Der Akku hält keine vollen 12 Std. mehr, eher 3 Stunden.

The condition note is crucial, but at €70 this sits exactly on the €70 median of three comparable listings—fair, rather than a bargain. It is well below the €98 upper quartile, so the asking price is sensible if the headphones are clean and fully functional; less so if the pads are tired or the battery is weak.
The QC35 remains a very capable travel headphone: genuinely comfortable, effective noise cancellation, reliable Bluetooth, and up to 20 hours of wireless use. The foldable design and wired fallback add practical value, especially with the case and cables included. Check battery runtime, charging, both channels, buttons, hinges, and ear-pad condition before buying; replacement pads are straightforward, but a tired battery or intermittent electronics can quickly erode the value.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Bose Corporation traces its roots to 1964, when MIT professor Amar Gopal Bose founded the company in Natick, Massachusetts, after growing disillusioned with the poor performance of a high-end stereo system he purchased as a graduate student. Driven by a passion for replicating the immersive qualities of live music through rigorous acoustic research, Bose launched the venture with initial contracts for the U.S. military and NASA, emphasizing innovative speaker designs that prioritized indirect, reverberant sound over direct radiation. This American heritage, rooted in psychoacoustics and engineering excellence, has defined the brand's pursuit of "Better Sound Through Research."
Bose excels in consumer and professional audio categories, renowned for its home audio systems, premium speakers like the iconic 901 Series, and pioneering noise-canceling headphones first prototyped in the 1980s for pilots. The lineup extends to vehicle sound systems, portable Bluetooth speakers, and professional installations, but steers clear of niche hi-fi components such as amplifiers, turntables, DACs, or cables, focusing instead on integrated, user-friendly solutions that blend advanced signal processing with spatial audio reproduction.
Positioned as a premium mid-tier powerhouse in the global market, Bose commands widespread appeal among discerning buyers seeking accessible high-performance audio without audiophile esoterica. Its reputation for innovation and reliability has built a loyal following, though purists occasionally critique its measured sound signature, cementing Bose as a dominant force in mainstream hi-fi rather than high-end boutique or vintage realms.
