Sennheiser HD 450BT Wireless Headphones

The Sennheiser HD 450BT are wireless over-ear headphones finished in white. They feature active noise cancellation and Bluetooth 5.0 connectivity with support for SBC, AAC, AptX and AptX Low Latency codecs. A built-in lithium-polymer battery provides up to 30 hours of playback with ANC active and recharges via USB-C in approximately two hours.

Ideal for commuters needing long battery life

These headphones suit listeners who want effective noise cancellation for travel or open offices and value high-quality wireless codecs for music and calls. The 238 g circumaural design and touch controls add daily convenience. Buyers who require wired high-resolution audio playback or a lighter on-ear fit should consider other models.

30-hour battery life with ANC enabled

The integrated 600 mAh battery delivers 30 hours of continuous music playback over Bluetooth while active noise cancellation is running. A full charge takes roughly two hours through the USB-C port, and the headphones fold into the supplied carry case for transport. This endurance figure is the key specification for deciding if the HD 450BT matches your usage patterns.
