SENNHEISER
HD 505 Open-back Audiophile Headphones (Special Copper Edition) (Hong Kong Import)
Detailed introduction
SENNHEISER HD 505 is the entry-level choice for audiophile sound, featuring Sennheiser's own 120Ω angled dynamic drivers manufactured in their Ireland factory, delivering clear analytical sound from 12 Hz to 38.5 kHz. The open design combined with high-quality metal mesh ear cups creates a stage-like sound field — the saxophone is slightly to the left, the piano is positioned at the back right, with details clearly defined. Weighing only 237 g and designed with low clamping force, the artificial leather headband and velvet ear pads ensure comfort for long listening sessions, watching movies, or gaming. The durable German engineering design is compatible with the entire HD 500 series, with replacement parts like ear pads available for long-term supply.
Use cases
🎵 Beginner Enthusiasts
The best choice for first-time users of open-back headphones — no need for an expensive amplifier, good sound directly driven by 120Ω impedance smartphones and computers, and the detail analysis allows you to hear something new in familiar songs.
🎬 Watch movies and play video games
The open sound field makes movie dialogue and sound effects more realistic; it is ultra-lightweight at 237g with low clamping force, so it won't pinch your head or cause ear discomfort even after wearing it for a long time.
🏠 Home-based Quiet Listening
The velvet ear pads are breathable and comfortable, allowing you to quietly listen to vinyl records and streaming Hi-Res music alone at night and experience the most subtle spatial sense in the recording.
Why choose this model?
- Want to experience Sennheiser's audiophile-grade open-back sound at an entry-level price?
- Prioritizing comfort — ultralight at 237g + low clamping force + velvet ear pads
- Pursuing a durable and repairable design — long-term parts supply and full compatibility with HD 500 series accessories.

Frequently Asked Questions (FAQ)
Q. What's the difference between HD 505 and HD 550/HD 599?
HD 505 is the entry-level model of the 500 series, with an impedance of 120Ω, making it easier to drive than the HD 550 (150Ω), suitable for direct use with mobile phones and computers; the sound signature inherits the analytical power of the HD 599 and extends the bass. If you have a higher budget and want more details, you may consider the HD 550.
Q. Do I need to use an amplifier (ear amplifier)?
No need. 120Ω impedance, 107.9 dB sensitivity, can be directly driven by general mobile phones, computers, and DAP; of course, pairing with a headphone amplifier will provide better dynamic performance.
Q. Do open-back headphones leak sound?
Yes. The open design allows sound leakage, and you can also hear ambient sounds, making it suitable for quiet home environments but not ideal for public transportation or shared office spaces.
Q. Can I replace my broken ear pads?
Sure. Sennheiser promises long-term supply of parts, with ear pads, cables, and other accessories fully compatible with the HD 500 series (HD 505/550/559/569/599/560S/620S). Additionally, a 4.4mm balanced cable and HD 500 BAM boom microphone can be optionally selected to transform it into a gaming set.
