Sennheiser HD 450BT review | What Hi-Fi?

Sennheiser headphones infrequently wish to grab your attention with bold designs or out-there features - the emblem’s robust reputation speaks for itself. The German emblem has produced very good wi-fi and noise-cancelling headphones, most particularly the fashions in its iconic Momentum differ, roughly since such ideas were invented.

So when the reasonably plain-looking, button-heavy Sennheiser HD 450BT wi-fi noise-cancellers land in our laps, we all know all too smartly now not to judge them by means of their quilt.


We are first of all a little upset through the mid-range cans, regardless that – no longer such a lot via the understated design, which is powerful and neatly finished in black or white, however by the controls. The world is more and more transferring on from bodily buttons and against touch, gesture and voice control, and when you shouldn’t be expecting an reasonably priced pair of headphones comparable to those to adopt an advanced (and expensive) system, nor should it's a must to blindly navigate this kind of busy button format.

Each button has its objective, after all. The one closest to the connector mechanism launches your phone’s voice assistant. Run your finger down the earcup and you’ll find a slider for play/pause and answering calls, skipping forward and backward tracks. There’s also a quantity button, which you'll be able to manipulate for volume up and down with an appropriate press. 

Further around the earcup is every other button, separated from the rest via a USB-C charging socket and a 2.5mm audio jack for plugging in the provided 2.5mm-to-3.5mm cable. This button turns on noise-cancelling and powers the headphones on and off.

Learning such an association isn’t past the average consumer, however it does prevent temporarily and instinctively attaining for the correct button.

The Sennheiser HD 450BTs are light and durable on your head, with the earpads clamping firmly over your ears to supply isolation and save you undesirable motion. They might feel slightly tight on higher heads at first, but that are supposed to ease through the years. Thanks to their reassuring construct and foldable design, you won’t be afraid to sling their compactly folded shape right into a bag or cram them right into a coat pocket.


A 30-hour battery existence, which can also be replenished in just two hours by means of their USB-C charging port, places them on a par with the pricier, premium festival and in truth pips that of Sennheiser’s flagship on-ears, the Momentum 3 Wirelesses

Battery standing may also be viewed at the Sennheiser Smart Control App, which could also be the gateway to performing firmware updates and adjusting EQ.

On the latter, you'll be able to drag a pointer around an equalisation map to regulate the steadiness in opposition to extra bass or treble. There’s no harm in favouring either to get a little extra low-end domination or top-end sparkle even if, predictably, going excessive either means makes them lovely unlistenable. 

Bluetooth is entire with aptX Low Latency make stronger for syncing up audio and video (with not up to Forty milliseconds of latency) when you’re watching a video or playing a game to your attached tool.

The Sennheiser’s wirelessness is complemented via noise-cancelling. True to the generation’s purpose, the HD 450BTs sheath you in a comfy silence with noise-cancelling activated: keyboard tapping, background chatter and low-level street noise are all sufficiently blocked. Just don’t be expecting such effectiveness in noisier environments: a busy road of traffic continues to be discernible, as are raised voices, hampering quieter songs comparable to Nils Frahm’s My Friend The Forest.

More sophisticated, and pricier, noise-cancellers such because the Bose Noise Cancelling Headphones 700 do a better task in such situations, however for the cash, the Sennheisers are living as much as expectations.


That is most commonly the case with performance, too, the HD 450BTs producing a easy, rich stability that’s stress-free, to not mention easy to listen to. Whether you’re listening to Frahm’s virtuosic piano playing or satisfying some electro funk impulse, their full-bodied and rounded, but nonetheless masses energetic, supply will amiably provide warm piano keys and sizzling synths alike.

Their tonality is slightly skewed against the ground finish, sacrificing the midrange clarity that extra impartial competitors, such because the AKG N60NCs, are in a position to. That would possibly not play into the fingers of each and every music fan, however those who like electric guitars to sound weighty and basslines beefy will to find favour in the Sennheiser’s modest bias. 

Play The Weeknd’s Heartless they usually gobble up the track’s bass drop. Its potent presence isn’t without bass definition and agility either, the beat finding its groove to power the observe ahead.

The accompanying vocal and trebly synths, which sit simply on the peripherary of the Sennheiser’s centre-stage highlight, elevate first rate element and as much impetus too. By comparison, regardless that, the AKGs and in a similar way priced Philips PH805s do greater justice to the manufacturing by surfacing higher texture and dynamic variation.


The Sennheiser HD 450BTs aren’t the most efficient sounding noise-cancelling headphones out there for the cash. Nor are they the perfect to regulate in your head.

But while they are going to lack the outright transparency and ease of some, there actually is lots to love here – now not least in the way in which of top-notch options, such as excellent battery life and aptX Low Latency beef up, which might be a ways from given in headphones of this value. If battery and bass are up there on your record of priorities, you gained’t remorseful about making those Sennheisers yours.
