Feature-by-Feature Breakdown
Sound Quality
- Superlux Hd668b: Known for a relatively neutral and balanced sound profile with good detail retrieval. The bass is present but not overpowering, mids are clear, and highs are generally well-extended without being sibilant. Some may find them a bit analytical for casual listening.
- Hd681 Evo: Often described as having a more V-shaped sound signature, meaning boosted bass and treble with recessed mids. This can make them sound more exciting and energetic for certain genres, but can also lead to fatigue for some listeners and mask finer details in the midrange.
- Winner: superlux hd668b
Soundstage and Imaging
- Superlux Hd668b: Offers a respectable soundstage for its price point, providing a decent sense of space and separation. Imaging is generally accurate, allowing for good placement of instruments within the soundscape.
- Hd681 Evo: Tends to have a wider soundstage than the HD668B, contributing to its more immersive and “open” feel. Imaging can be good but may sometimes feel slightly less precise due to the more pronounced V-shaped signature.
- Winner: hd681 evo
Comfort and Build Quality
- Superlux Hd668b: Features a semi-open design with velour earpads that are generally comfortable for extended wear. The build is predominantly plastic but feels reasonably robust for its cost. The self-adjusting headband is a unique feature.
- Hd681 Evo: Also a semi-open headphone with pleather earpads, which can get warmer than velour. The build is similar in its plastic construction, and while adequate, might not feel as premium as some other options.
- Winner: superlux hd668b
Bass Response
- Superlux Hd668b: The bass is well-defined and controlled, offering a good balance with the rest of the frequency spectrum. It’s present and impactful when called for but doesn’t bleed into the mids or dominate the sound.
- Hd681 Evo: Features a more prominent and impactful bass response, often described as “punchy.” This can be enjoyable for genres like electronic music or hip-hop, but may be considered excessive or boomy by listeners who prefer a more neutral bass.
- Winner: superlux hd668b
Treble Response
- Superlux Hd668b: The treble is generally clear and detailed without being overly harsh or sibilant. It provides a good sense of air and sparkle, contributing to the overall clarity of the sound.
- Hd681 Evo: The treble is often boosted, which can add excitement and detail, but also carries a higher risk of sounding sharp or fatiguing, especially at higher volumes or for those sensitive to higher frequencies.

Midrange Performance
- Superlux Hd668b: The midrange is a strong point, offering clear and articulate vocals and instruments. It’s well-balanced and allows for good separation of different vocal and instrumental elements.
- Hd681 Evo: The midrange can be slightly recessed due to the V-shaped tuning. This means vocals and instruments might not have the same presence or forwardness as on the HD668B, potentially getting a bit lost behind the boosted bass and treble.

Portability and Accessories
- Superlux Hd668b: Comes with a detachable cable and a carrying pouch, making it somewhat portable. The detachable cable is a significant plus for durability and customization.

Frequently Asked Questions
Which is better for gaming?
For gaming, the HD681 Evo often takes the lead due to its more exciting sound signature. The enhanced bass can provide a more impactful experience for explosions and action, while the slightly more forward treble can help pinpoint subtle in-game cues. The HD668B offers a wider soundstage, which can be beneficial for spatial awareness, but its more neutral presentation might feel less engaging for some gamers.
Which has better bass?
The HD681 Evo generally presents a more prominent and impactful bass response compared to the HD668B. While the HD668B’s bass is present and well-defined, it’s more integrated into the overall sound profile. If you’re looking for that extra thump and rumble, particularly for genres like electronic music or hip-hop, the HD681 Evo is the clearer choice. The HD668B’s bass is more about quality and texture than sheer quantity.
Which is more comfortable for long listening sessions?
Both headphones are generally comfortable, but the HD668B often receives slightly higher marks for long-term wear. Its unique self-adjusting headband is designed to distribute pressure evenly across the head, reducing clamping force and hot spots. The velour earpads on both contribute to breathability.

Which is better for critical listening and music production?
For critical listening and budget-friendly music production, the HD668B is generally the preferred option.

While specific replacement pads might be harder to source directly from Superlux, many third-party earpad manufacturers offer compatible options. This is a significant advantage for the longevity of both headphones, allowing you to refresh them if the original pads wear out over time.
Final Verdict
Both the Superlux HD668B and HD681 Evo offer exceptional value, but they cater to slightly different needs. The HD668B excels with its neutral sound, comfortable fit, and robust build, making it ideal for critical listening and general use. The HD681 Evo shines with its energetic sound, enhanced bass, and engaging presentation, perfect for casual listening and genres that benefit from excitement.
