Sennheiser, a renowned name in the audio industry, has launched its latest entry-level open-back headphone, the HD 550. This new model shares several features with the recently released HD 505 Copper Edition, which debuted just last month, making it an exciting addition to Sennheiser’s lineup for audiophiles and casual listeners alike.
Key Features of the HD 550
The HD 550 is equipped with 38mm dynamic drivers, similar to its predecessor. However, it boasts a slightly wider frequency response range of 6Hz – 39.5kHz, compared to the 12Hz – 38.5kHz of the HD 505. Additionally, the HD 550 has a marginally higher impedance of 150 Ohms, as opposed to the 120 Ohms found in the HD 505. These specifications suggest that the HD 550 may deliver a more nuanced sound experience, appealing to those who appreciate high-quality audio.
Craftsmanship and Design
One of the standout features of the HD 550 is that its drivers are manufactured in Sennheiser’s Tullamore factory, the same facility responsible for producing the legendary HD 650 and HD 800 S headphones. This connection to Sennheiser’s heritage of excellence in audio engineering adds to the anticipation surrounding the HD 550.
The open-back design of the HD 550 is intended to provide a more acoustically transparent sound, allowing for a natural listening experience. While the physical design closely resembles that of the HD 505, a notable difference lies in the filter used to cover the driver. The impact of this change on the headphone’s sound signature will be intriguing to explore.
