A Look at the AKG K501's History and Design

The AKG K501, released in 1996, holds a unique place in audio history. It followed a line of predecessors, including the K240 DF (1985) and the K1000 (1990), marking a significant step in AKG's headphone evolution. The K501's design, while an evolution, clearly shows its lineage from the K240, retaining the swiveling earcups and the cable routing over the headband.

The construction incorporates a leather headband and fabric earpads, a step up from the vinyl of its predecessors. Gold accents add a touch of high-end flair. Although generally well-built, some users report issues with the headband's elasticity over time, requiring adjustments or replacement.

The earcups use a twist-lock mechanism for pad replacement, although this can be somewhat fiddly. The internal components are more complex than the outward design suggests; a detailed look requires dismantling the headphone.

Comfort and Ergonomics

While not uncomfortable, the AKG K501's comfort is not its strongest point. The leather headband, while initially supple, hardens with age, potentially causing pressure points. The fabric earpads are on the firmer side, a trade-off for longevity and sound quality.

The double headband system, a tried-and-true AKG design, provides adequate clamping force. However, the overall comfort is best described as 'adequate'—not exceptional, but not severely flawed either. The comfort level is a compromise made in the pursuit of long-lasting performance and accurate audio reproduction.

Sound Quality and Performance

The AKG K501's sound signature is quite unique. It shares more similarities with the K500 than the K240. It boasts an open, spacious soundstage, characterized by a light, delicate yet articulate and even aggressive presentation. The midrange and upper midrange/treble are exceptionally well-tuned, offering exceptional detail and clarity.

However, the bass response is significantly rolled off, meaning it lacks the deep, impactful bass found in many modern headphones. This makes it less ideal for bass-heavy genres like modern pop or electronic music. This tuning makes them perfect for detailed classical and acoustic genres.

Comparison and Conclusion

Compared to modern AKG headphones and other high-end models, the K501's lack of bass response is a noticeable shortcoming. Modern headphones often achieve a more balanced frequency response. The AKG K501's strengths lie in its exceptional midrange and treble clarity, making it exceptional for classical music, but less versatile for other genres.

While it doesn't compete with modern headphones offering more balanced sound across the frequency spectrum, the K501 remains a significant piece of headphone history. Its dedication to accuracy in the midrange and treble provides a unique listening experience, particularly for classical music enthusiasts. However, its significant lack of bass might make it less appealing to listeners preferring a more modern, full-bodied sound signature.
