Sennheiser HD 450BT Wireless Headphones
The HD 450BT uses a dynamic around-ear headphone design engineered for a closed listening experience.
Sennheiser officially specifies a frequency response of 18Hz to 22,000Hz and sound-pressure level of 108 dB at 1kHz, 0dBFS. Total harmonic distortion is listed at less than 0.3% at 1kHz and 100dB.
The tuning is positioned around clear overall reproduction with deep dynamic bass, making the headset suitable for music, films, podcasts and general multimedia.

Active Noise Cancellation
A major feature of the HD 450BT is Active Noise Cancellation, designed to reduce selected ambient sounds so users can concentrate more easily on their audio.
This can be particularly useful during commuting, flights, office work or other environments with persistent background noise.
ANC effectiveness varies according to frequency and fit, so the headphones should not be marketed as eliminating every external sound completely.
The closed around-ear construction also contributes passive isolation by physically covering the ears.
Bluetooth 5.0 Connectivity
The HD 450BT uses Bluetooth 5.0 and supports A2DP, AVRCP, HFP and HSP profiles.
This allows compatible smartphones, tablets, laptops and other Bluetooth audio devices to connect wirelessly for music and calls.
The headset supports several audio codecs:
- SBC
- AAC
- aptX
- aptX Low Latency
Codec selection depends on the connected device. A phone or computer must also support the relevant codec for it to be used.
aptX Low Latency Support
The presence of aptX Low Latency is particularly useful when audio/video synchronisation matters.
Sennheiser specifically highlights the codec as part of the HD 450BT’s wireless audio capability.
With a compatible transmitter or source device, lower latency can improve lip-sync performance during movies and videos compared with standard Bluetooth configurations.
It should not automatically be marketed as a dedicated gaming headset, because actual latency depends on the transmitting device and codec support.
Up to 30 Hours Battery Life
Sennheiser rates the HD 450BT for up to 30 hours of operating time.
That extended runtime can cover multiple workdays, journeys or entertainment sessions without frequent charging.
Actual battery life varies according to volume, Bluetooth conditions, ANC usage and battery age.
Charging takes approximately two hours through the USB Type-C connection.
USB-C also provides a more convenient modern connector compared with older micro-USB charging designs.
Optional Wired Listening
The HD 450BT can also be used with its supplied 1.5-metre audio cable.
Sennheiser specifies a 3.5mm angled adapter/connector and includes the audio cable in the package.
This provides an alternative listening method when users prefer a wired connection or are connecting to equipment without Bluetooth.
The package also includes a USB-C charging cable and carry case.
Customers looking at both wired and wireless models can browse Nikshan’s headset collection.
Dual-Beamforming Microphones
Sennheiser officially lists a Dual Beamforming microphone arrangement with a microphone frequency response of 80Hz–6,000Hz.
The microphones support hands-free calling when connected to compatible Bluetooth devices.
Call quality depends on environmental noise, phone connection and microphone positioning, so it is better to describe them as built-in dual-beamforming microphones rather than promising studio-quality voice pickup.
Sennheiser Smart Control App
The headphones work with the Sennheiser Smart Control App.
Sennheiser states that the app allows users to adjust EQ settings, monitor battery level, receive firmware updates and use features such as Podcast Mode.
Podcast Mode is designed to improve speech-focused content such as podcasts and audiobooks.
The app therefore adds useful personalisation beyond the physical controls on the headphones.
Foldable Around-Ear Design
The HD 450BT weighs approximately 238 g and uses a compact folding design.
Its foldable construction makes it easier to place inside the supplied carry case during travel or storage.
Sennheiser describes the headphones as around-ear rather than simply generic “over-ear,” with the earcups designed to surround the ears.
Comfort can vary according to ear shape and head size, so users should take breaks during extended listening if required.
