Wired, Active Noise-Cancelling (ANC) Headphones
After a decade of service, it was time to replace the Bose QuietComfort 20i Acoustic Noise Cancelling headphones referenced in 2015. While non‑Bluetooth ANC models have become increasingly scarce, the Bose QuietComfort Headphones (2023) offer a wired-only mode; Bluetooth is disabled (verified via EMF meter) when the included 2.5mm-to-3.5mm audio cable is connected:
Connect audio cable and turn on headphones (but don't put them on yet)
A female voice announces "Bluetooth off", followed by a loud startup jangle. She then advises, "To start setup, download the Bose Music app", repeating the prompt ~12 seconds later, presumably for the benefit of those temporarily deafend by the clangor. 🔈
Despite being listed in Technical Specifications as "Protein Leather", Bose marketing materials confirm the ear cushions are synthetic (the case is listed as "Leather (Hard)", but is apparently synthetic as well); from their Earbuds vs. headphones: finding the perfect pair for you:
"Bose QuietComfort Headphones live up to their name, created with comfort in mind. They're ultra lightweight, and the earcups are fitted with luxurious synthetic leather (emphasis added) and minimal clamping. You can wear them for an extended period of time without experiencing headaches or aching ear canals."
Bose representatives have reiterated this for related models:
-
"[T]he QuietComfort 35 headphones do not contain any animal products, the cushions are made from 80% rayon and 20% nylon."
-
"Bose uses a synthetic leather material for the ear cushions."
Reports indicate the ear cushions are prone to flaking within a short period (including the Ultra model). Higher-rated third-party headband covers and earpads are available, though some reviews note reduced ANC performance.
