The Bose QuietComfort SE Headphones are an excellent choice for users seeking industry-leading noise cancellation, signature Bose sound quality, and supreme comfort. Often a special edition or retailer-specific version of the popular QuietComfort 45, the SE model maintains all the core performance features of its counterpart.

Legendary Quiet and Premium Sound

• World-Class Active Noise Cancellation: The QuietComfort SE utilizes Bose’s advanced ANC technology to effectively silence the world around you, allowing for deep focus on your music, work, or simply peace and quiet.
• Two Listening Modes: Easily switch between Quiet Mode for maximum noise isolation and Aware Mode (Transparency Mode), which allows you to hear your surroundings and have natural conversations without removing the headphones.
• High-Fidelity Audio: The headphones are designed with proprietary acoustic technology to deliver deep, clear audio. Users can also access the Bose Music app to utilize the Adjustable EQ and customize the bass, mid-range, and treble to their personal preferences.

All-Day Comfort and Endurance

• Luxurious Design: Known for exceptional comfort, the headphones feature plush, cushioned earcups and a secure, lightweight headband, making them ideal for marathon listening sessions or long flights.
• Extended Battery Life: Enjoy up to 24 hours of wireless listening on a single charge. When time is short, a 15-minute quick charge via the USB-C port provides up to 3 hours of playtime. They also include a $2.5\text{mm}$ to $3.5\text{mm}$ audio cable for endless listening in wired mode.
• Seamless Control and Connectivity: The headphones use reliable Bluetooth 5.1 for a strong wireless connection and feature physical buttons on the earcups for intuitive control over music, volume, and calls. The Bose Music app allows for feature customization and software updates.

The Bose QuietComfort SE headphones are technically and sonically the same as the QuietComfort 45 model. The primary and often only difference is the Soft Carry Case included with the SE version, which offers less rigidity than the traditional hard case that comes with the standard QC45. This makes the SE a functionally identical, high-value alternative.
