Sennheiser HD599 SE Headphone Review: Accurate Bass & Open Back

Introduction

The Sennheiser HD599 SE sits in a unique space, promising near-audiophile sound quality with open-back comfort at a price that fluctuates from wallet-friendly deals to premium territory. Is this model the value-packed performer it claims to be, or does it fall short when scrutinized for critical listening, gaming, and everyday enjoyment? This comprehensive review provides unbiased editorial analysis for audiophiles, gamers, and discerning listeners.

Overview and Unboxing

Sennheiser’s “Special Edition” HD599 is marketed as a near-audiophile model. Its open-back design distinguishes it from closed-back studio cans, targeting those who crave both spacious sound and natural bass. The build, featuring all-plastic construction with velour ear pads and a pleather headband, maintains a lightweight profile ideal for extended wear. Included are two detachable cables—one short with a 3.5mm jack, and a longer one terminating in a 6.3mm plug, plus a 6.3mm-to-3.5mm adapter for extensive device compatibility.

Sound Analysis

Frequency Response

A critical frequency sweep reveals the HD599 SE excels in low-frequency delivery but exhibits a dip between 1.5–2kHz and in the 10kHz region. This tonal shaping grants robust bass—a rarity in open-back headphones—but also leaves the mids and highs sounding somewhat recessed. On logarithmic analysis, there’s a noticeable emphasis just above 100Hz up through 500Hz, reinforcing the bass-forward profile.

Real-World Listening: Music

Audio tests with multiple genres corroborate the frequency findings. The pronounced bass enhances genres like EDM and hip-hop, while the slightly muted mid-high range imparts a “dullness” that may not suit classical or acoustic purists. Minor equalization can easily brighten the top end, restoring presence without sacrificing balance.

Vocals

Both male and female voices come through with clarity, though some subtle detail is lost in the upper frequencies. For vocal-rich music or spoken word, the HD599 SE does a capable job but lacks the airiness audiophiles might expect from higher-end open-backs.

Gaming Performance

Extended gaming sessions show the HD599 SE blends the punchy bass of closed-back headphones with a decently wide soundstage. While its stage is not as expansive as some rivals, its imaging accuracy is impressive, making it a solid pick for both immersive and competitive gaming. Comfort over hours of use is excellent—even during long sessions, thanks to its light build and plush pads.

Comfort and Build

The fit is forgiving for most head shapes, although minimal movement in the ear cup swivel might press on the bottom of the ears for some users. The lightweight plastic keeps fatigue low. Valour pads and a padded headband set the HD599 SE ahead of competitors at this price-point for all-day wear. Build quality is solid, but not luxurious—par for the course in this segment.

Value

Perhaps the most important caveat is pricing. At a sale price, the HD599 SE outperforms much of the competition, particularly for open-back fans who want strong bass. At MSRP, though, other models might offer more balanced sound or refined build.

Pros and Cons

Pros:

• Outstanding bass for an open-back headphone
• Lightweight, comfortable design
• Detachable cables, generous included accessories
• Excellent for gaming and casual listening

Cons:

• Upper mids and treble are slightly recessed (“dull” sound for some)
• Minimal swiveling in ear cups affects fit for certain users
• Soundstage less expansive than higher-end open-backs
• Price volatility can impact relative value

Final Verdict

The Sennheiser HD599 SE is best for listeners who want an open-back headphone with punchy bass and solid comfort—especially if purchased on sale. It performs reliably for gaming and everyday music, and with a bit of EQ, can adapt to more critical applications. At its best price, the HD599 SE is an easy recommendation. At full retail, however, those seeking ultra-detailed mid and high frequencies may want to shop around.
