The video is a comprehensive review of the Sennheiser HD 450 SC wireless over-ear headphones, with a particular focus on their key features, build quality, and audio performance. The host highlights the headphones' active noise-cancelling capabilities, Bluetooth 5.0 connectivity, and Amazon Alexa compatibility. The build consists of high-quality plastic, contributing to a sturdy design that includes foldability for portability. Comfort issues such as heat buildup and a strong clamping force are noted but may ease with use.
Control features on the headphones include buttons for power, Bluetooth pairing, volume, media playback, and voice assistant functions compatible with Amazon Alexa, Siri, and Google Assistant. The review also touches on the headphones' decent vocal transmission via a dual beam-forming microphone array, although lacking auto play/pause functionality and extensive app settings for noise cancellation. The Active Noise Cancellation (ANC) is described as basic, with only moderate effectiveness on lower frequency noises, unlike competitors such as the Sony WH-1000XM4 and Soundcore Life Q35, which offer more advanced ANC and additional features.
Sound quality remains consistent whether ANC is on or off, with a neutral sound signature praised for its balanced frequency handling across bass, mid-range, and treble. The host concludes by recommending the HD 450 SC for those seeking a combination of neutral sound, good build quality, and essential ANC features, noting its good battery life and the added benefit of Alexa compatibility over the HD 450BT model. Finally, the host thanks viewers and encourages them to engage with the content through likes, subscriptions, and comments.

In this part of the video, the host reviews the Sennheiser HD 450 SC wireless over-ear headphones, highlighting their active noise-cancelling feature and Amazon Alexa compatibility. The headphones weigh around 240 grams and the headband has a strong clamping force, which may feel tight for those with larger heads but should be comfortable for most users. The padding on the headband is thin, yet the overall comfort improves after some use. There is an issue with heat buildup inside the ear cups, particularly in warmer conditions, and the ear cups offer limited space but provide good passive noise isolation.
The materials used in the headphones are high-quality plastic, making them well-built with no squeaking noises. The headphones can be folded for portability, although the ear cups don’t fold completely flat. The box includes a USB-C charging cable and an audio cable with 2.5mm and 3.5mm connectors. The audio cable locks into the headphones to prevent accidental disconnection, and the active noise cancellation feature can still be used with the cable connected, provided the battery is charged. The battery life is approximately 30 hours on a single charge.

In this part of the video, the presenter discusses the features and functionalities of the Sennheiser HD450SC headphones. Key points include the use of Bluetooth 5.0 with various codecs for a reliable wireless connection and multi-point support for connecting two devices simultaneously.

The controls are described in detail: the right earcup houses multiple buttons including the power button (also used for Bluetooth pairing and ANC toggle), a volume rocker, a multi-function button for media playback control, and a voice assistant button by default set to Amazon Alexa. These headphones are compatible with Siri and Google Assistant as well.
The video also mentions the absence of auto play/pause functionality due to the lack of on-ear sensors and highlights a limited smartphone app that mainly supports software updates and EQ adjustments. Lastly, the presenter touches upon the lack of settings for active noise cancellation within the app, only allowing for ANC to be turned on or off.

In this segment, the reviewer discusses the Active Noise Cancellation (ANC) performance of the HD450SE headphones, noting it’s not very powerful and only slightly reduces lower frequency noises. Comparisons are made with the Sony 0000 X Mark IV, highlighting the latter’s superior ANC, and the Soundcore Life Q35, which also performs better and offers additional software features like transparency mode. Positively, the HD450SE maintains sound quality whether ANC is on or off, without any hiss or cabin pressure. The reviewer praises the HD450SE’s neutral sound signature, balanced frequency handling, and satisfactory bass, mid-range, and treble. They conclude that the HD450SE is a good choice for those seeking neutral sound, good build quality, basic ANC features, and good battery life, while noting its main difference from the similar HD450BT model is the added Alexa compatibility.
