· This is a review video of HEDD audio's headphone D1. · HEDD audio is also famous for its monitor speakers, and its headphone lineup includes four models: HEDDphone, HEDDphone 2, GT, and the latest D1 model. · Previous models (HEDDphone, 2, GT) used AMT drivers and had a rectangular design, but the D1 features a circular ear cup and a dynamic driver, showing significant differences in design and structure. · The D1 is HEDD's first dynamic driver headphone, with its most notable feature being the use of a carbon-material TPCD diaphragm. · The price range is in the million-won bracket, and the design is generally well-executed.

· The package includes the headphone itself, a carrying pouch, a 3.5mm bundled cable, and a 6.35mm adapter, keeping it simple. · The cable has a textile cover, making it soft, flexible, and resistant to tangling, though it can feel a bit slippery and heavy. · It's an open-back, over-ear design, making it unsuitable for recording but usable for listening or mix/mastering work. · Key specifications are as follows:

Category	Details
Frequency Response	5Hz - 40kHz
Max Sound Pressure Level (SPL)	100dB
Impedance	32 ohms
Weight	350g

· With a low impedance of 32 ohms, it can be sufficiently driven by standard audio interfaces, and an external headphone amplifier is not strictly necessary. · The earpad material is velour, which is thick and plush, but might feel slightly damp (personal preference). · The cable length is 2m and features a dual-entry connection. · The weight, a previous drawback of earlier models exceeding 500g, has been significantly reduced to 350g in the D1, making it comfortable for extended listening sessions. · The carbon diaphragm combines lightness and rigidity, contributing to a fast, clean, and accurate sound reproduction. · Measurement data also suggests a balanced sound profile without excessive peaks.

· Design: Unremarkable and looks good when worn. (3 out of 5 stars) · Comfort: The ear pads are comfortable, and the headband is slightly firm but holds the head well, making it comfortable for long listening sessions. Despite being open-back, they provide a secure fit with some degree of external noise isolation. (5 out of 5 stars) · Portability: With the provided pouch and cable characteristics, there are no major inconveniences when traveling. (4 out of 5 stars) · Sound: · Overall Balance: No specific frequency range stands out excessively, and all frequency bands are reproduced evenly without masking. · Low Frequencies: The sub-bass isn't overly emphasized but is clean and controlled. It's not a bass-centric headphone. · Mid Frequencies: Not excessive, accurate, and excellent for voice monitoring. They are reproduced with high density and clarity without sounding harsh. · High Frequencies: Balanced without being piercing or thin, with well-controlled issues in the 3-4kHz and above 10kHz ranges. They are not dull or inaccurate. · Resolution: High frequencies are monitored well, allowing you to catch sounds you might not have noticed before. Ear fatigue is also minimal. · Separation: All sounds are clearly distinguishable, with each element performing well in its own space. · Soundstage: Excellent reproduction of spatial effects like reverb and delay, to the point where you can perceive new spatial characteristics. There's no artificial sense of a stage. · Imaging: The stereo image's panning information is very accurate, greatly aiding in positional judgment during mixing. There's no artificial sense of a stage. · Coloration: The sound is presented as-is without added color, fitting for monitoring purposes. · Overall Sound Quality Rating: 5 out of 5 stars, the most satisfying headphone I've heard recently. (5 out of 5 stars) · Value for Money: While the million-won price point isn't cheap, it's well worth the cost considering the excellent sound performance.
