Overview

The Bose QuietComfort 45 wireless headphones continue the legacy of one of the most recognized names in noise cancellation. Equipped with tiny microphones that continuously measure and counteract ambient noise, these over-ear headphones create a remarkably quiet listening environment whether you are on a plane, in an office, or working from a busy café. The TriPort acoustic architecture pairs with volume-optimized Active EQ to deliver full, balanced sound at any volume level — bass stays present when you turn it down, and clarity holds when you push it up.

Comfort is a defining feature of the QC45. The ear cups use plush synthetic leather cushioning and the headband is built with impact-resistant nylon, all engineered with minimal clamping force for all-day wearability. On the practical side, the 24-hour battery ensures you can get through a full day of use on a single USB-C charge, and the 15-minute quick-charge option makes it easy to top off before heading out. Bluetooth 5.1 provides a reliable wireless connection, while the included audio cable gives you a wired backup when battery life is not an option. The Bose Music app rounds out the experience with guided setup, noise cancellation adjustments, and device management.

Key Features

High-fidelity audio – The TriPort acoustic architecture offers depth and fullness. Volume-optimized Active EQ maintains balanced performance at any volume, so bass stays consistent when turned down and the music remains clear when turned up.

Quiet & Aware Modes – Choose Quiet Mode for full noise cancelling, or Aware Mode to bring the outside into the around ear headphones and hear your environment and your music at the same time.

Over ear headphones – These comfortable wireless headphones are suitable for all-day wear. Crafted with plush synthetic leather and impact-resistant nylon, and designed with minimal clamping force, they’re as luxurious as they are durable.

Up to 24 hours battery life – Enjoy 24 hours of battery life from a single charge.* A quick 15-minute charge offers 3 hours when you’re on the go, or plug in the included audio cable to listen for even longer in wired mode.

Around ear headphones charge via USB-C – Headphones charge via the included USB-C cable.
