain music tracks.

What Buyers Say
The most surprising finding is how much the two included ear pads alter the sound profile and comfort, with users often preferring the velour 'producing' pads for comfort despite the fabric 'mixing' pads offering a more neutral sound. Many users highlight the exceptional comfort for long sessions, often comparing it favorably to much more expensive headphones. However, some find the soundstage, while wide, can feel 'congested' for music, and the embossed 'L' and 'R' inside the earcups can cause physical irritation. The open-back nature means zero noise isolation, which is a consistent point of awareness for buyers.
“Dude, these are SO comfy, I wore 'em for like six hours straight mixing a track and my ears didn't even hurt. The velour pads are where it's at, but man, trying to swap 'em out is a pain. Sound is super clear though, just don't try to use 'em on the bus, everyone will hear your jams.”
Common Praise
- The soundstage is extremely wide and dimensional, providing ultra-precise localization.
- Exceptional comfort, especially with the velour 'producing' pads, allowing for hours of wear without fatigue.
- Accurate and uncolored frequency response (5-36,000 Hz) for critical listening.
- Excellent imaging, described as spherical, which is beneficial for gaming and spatial audio.
- Good bass extension, offering more low-end presence than some other Sennheiser open-backs like the HD 600/650.
- Easy to drive, working well directly from laptops and phones without needing a powerful amp.
Common Complaints
- The fabric 'mixing' pads are often described as scratchy and shallow, causing ears to touch the driver cover.
- The open-back design means no noise isolation and significant sound leakage, making them unsuitable for public or noisy environments.
- Some users find the velour 'producing' pads can make the bass sound 'borderline muddy' on certain tracks.
- The embossed 'L' and 'R' inside the earcups can rub against the ear, causing irritation.
- Switching between the two sets of ear pads is a difficult and fumbly process.
- Despite a wide soundstage, some listeners perceive the music presentation as 'congested' or 'in my head' rather than immersive.
Ownership Tips
- The velour 'producing' pads are generally preferred for comfort, even if the fabric 'mixing' pads offer a more neutral sound profile.
- The headphones are surprisingly easy to drive, often not requiring a dedicated amplifier even with their 130-ohm impedance.
- The open-back nature means you'll hear everything around you, and everyone around you will hear your audio, so a quiet environment is essential.
- While lightweight, the plastic build, though sturdy, might not feel as premium or robust as all-metal alternatives over long-term, heavy use.
- The ability to detach the cable from either ear cup is a small but appreciated convenience for studio setups.
Frequently Asked Questions
Do these headphones require a dedicated amplifier?
No, with a 130-ohm impedance and 101 dB SPL sensitivity, the HD 490 PRO are efficient enough to be driven by a laptop or mobile device without a powerful amplifier.
Are the ear pads replaceable and washable?
Yes, the ear pads are both replaceable and washable, contributing to the product's sustainability-inspired design.
Can I use these headphones for gaming?
Yes, users report excellent spherical imaging and a wide soundstage, which can be highly beneficial for precise positional audio in gaming.
What is the difference between the two sets of ear pads?
One set of ear pads (velour 'producing' pads) offers a warmer, more relaxed sound with enhanced low-end, while the other (fabric 'mixing' pads) provides a more linear, neutral, and honest sound profile.
Do these headphones block out external noise?
No, as open-back headphones, they provide minimal noise isolation and will allow external sounds to be audible, while also leaking sound to those around you.
Buying Guide
When you're looking at professional open-back headphones like these, you're buying into a specific listening experience. You'll get incredibly accurate sound and a wide soundstage, which is crucial for tasks like mixing music where you need to pinpoint every detail. But because they're 'open-back,' they don't block out any noise from your surroundings, and everyone around you will hear what you're listening to. So, if you're in a noisy place or a shared office, these aren't going to work for you.
Open-back design
Think of it like listening to speakers in a room, but on your head. This design allows air to move freely, creating a wider, more natural soundstage and preventing pressure buildup, which helps with accurate sound reproduction and reduces listening fatigue. The trade-off is zero noise isolation.
Frequency response (5 - 36,000 Hz)
This range tells you how low and high the headphones can reproduce sound. A wide range like 5-36,000 Hz means they can handle very deep bass and very high treble frequencies, giving you a full and detailed audio picture, which is essential for professional audio work to catch all nuances.
Two unique sets of ear pads
This is like having two different pairs of headphones in one. Each pad type subtly changes the sound profile – one might emphasize neutrality for mixing, while the other offers a slightly warmer, more 'musical' sound for general listening or producing. It also impacts comfort, so you can pick what feels best for your ears.
Weight (7.1 ounces)
For headphones you'll wear for hours, weight is a huge deal. At 7.1 ounces (260g), these are relatively light, which directly translates to less pressure on your head and neck, making them much more comfortable for those marathon studio sessions or long listening periods.
Alternatives
If these don't fit, look for closed-back headphones with active noise cancellation if you need to block out sound, or headphones with a built-in microphone if communication is a priority.
