Ich verkaufe meine Sennheiser HDB 630 Bluetooth Kopfhörer, da ich Geld für meinen Urlaub brauche. Es ist ein wirklich wunderbares Gerät und der Klang ist neutral, aber nicht langweilig und in der App lässt sich viel anpassen.
ACHTUNG: Die Kopfhörer haben einen leichten Wasserschaden erlitten, weil sie einmal im Regen liegen gelassen worden sind. Nach Trocknung waren sie aber wieder voll funktionsfähig und ich habe mir im Laden HiFi Klubben mit A/B Testing bestätigen lassen, dass der Klang zumindest nicht hörbar gelitten hat.
Bis auf diesen tragischen Zwischenfall sind sie kaum benutzt und weisen keine Gebrauchsspuren auf und die OVP samt HD Audio Dongle ist auch dabei.
Die Rechnung vom 10.06.2026 kann ich gerne dazu schicken.
Excellent condition helps here, but €350 is still clearly ambitious against the recent used market: the median sits at €128, with the upper quartile at €246, so this asks a solid premium over even stronger-than-average comps. That doesn’t make it absurd, but it does mean the buyer should expect near-new cosmetics, full accessory set, and ideally some remaining warranty or very light use to justify the number.
As a product, this is the kind of Sennheiser wireless headphone that can be worth paying for if the fit, tuning, and noise-canceling features are exactly what you want, but the value case at this price depends on condition and completeness more than the model itself. If the box, cable, case, and pads are all present and genuinely clean, it’s a polished buy for someone prioritizing convenience and premium feel; otherwise, I’d wait for a listing closer to €246 or below.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in June 1945 by Dr. Fritz Sennheiser in a farmhouse near Hanover, Germany, Sennheiser began as Laboratorium Wennebostel, producing voltmeters and early microphones amid post-World War II reconstruction. Seven engineers from the University of Hannover joined the founder, quickly pivoting to broadcast microphones like the DM 2 in 1946 and the groundbreaking MD 82 shotgun mic in 1956. Renamed Sennheiser electronic in 1958, the family-owned company passed to second- and third-generation leadership, maintaining its innovative spirit over eight decades.
Sennheiser excels in professional and consumer audio, renowned for microphones, wireless systems, and headphones that set industry standards. Pioneers of the first open-back headphones (HD 414 in 1968) and enduring studio icons like the MD 421 and MD 441, they also produce high-end headphones, earbuds, soundbars, and conferencing solutions. While strong in pro audio like mixers and geophysical gear, their consumer focus centers on headphones and wireless tech rather than amplifiers, speakers, turntables, DACs, or cables.
Sennheiser commands a premium position in the hi-fi market, blending mid-tier accessibility with high-end excellence for discerning buyers and professionals. Trusted for reliability and sonic precision, it appeals to audiophiles seeking reference-grade headphones without boutique obscurity, backed by a heritage of technological firsts that sustains its global leadership.
