Overview

In the world of affordable audio gear, the Superlux HD681 has earned a reputation as a legendary budget king for those who value performance over flashy branding. Looking at the physical frame, you will immediately notice design cues taken from classic professional studio monitors, though the build quality remains strictly utilitarian. These wired headphones prioritize an analytical listening experience, offering a semi-open construction that feels remarkably lightweight on the head. While the materials are mostly plastic, the structure serves its purpose well for anyone needing a functional tool rather than a luxury accessory. It is a straightforward piece of equipment that focuses its value almost entirely on the internals, making it a staple recommendation for newcomers in the audiophile community who are looking for their first pair of real monitors.

Features & Benefits

The heart of these semi-open cans lies in the large 50mm neodymium drivers, which provide an expansive frequency range that reaches surprisingly deep and high. Because of the semi-open back design, you get a much more natural soundstage compared to the claustrophobic feel of typical closed-back models. Comfort is handled by a self-adjusting headband system that automatically finds the right fit for various head sizes without manual clicking or sliding. With a low impedance of only 32 ohms, the studio monitors are easy to drive directly from a laptop or smartphone without needing a bulky external amplifier. Furthermore, the 2.5-meter single-sided cable offers enough length to move around your desk or workstation without the constant frustration of tangled cords or limited range of motion during long sessions.

Best For

If you are an entry-level home studio producer working on a strict equipment budget, these wired headphones are practically essential for critical mixing tasks. They also serve as a fantastic tool for gamers who prioritize spatial awareness and a wide soundstage over total noise isolation, allowing for better tracking of in-game environmental cues. For those involved in podcast editing, the clarity provided here makes it simple to catch subtle vocal pops or background hiss that cheaper consumer buds would likely mask. Even casual listeners looking to move beyond standard-grade audio will find plenty to like here, provided they do not need to use them in public. Since these semi-open cans leak sound by design, they are best reserved for quiet home offices or dedicated studio environments where privacy is not a primary concern.

User Feedback

Long-term owners frequently praise the impressive high-end detail and instrument separation found in these semi-open cans. However, the experience is not without its quirks, as the stock vinyl earpads tend to get quite warm during extended listening marathons. Some users also mention a prominent treble spike that can feel a bit piercing for those with sensitive hearing, though this can often be tamed with simple modifications. Another point to consider is the non-detachable cable, which raises some long-term durability questions if the cord gets snagged. Despite these minor gripes, the general consensus points toward an unbeatable value for the price. Many enthusiasts actually suggest a quick earpad upgrade to improve comfort, which helps transform the studio monitors from a capable tool into a much more refined listening companion for daily use.

Audio Resolution
91%
Users are consistently shocked by the level of instrument separation and detail these semi-open cans provide at this price point. The 50mm drivers capture subtle nuances in recordings that usually require much more expensive gear, making them excellent for critical listening.
The clinical nature of the sound means low-quality recordings or harsh digital artifacts are exposed without mercy. Some listeners find the clarity almost too aggressive for casual, relaxed listening sessions where a smoother profile might be preferred.
Value for Money
98%
The performance-to-price ratio is frequently described as unbeatable by the audiophile community. These studio monitors punch significantly above their weight class, offering a technical performance that often rivals headphones costing three to four times as much.
While the sound is elite for the price, the cost savings are clearly visible in the packaging and accessories. You are paying strictly for the drivers and acoustic engineering rather than a premium unboxing experience or high-end materials.
Soundstage Width
88%
Thanks to the semi-open back design, these wired headphones offer an airy and spacious presentation. Gamers especially appreciate how this helps with spatial awareness and pinpointing directional cues like footsteps or distant gunfire in open-world environments.
Because of that same open design, sound leaks out significantly into the surrounding room. This makes them completely unsuitable for library use, public commuting, or office environments where your audio might disturb colleagues or family members nearby.
Treble Accuracy
64%
36%
The high-end response is incredibly crisp, bringing out the sparkle in cymbals and the breathiness in vocal tracks. For editors and mixers, this brightness helps highlight sibilance or high-frequency noise that needs to be addressed in the final edit.
A prominent treble spike is a major point of contention, with many users finding the highs piercing or fatiguing after an hour. If you are sensitive to bright audio, these may require EQ adjustments to prevent ear strain during long mixing sessions.
Long-Term Comfort
57%
43%
The self-adjusting headband system is a highlight, automatically distributing the weight across the head without needing manual clicks. The overall frame is very lightweight, which helps prevent the typical pressure on the neck often associated with bulky professional gear.
The stock vinyl earpads are the biggest drawback, as they do not breathe well and can cause sweat buildup quickly. Many long-term users recommend budgeting for aftermarket velour pads to resolve the heat and stiffness issues reported during extended use.
Bass Impact
79%
21%
The low-end is surprisingly present and punchy for a semi-open design, providing a solid foundation for classical and orchestral music. It avoids the bloated or muddy sound found in cheap consumer headphones, staying tight and controlled during dynamic passages.
Sub-bass enthusiasts might find the roll-off a bit too early compared to dedicated closed-back models. It lacks the physical "thump" that bass-heavy genres like modern EDM or hip-hop typically require for a truly immersive listening experience.
Build Quality
68%
32%
Despite the mostly plastic construction, the frame is resilient and can survive the occasional drop or rough handling in a home studio. The utilitarian design means there are fewer complex moving parts or hinges that are prone to snapping over time.
The materials feel thin and "cheap" to the touch, lacking the robust feel of higher-end professional equipment. Creaking sounds from the plastic joints are occasionally reported when moving your head or adjusting the fit during active use.
Cable Durability
71%
29%
The 2.5-meter cable is thick and feels durable enough for heavy daily use at a desk or workstation. The single-sided entry is a practical touch that keeps the wire out of your way while playing instruments or typing on a keyboard.
The cable is permanently attached, which is a significant failure point; if the wire shorts out, the entire unit becomes useless without a soldering iron. Its length is also quite cumbersome for portable use with a phone or laptop on the go.
Driveability
93%
With a low 32-ohm impedance, these studio monitors can be powered to high volumes by almost any device. You do not need an expensive dedicated headphone amplifier to get the full frequency response and detail out of the drivers.
While an amp is not required, the transparency of the drivers will reveal the hiss or poor quality of a cheap onboard soundcard. Using them with a low-quality source might result in a slightly thinner sound than what they are truly capable of.
Portability
46%
54%
A simple carrying pouch is included in the box to keep dust off the drivers when they are not in use. Their light weight makes them easy to toss into a backpack if you are moving between different home studio setups.
The large, non-folding circular earcups and long, non-detachable cable make these a nightmare for travel. They take up a lot of space in a bag and are simply too bulky and leaky for use in any mobile or public context.

Suitable for:

The Superlux HD681 is a standout choice for aspiring audio engineers and budget-conscious home studio producers who need accurate, analytical sound without a premium price tag. Because of the semi-open back design, these wired headphones are also excellent for gamers who want a wide soundstage for better spatial awareness during competitive play. Podcast editors will find the detailed high-end response useful for catching small vocal errors or background noise during the editing process. They serve as a perfect entry point for casual listeners who want to experience high-fidelity audio for the first time without a massive investment. The lightweight frame ensures they stay relatively comfortable during long mixing or gaming marathons at a dedicated desk.

Not suitable for:

The Superlux HD681 is not the right fit for anyone needing to use headphones in public spaces like libraries or on a daily commute because the semi-open design leaks sound significantly. Listeners who are sensitive to bright or "piercing" high frequencies might find the prominent treble spike quite fatiguing during long sessions. Additionally, the non-detachable cable makes these less ideal for users who are rough on their gear and want the security of a replaceable cord. If you are looking for deep, rattling sub-bass for modern EDM, the analytical tuning here may feel a bit too thin for your tastes. Finally, those who prioritize premium materials will likely be disappointed by the strictly utilitarian and plastic-heavy build quality of the frame.

FAQ

Not at all; since these semi-open cans have a low impedance of 32 ohms, they work perfectly fine plugged directly into your laptop, phone, or gaming controller. You won't need any extra equipment to get plenty of volume.

I wouldn't recommend it for tracking vocals because the semi-open design leaks sound, which your microphone will likely pick up as background noise. This "bleed" can make it difficult to get a clean vocal take during the mixing stage.

The Superlux HD681 features a clever self-adjusting wing system that automatically slides into place when you put them on, so you don't have to fiddle with clicking plastic sliders.

Yes, while the stock vinyl pads are fixed fairly securely, you can swap them out for aftermarket velour or sheepskin pads. Many users find this simple mod significantly improves long-term comfort and helps with heat management.

No, the 2.5-meter cable is permanently attached to the left earcup. You'll want to be careful not to snag it or run it over with your desk chair, as you can't simply swap out the wire if it gets damaged.

Likely yes, as the back of the earcups is partially open to the air, meaning sound escapes easily into quiet rooms. We generally recommend using these in private studio settings rather than a quiet office.

They include a soft protective carrying pouch, but because the studio monitors don't fold, they still take up a fair amount of space in a backpack or suitcase.

This refers to a specific boost in the high frequencies that makes details like cymbals or vocal sibilance stand out. While this is great for analytical mixing, it can feel a bit sharp or fatiguing for those with sensitive ears.

Absolutely; the included screw-on 1/4-inch adapter makes these wired headphones compatible with most guitar amplifiers and professional mixing consoles. It provides a secure connection that won't accidentally pull loose during a session.

You can simply wipe the vinyl pads down with a slightly damp microfiber cloth to remove sweat or oils after a long session. Just make sure to keep moisture away from the drivers themselves.
