Bose QuietComfort 25

Yes, the active noise cancellation feature requires a single AAA battery to operate. While the headphones will still produce sound without a battery, the noise cancellation and audio amplification features will not work.

The inline remote and microphone are specifically optimized for Apple iOS devices. While you can use the headphones for audio on Android or other devices with a 3.5mm jack, the volume and playback controls may not function as intended.

The QuietComfort 25 is designed specifically for long-term wear. The lightweight frame and plush ear cushions minimize pressure, making them a reliable choice for multi-hour use without causing fatigue.

Yes, the integrated inline microphone allows you to take calls. It is designed to pick up your voice clearly, though it works best in quieter environments since it is a wired, non-directional mic.

The foldable design is engineered for portability, allowing the headphones to collapse into a compact size for your bag. While convenient, the hinges are standard for this model, so it is recommended to use the included carrying case to protect them when not in use.

Refreshed components indicate that the unit has been inspected and updated with new parts to ensure it meets performance standards. This ensures the noise cancellation and audio drivers function like new, backed by a 6-month CentralSound warranty.
