Know before you buy
With an impedance of 69 Ω and a sensitivity of 90 dB/mW, the Diana TC requires a high-quality dedicated headphone amplifier to perform at its best. A powerful desktop amplifier is recommended to fully realize the dynamics and resolution these planar drivers are capable of.
The Diana TC is designed for extended wear, weighing in at 390 grams. It features the 2021 generation ear pads and an EMotion headband, which uses high-quality leather and soft Alcantara to distribute weight evenly and minimize fatigue.
No, the Diana TC is an open-back headphone design. While they provide excellent soundstage and transparency, they do not offer active noise cancellation and will allow external sound in, making them best suited for quiet, critical listening environments.
The Diana TC utilizes large 63 mm patented planar drivers that are exceptionally fast, resulting in a sound signature characterized by deep, textured bass and a very expansive soundstage. They are tuned to be highly transparent and refined, offering a balance of sparkling treble and full-bodied mids.
While you can technically connect them to a portable device, the Diana TC is designed for audiophile-grade setups. To achieve the intended sound quality and volume levels, you will likely need a high-output portable DAC/amp rather than plugging them directly into a standard phone or laptop.
The headphones are highly versatile regarding connectivity. You can choose from 2.5 mm balanced, 3.5 mm, 4.4 mm balanced, 6.3 mm stereo, or 4-pin XLR terminations to match your specific amplifier setup.
