Sennheiser hd 477 koptelefoon let op - geen draadloze koptelefoon kabel is rond de 3 meter in goede staat ! Doet het prima !
At €25, this Sennheiser HD 477 is a genuine bargain, sitting well below its original €40 retail price and far under any realistic used-market median for an open over-ear model from its era.
The HD 477 is a respected low-budget, open over-ear headphone from 2002–2006, praised for its simple, sturdy build and home-use comfort with replaceable velour pads. Its 35Ω dynamic drivers deliver 99dB/mW efficiency and a solid 118dB SPL, making it easy to drive and pleasant for casual listening. At this price, even with the dual-sided 2.5mm connector and 3m cable, it’s a smart buy for enthusiasts seeking a lightweight, fold-free option at a rock-bottom cost—no caveats needed unless the pads are worn or the cable split is frayed.

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.
