Drop X Sennheiser PC37X Measurements
Dekoni Audio is pleased to share a “deep dive” look into our Sennheiser Game One line of Earpads, specifically tuned to elevate your listening experience.
We start with comfort, using our soft, high density, slow rebound memory foam for an extra plush experience that conforms to the shape of your face (and accommodates glasses stems). For high quality performance, durability, and feel, we have covered the memory foam with Choice Leather. We ensured the pads mount just as securely as the stock pads. These pads fit a wide variety of headphones, from the legendary Sennheiser HD 598, HD558, modern HD 599 and HD 559, and also the headset champions PC 360, Game One, and Drop Exclusive PC37X, and many more. These do NOT fit the HD 58X Jubilee, but we do make pads for that! Finally, we shaped and measured the pads to tune the sound and share a preview of how they sound compared to stock pads.
In our measurements, we are sharing the raw data except to cancel out the ear response of our microphone dummy head. We have been fortunate to have acquired a certain well-known Audio Precision-based measurement rig, and will continue to keep the measurements coming! Some measurements by others are made with adjustments to reflect the effect that the shape of a generic inner and outer ear will have on the sound waves – we provide the raw data, because as every experienced audio enthusiast knows, we all have different ears! So, as part of a series of Dekoni Describes posts, we will walk our readers through understanding our graphs.
The first thing to understand about an uncompensated graph is that it will sound different to the listener than the graph will show. For one, we haven’t smoothed our graphs, so there are many peaks and valleys that would have been lost information, but also there are other factors, such as the human’s extra sensitivity to vocals, and that the shape of our ears and depth of our ear canals can actually amplify certain frequencies. For the purposes of swapping earpads, it is enough to say that a flat line along the 0 dB line wouldn’t sound “good” on these uncompensated graphs, a dip in the midrange is to be expected since human ears are more sensitive to that region, and mainly we want to focus on how a Dekoni pad compares to the Stock Velour pad.
We use supple, animal-free Choice Leather that is the softest synthetic available today. The graph shows us a similar character to the stock Velour pads, with more midbass over a wide range of frequencies, and a narrow decrease in brightness at about 4 kHz, though overall it has dips and peaks in amplitude in all the same places, keeping the same overall character. If you were a gamer wanting gunshots to sound more meaty but have less fatiguing bite, this is a good pad for you! The Choice Leather is also excellent for trying hard and playing sweaty, because it easily wipes clean with a damp cloth or our safe cleaning products.
Having a hard time seeing how the midrange is mostly similar between the stock and Choice Leather pads? We usually only publish our graphs with the different frequency curves overlaid to line up at 300 Hz for consistency, but if we move them to overlay at the midrange, say around 2.5 kHz, you get the dark purple line as seen here:
The subjective factor of experiencing headphones and earpads matters the most, of course. If it sounds good, it is good! We listen with our pads for several revisions before release, and we want to thank the reviewers and our patrons on Head-Fi and other platforms who have shared their experiences. Real user experience is the best judge, and we thank everyone who has tried to describe their experience!
