Zo goed ala nieuw. Niet zo oud
This is a fair ask. At €50, it sits just above the median recent asking price of €47 and a touch over the 75th percentile of €49, so it’s not a bargain, but it’s close enough to market that it reads as reasonable rather than ambitious.
The upside here is straightforward: these replacement pads are well-liked for improving comfort, sealing better on the head, and preserving a balanced HD 820 tuning without turning it into something unfamiliar. If the set is clean, properly fitted, and the foam still has good rebound, this is the kind of accessory buy that makes sense for someone actually using the headphone rather than chasing a collector item. Only slow down if wear is obvious or if mounting hardware is incomplete.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Dekoni Audio is a U.S. headphone-accessories brand founded in 2015, with founder Tal Kocen publicly identified in company and professional profiles; the company is based in New Jersey and grew out of a stated goal of improving headphone comfort. Its heritage is therefore relatively recent rather than legacy hi-fi, and it sits in the modern personal-audio ecosystem rather than the traditional loudspeaker or electronics world.
The brand is best known for replacement ear pads, ear tips, and related headphone accessories, especially premium pads for popular models from Bose, Beats, Audio-Technica and other major headphone makers. Dekoni also offers a smaller range of headphones and audio parts, but it is not primarily known for amplifiers, speakers, turntables, DACs, or cables. Its core identity is accessory-led: comfort, fit, and tuning upgrades for existing headphones.
In the market, Dekoni occupies a niche boutique / enthusiast-accessory position rather than a high-end component brand. It is widely associated with aftermarket upgrades for audiophiles and gamers who want to change comfort, seal, or sound character without replacing the headphone itself. For buyers, that makes Dekoni more of a specialist add-on brand than a full-systems hi-fi manufacturer.
