Wireless Headphones for Daily Use

The Sennheiser HD 450BT Black is a circumaural over-ear headphone built for listeners who want wireless freedom with active noise cancellation. It targets commuters, office workers and home users seeking a single pair for music, calls and podcasts without a cable tether. Bluetooth 5.0 connectivity keeps the link stable across compatible phones, tablets and computers.

Bluetooth 5.0 and Wired Flexibility

Pair the headphones to any Bluetooth 5.0 source for cable-free playback, or plug in the supplied audio cable when wireless is not an option or the battery runs flat. The USB-C port handles charging only and reaches full capacity in roughly two hours. On-board controls and a dedicated Virtual Assistant button give quick access to Siri or Google Assistant without reaching for the device.

30-Hour Battery with ANC Active

A built-in 3.7 V 600 mAh lithium-polymer cell delivers up to 30 hours of music playback with noise cancellation switched on. The 18 Hz to 22 kHz frequency response covers the full audible range while total harmonic distortion stays below 0.3 % at 1 kHz and 100 dB. Buyers needing more than 30 hours between charges or aptX Adaptive support should look elsewhere.
