Enjoy stylish comfort and audiophile-grade sound quality with the HD 550 from Sennheiser, over-ear, open-back headphones ideal for gaming and everyday listening. Sporting a balanced and transparent sound profile with a wide 6 Hz to 39.5 kHz frequency range, and a weight of just 8.3 oz, these headphones are built for long, immersive listening sessions.

The HD 550 delivers high-quality sound with punchy bass, neutral mids (for voice intelligibility), and an airy, open treble response. The open-back design provides a wide soundstage and excellent breathability for enhanced comfort. Every element of the design has been refined to balance sound quality with lightweight comfort. The headphones feature the robust and reliable mechanical design of the HD 500 series. The HD 550 sports a detachable cable, and the input jack on the earcup is balanced, allowing for use with balanced headphone amps or optionally with a microphone, transforming the HD 550 into a premium gaming headset. The Sennheiser HD 550 includes a drawstring bag, a 3.5mm audio cable, and a 3.5mm to 1/4" TRS plug adapter.

Refined Sound Quality

The Sennheiser HD 550 headphones feature audiophile-grade sound quality thanks to a dynamic transducer with an improved laminate diaphragm, providing extended bass and treble response. The lighter voice coil also delivers a more transparent sound.

1. Extremely wide 6 Hz to 39.5 kHz frequency range
2. Laminate Duofoil membrane and a lightweight voice coil reduce unwanted resonances for optimal transient response
3. 150-ohm impedance for great audio performance on most playback devices including headphone amps
4. Acoustic foam absorbs unwanted sounds, for better treble reproduction and a more controlled bass response
5. Open-back design with mesh material avoids reflections for a truly open soundstage
6. Acoustically transparent dust cover ensures pure transmission between transducer and eardrum

Frequency Response Analysis

The HD 550s are designed to provide a highly balanced frequency response:

1. Punchy bass that is well embedded in the very low frequencies, providing less warmth than the HD 599 but a more balanced treble response
2. Neutral midrange makes voices and instruments shine and is free from unwanted coloring
3. Precise and airy treble that's free from narrow-band resonances and strong in the highest octave

Solid Build Quality

Utilizing the trusted mechanical design of the HD 500series headphones, the HD 550 headphones are built with high-grade metal mesh (no plastic) on the headband and reliable components throughout, with aftermarket spares available if needed.

Exceptional Wearing Comfort

The headband is designed with reduced clamping force for a comfortable and secure fit. The headphones are extremely lightweight, allowing for extending listening sessions without strain. With velour foam earpads, synthetic leather headband, and an airy open-back design, these headphones are built to feel like there's nothing covering your ears.
