Hey, what’s cracking everyone—this video is my full experience with the HEDDphone D1, HEDD’s first step away (for now) from their AMT driver stuff and into a world-first dynamic driver setup using a Thin Ply Carbon Diaphragm (TPCD). It’s an open-back, $799 headphone that I’ve had in-house for weeks, and I walk you through the unbox/build, comfort, and why the tech here is genuinely interesting. Build-wise it’s a polished, high-end Sennheiser-type vibe: plastic/metal/steel, dual 3.5mm cup connections, velour pads, and it comes with a molded case (plus some pad-cleaning tape in production units). At ~350g, it’s light, comfy, and the clamp is “just right” for me. Sound is where the D1 really hooked me. The big theme is smoothness, but with an analytical edge—fast transients and a kinda “planaresque” speed without that unnatural planar presentation. Bass has solid extension with a bit of sub-bass drop-off, but the sustain keeps it from feeling empty; mid-bass slam is the star. Mids are neutral-but-engaging with rounded upper-mid attack, and treble is airy yet forgiving—great if you’re treble sensitive. I also cover amp synergy (yes, it scales), gaming performance thanks to the wide stage, and comparisons versus the HiFiMAN Audivina (“Dalia”) and Meze 105 AER. At this price, it’s a slam dunk for my preferences and competes with stuff above $1K.
