The Sennheiser HD 450BT are inexpensive wireless noise-cancelling headphones that maintain the brand's quality guarantee. Sennheiser has produced several of the best ANC headsets in recent years and the HD 450BT stands out for its price/performance ratio.
Like the company's other headsets, the Sennheiser HD 450BT has a sober and sensible appearance. Nevertheless, they offer great sound, remarkable battery life and very solid active noise cancellation. They are also convenient and support high-definition Bluetooth codecs, such as aptX Low Latency.

Design
They have a mature, sober and elegant appearance. The Sennheiser HD 450BT Bluetooth headphones are available in black and white. They are made of hard plastic and have soft touch pads. They are durable, lightweight, the over-ear cups stay in place and create a good seal to passively isolate you from external noise.
They feel great, although they may be a bit small for some users. The Sennheiser HD 450BTs feature a foldable body, so they are portable and perfect to take anywhere. As for the ports, they integrate a USB-C port for charging and an auxiliary audio jack for wired use (cable included).
Unlike the latest wireless headsets, they do not integrate touch controls. This is understandable since these are inexpensive Bluetooth headphones. That said, the physical buttons work flawlessly and allow you to access your phone's personal assistant, manage playback, volume, answer calls, change songs and activate active noise cancellation.
Connectivity and ANC
Through the Sennheiser Smart Control application you can check the battery status, update the firmware and make equalization adjustments. It features an easy-to-use EQ mapping that allows you to boost bass or treble if desired, for example.
Bluetooth connectivity works flawlessly and supports the aptX Low Latency codec that allows you to synchronize audio and video with less than 40 milliseconds of latency. The Sennheiser HD 450BT are perfect for watching videos or playing games.
One of the best features of the Sennheiser HD 450BT is its ANC. These noise-cancelling headphones completely isolate you from an office and reduce the sound of the street to a minimum. The technology is not as good as that of the Momentum 4 or 3, but it's very solid for the price.

Battery life
Autonomy reaches 30 hours at medium volumes, a great capacity for this price range, on par with much more expensive models. They are charged via the USB-C port and the total process takes approximately two hours.
Sound quality
The Sennheiser HD 450BT headphones produce smooth, rich and balanced audio. No matter what genre of music you want to play, all instruments and vocals sound vivid and detailed. The sound profile is warm and very pleasant.
The tonal balance slightly favors the bass and sacrifices mid-tone clarity a little . It doesn't offer audio as neutral as HiFi headphones, but it's ideal for playing electric guitars and deep bass.
They sound powerful, with strong but defined bass. The vowels also stand out for their clarity and take the necessary central role in the tracks.
Why do we like the Sennheiser HD 450BT?
Their value for money is really excellent. They are comfortable, portable, lightweight, have a long battery life and offer great sound for an inexpensive ANC headset.
Why don't we like them?
They do not integrate touch controls or advanced features like more expensive models. The ANC is not remarkable either, although it's quite solid. In truth, we can't complain too much as they are available for a very attractive price.

Conclusion on the Sennheiser HD 450BT
The Sennheiser HD 450BT are not the best noise-cancelling headphones on the market, nor are they the most full-featured. They do not have the transparency or ANC technology of the latest Sony or Bose, but in their price range they stand out for their performance.
The battery life is among the best, they support aptX Low Latency codec, are comfortable and lightweight. The best part: they offer a nice, warm and pleasant sound. Interested? Find the best prices on Amazon.
