Compared with the obvious alternative—ordinary working Bluetooth headphones at €100—this is a gamble, but the price is still a strong bargain for a parts donor. Recent comparable asking prices centre at €108, with the lower quartile at €82 and upper quartile at €153, so €100 is slightly below the market median but not an extraordinary bargain for a non-working unit. Its value depends heavily on what “for parts” actually means.
AirPods Max remain desirable for their excellent noise cancellation, spacious sound, premium construction, comfortable magnetic pads, and seamless Apple-device integration. They also have useful salvage value: cushions, headband, drivers, microphones, and electronics can be individually worthwhile, and the design is moderately serviceable. Before buying, establish whether it powers on, charges, pairs, and produces sound in either cup; liquid damage, condensation, battery failure, or flex-cable faults can quickly make €100 poor value. For a capable tinkerer or donor requirement, though, this is a sensible low-end entry.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
