Design and Build Quality
The Sennheiser HD 550 boasts a design strikingly similar to the HD 505, but with a key visual difference: a muted gray colorway instead of the HD 505's copper finish. The overall chassis, featuring a single-arm yolk structure, is a point of contention, with some finding it dated.
While the colorway is a matter of personal preference, the build quality is robust, though not quite as premium as the HD 6 series. The grill is a lighter gray, adding to the overall aesthetic. Upon closer inspection after removing the earpads, the baffle material appears different—a black nylon-like material compared to the white, paper-textured baffle of the HD 505.
Comfort and Fit
Comfort is subjective, and opinions vary. Some find the HD 550 and HD 505 more comfortable than the HD 6 series due to less clamping force, allowing them to "disappear" on the head.
However, others prefer the even clamping pressure and better headband distribution of the HD 6 series. The HD 550's plastic arms, unlike the adjustable metal arms of the HD 6 series, offer less adjustability for clamping force and head size. Earpad contact with the yolk structure is also a point of contention for some, though it may not be an issue for all users.
Sound Quality and Performance
The Sennheiser HD 550 delivers a generally neutral sound signature, leaning slightly towards a dry and lean presentation, particularly in the lower mid-range and bass. This is in contrast to the warmer, more forward character of the HD 6 series.
The mid-range is exceptionally clear and well-balanced, though lacking the romantic warmth of some HD 6 series headphones. The treble is articulated but can be perceived as slightly gritty in places. The soundstage is described as more spacious than the HD 6x0, providing better separation between instruments.
Comparisons and Conclusion
The HD 550 is considered a significant upgrade from older 5 series headphones like the HD 598. Compared to the HD 505, the HD 550 offers a more balanced mid-range. While very similar, the HD 550 is generally preferred to the HD 505 due to a more refined overall sound.
The HD 550 is an excellent headphone overall, but the HD 6xx remains a strong contender due to its lower price point. The HD 550 is easier to drive, making it a better choice for users without dedicated headphone amps. Ultimately, the best choice depends on individual preferences and priorities, including budget, sound signature preferences, and the availability of the HD 6xx.
