AI Appraisal Estimate

This item is a pair of Bose QuietComfort 35 II over-ear noise-cancelling headphones in a silver metallic finish. The construction features plastic earcups with an integrated pivoting frame, a fabric/Alcantara-lined headband for comfort, and synthetic protein leather earpads. The exterior of each earcup prominently displays the 'BOSE' brand logo in raised lettering. Key physical features include a power/Bluetooth toggle switch on the right earcup, along with micro-perforated microphone grilles for noise cancellation and voice pickup. The headband is adjustable and utilizes a metal reinforcing band hidden within the padding. Regarding condition, the headphones show significant signs of heavy use and wear. The Alcantara lining on the underside of the headband is visibly soiled and discolored. The synthetic leather on the earpads is cracked and peeling (flaking), which is common for this model over time. There are minor scratches and scuffs on the silver plastic housing of the earcups. These headphones were originally manufactured by Bose Corporation between 2017 and 2021. Despite the cosmetic wear, the structural integrity appears intact, though the pads would require replacement for hygienic and aesthetic restoration.

I have completed a visual examination of the Bose QuietComfort 35 II headphones in silver. The item exhibits authentic design language, including the correct laser-etched logo placement and distinct dual-microphone grilles. However, the condition is poor to fair. The top Alcantara headband shows significant moisture discoloration and staining, while the protein leather earpads are in a state of advanced degradation (flaking), which is typical for this model but necessitates immediate replacement. Market conditions for the QC35 II remain steady due to its high-quality noise cancellation, but as older tech (superseded by the QC45 and QC Ultra), value is largely driven by cosmetic state. Similar units in 'parts only' or 'heavy wear' condition typically sell for under $70, whereas mint units can fetch $120. The primary value detracting factor here is the cost and labor required for sanitation and ear-cushion replacement. Note that this appraisal is based solely on digital images. A full authentication would require a physical inspection to verify the internal serial number via the Bose Connect app and a functional check of the battery health and driver clarity. I cannot verify the integrity of the internal lithium-ion battery or the active noise-cancelling circuit functionality without a tactile and auditory test.
