Sennheiser HD 450BT Overview
Enjoy your audio in peace, even outside, with the HD 450BT Noise-Canceling Wireless Over-Ear Headphones from Sennheiser. Thanks to active noise cancellation technology, ambient sounds are filtered out, leaving you alone with your favorite songs, podcasts, and more. Thanks to Bluetooth 5.0 technology, you can enjoy your audio almost anywhere without any cumbersome wires.
Support for AAC, aptX, and aptX Low Latency codecs is meant to enhance your listening experience, but you can further tweak your sound to your specific tastes with the Smart Control app's built-in equalizer. Dual beamforming MEMS microphones built-in provide additional functionality on top of pure listening enjoyment. Pair them with your smartphone for hands-free calls, and use the dedicated digital assistant button to interface with Siri or Google Assistant. Ask questions or use your voice to manage calls and playback.
All-Day Battery
The HD 450BT headphones have been given a sizable battery so you don't have to worry about recharging them during the day. Even with Bluetooth and active noise cancellation in use, you'll get up to 30 hours of power.
Podcast Mode
Engage Podcast Mode on the Smart Control app to automatically optimize audio to help make the person speaking more intelligible. It's an ideal mode for not just podcasts, but for audio books and other speech-related content.
