Technology: Bluetooth 5.0 and strong battery life
For wireless transmission, the HD 450BT relies on Bluetooth 5.0 and supports not only SBC and AAC but also AptX and AptX Low Latency – important for anyone who wants to keep audio and video in sync, for example, when listening to music while traveling or on the train. The manufacturer states a battery life of up to 30 hours, and it charges via USB-C. If you need to quickly recharge on the go, you'll benefit from the short charging time of around two hours to full capacity.
Active Noise Cancelling for focused listening
The active noise cancelling is designed to reduce ambient noise, allowing for undisturbed music listening even in loud environments. In terms of sound, Sennheiser uses a dynamic transducer with a frequency range of 18 Hz to 22,000 Hz and a sound pressure level of 108 dB – values that indicate a powerful, bass-heavy sound character, as the manufacturer itself promotes.
Design and operation
Weighing 238 grams and featuring a foldable headband, the HD 450BT is designed for travel and is available in black or white. Additional settings such as an equalizer or a podcast mode can be made via the Sennheiser Smart Control App. For wired listening, a 1.5-meter jack cable is included.
