What Is a Bose QuietComfort 45 Headphones Worth in 2026? Resale Price Guide

What this piece actually is

The Bose QuietComfort 45 is a wireless over-ear noise-cancelling headphone released in late 2021 as the successor to the long-running QuietComfort 35 II. It uses Bluetooth 5.1, charges via USB-C, carries an advertised 24-hour battery life, and uses physical buttons rather than touch controls. It pairs through the Bose Music app, which is also the only way to get firmware updates and tweak ANC/Aware mode settings. Models come in Black, White Smoke, Eclipse Grey, and Midnight Blue, with the latter two arriving in mid-2022 refreshes.

What is it worth right now?

Based on current live eBay listings for the Bose QuietComfort 45 Headphones, prices run roughly $49.99–$229.99, with a median around $106.50. That puts a typical mid-market resale near $106.50. The gap between the cheapest listings and the median is about $56.51, and that spread is exactly the room condition, completeness, and color move within. This is a live-market estimate, not a fixed price.

What drives the price up

A complete set with the original zippered hard case, USB-C charging cable, and 3.5mm audio cable pulls noticeably more than a “headphones only” sale, because buyers who paid full retail expect the full kit. Clean, intact ear cushions without flaking or peeling are the single biggest condition factor — this is the part buyers scrutinize hardest because replacement pads cost real money and never feel quite like stock. Updated firmware (checked and updated via the Bose Music app before listing) signals a well-cared-for unit. Less common colors like Eclipse Grey or Midnight Blue tend to move faster than the ubiquitous Black.

What drags the price down

The QC line is notorious for ear-cushion deterioration, where the foam inside the pad disintegrates and the surface leatherette flakes off — this is the number one condition defect and instantly drops value. Rattles or looseness in the headband sliders, often caused by the plastic inserts wearing down, is a common deal-breaker. Bluetooth pairing failures, static in ANC mode, a battery that dies in under a few hours, or a headband that has lost its clamping force all knock value down significantly. Smelly or visibly stained pads, missing serial number stickers (located inside the headband under the slider), and any cosmetic cracks on the plastic yokes also hurt.

Is it worth buying at a garage sale?

Yes, this is one of the better headphones to find secondhand because Bose owners often upgrade to the QC Ultra or QC Headphones and clear out older units without researching the resale market. Do a quick functional check before paying: power on (slide the right earcup switch up toward the Bluetooth icon and listen for the power-up tone), confirm both sides produce sound by playing music, look closely at the ear pads for any peeling, and try pairing to your phone. If they power up, pair cleanly, and the pads look intact, you are likely getting a strong deal at a garage or estate sale price.

Should you sell it locally or ship it?

Local pickup on Facebook Marketplace or Craigslist is the easier path because the buyer can test the headphones on the spot, which removes the biggest objection (does it actually work and pair). For shipping, use the original hard case packed inside a snug box with padding — the case protects against the drop and crush damage that USPS and UPS handlers routinely inflict, and shipping insurance is worth the small cost for a headphone this heavy. Ship only after a full reset (hold the power switch to the Bluetooth icon for 10 seconds until you hear “Ready to connect” or see the Bluetooth light blinking blue) so the new owner gets a clean pairing slate.

When you should NOT sell it right now

Skip selling if the ear pads are peeling or the foam is visibly crumbling — replace them first, as a QC45 with fresh pads fetches meaningfully more than the same unit with ratty pads. Also hold off if the battery only lasts an hour or two, because buyers will notice immediately and either lowball or walk away. Do not list it without confirming the Bose Music app recognizes the unit, since a failed app handshake often signals a counterfeit or a unit with a hardware fault a buyer will discover later.

How do I tell if it is authentic?

Genuine QC45s have a specific weight and a solid, creak-free feel to the headband adjustment — counterfeits often feel lighter and the slider action is gritty or loose. The Bose wordmark on each earcup is crisp, evenly spaced, and recessed; fakes tend to have raised, slightly off-center lettering. Open the Bose Music app and attempt to add the headphones — authentic units pair in seconds and display the correct model name and serial number, while counterfeits either fail to pair to the app or show up as generic “Bose” devices. Check the serial number on the inside of the headband (visible when you slide the ear cup adjustment up) against the Bose support database if you want extra certainty. Original cases have a molded Bose logo on the inside mesh and a specific interior shape; replica cases tend to be shallower and lack the embossed branding.
