Here’s a detailed overview of the Sennheiser HD 599 open‑back wired headphones—considered a gateway into audiophile‑grade listening:

🎧 Overview & Specs

  • Type: Around-ear open-back headphones

  • Drivers: Excellent frequency range (~12 Hz–38 kHz), ~50 Ω impedance (~106 dB/V SPL), THD < 0.1% 

  • In the Box:

    • 3 m cable with 6.3 mm plug

    • 1.2 m cable with 3.5 mm plug (consumer-friendly)

    • 6.3 → 3.5 mm adapter 

  • Comfort & Build: Lightweight plastic with thick velour ear-pads and minimal clamp force—comfortable for very long listening sessions 

🔊 Sound Quality & Performance

  • Sound Signature: Mildly warm with elevated upper‑bass (around 200–250 Hz), giving a slightly “veiled” or mellow feel.

  • Midrange: Clean and smooth; vocals and instruments are well-presented though sometimes less forward in male voices 

  • Bass: Present but not deep/sub-bass-rich—some users find it lacking punch in genres like hip-hop or EDM .

  • Treble & Resolution: Generally smooth with subtle detail; prevents listening fatigue but may feel recessed to listeners preferring more sparkle 

  • Soundstage & Imaging: Spacious and immersive, especially for its price—provides a concert-hall feel and good instrument positioning 

🧠 Community Feedback

  • Some users found them muddy or lacking clarity without EQ or a headphone amp:

    “sound muddy … vocals … drowned” 
    “muddy bass … veiled vocals”

  • Others praised the comfort and flexibility:

    “Most comfortable headphone I’ve ever used … clamp force practically nonexistent” 

  • EQ tuning can significantly improve clarity and balance for many users:

    “With EQ, the 599’s sound great … nothing really ‘punches out’ … it’s all very mellowed and far away” 

✅ Pros & Cons at a Glance

✅ Pros ❌ Cons
Spacious open-back sound with natural imaging No passive isolation; sound leakage
Smooth, comfortable fit—ideal for long listening Slight mid-bass boom can veil vocals or mids
Good mid clarity and pleasant tonal balance Bass may lack sub-frequency depth
Detachable cables for versatile use Bass lovers or bright-sound fans may be underwhelmed
Excellent value—often discounted heavily Sensitive to source/amplifier quality

 

🏁 Verdict

The Sennheiser HD 599 offer exceptional comfort and a refined, spacious listening experience for home use. They're ideal if you're exploring detailed music listening—jazz, classical, acoustics—where neutrality and soundstage matter more than massive bass or portability.

Best for you if you:

  • Listen in quiet environments at home or office

  • Want airy soundstage and balanced tonality

  • Prefer comfortable, long-session wear

  • Appreciate value-driven audiophile gear

Maybe look elsewhere if you:

  • Listen on the go or need passive noise isolation

  • Prefer punchy, forward bass-heavy sound

  • Rely on a phone or low-end device without dedicated amplification

  • Want bright, energetic treble or vivid tonal presentation
