Bose made its name in the wireless headphone dissonance cancelling market with its QuietComfort series, simply it’s been a number of years since the last iteration.

In the years since, Sony has emerged equally the peak dog in the noise cancelling headphone market, trading blows with Bose with each successive pair.

Given the corporeality of Bose headphones still being used by people on their commute, the series remains a pop one, but arguably Sony has replaced them atop the mountain with their WH-1000X series. So what does Bose accept to offer in response with the QuietComfort 45?


  • Updated design
  • Very comfortable to wear
  • New USB-C charging port

From an aesthetic standpoint, the QuietComfort 35 II were fairly ordinary looking pair of headphones. The QuietComfort 45 are evolution over revolution, so while they retain the same profile as their predecessors, the pattern updates give them a modern expect.

They’re non as sleek and minimalist as Bose’s own NC Headphones 700, the impression they give is that these are the workhouse of Bose’s headphone range. The changes range from the removal of the pleats and pluckers, with synthetic leather used for the earcups besides as the underside of the headband.

Bose QuietComfort 45 headband

The headband structure has been reinforced with drinking glass-filled nylon to help maintain its shape and baby-sit against whatsoever falls. The cloth that covers the headband attracts smudges, especially if yous purchase the White Fume model over the Triple Blackness version.

Speaking of colours, it’s more than likely Bose will release more once the QuietComfort 45 take been on the market for a while, like it does with all its headphones.

Aesthetically it carries a more than elegant, refined wait. The matte pattern makes for a more cohesive look than the metal sheen of the older models, the transitions between the hinge, headband and ear cup are smoother, and at 240g the QuietComfort 45 are very comfortable to wear. Once on yous’ll barely notice their presence.

The left earcup features the button for switching betwixt the racket cancelling modes, and on the correct are the playback/volume buttons and the switch for turning the headphones on and off. All are easy to reach, and with the slight gap in-betwixt each playback button, mistakes are few and far between in terms of operation. You still get a 3.5mm jack, while the USB port has been upgraded to USB-C.

The pattern is still collapsible for folding them up or you could choose to put them in the carry case to save them from whatsoever nicks or dirt. The changes to QuietComfort 45 aren’t massive, just they are successful, keeping the same iconic expect merely giving them a modern aesthetic in the procedure.


  • 24 hours of battery life
  • Spartan characteristic ready
  • Excellent dissonance cancellation

Bose never seems concerned with matching the battery life of rivals. Whether it’s the QuietComfort Earbuds or Noise Cancelling Headphones 700, battery life has been around the twenty 60 minutes mark. The QuietComfort get a boost but they won’t trouble the likes of Bowers & Wilkins, Philips or Sony, but information technology does at to the lowest degree hateful they tin be used for longer.

With fast-charging via the new USB-C port, you lot can peak of the battery life quicker if you need more time, a 15-minute nuance offers three more than hours. A full recharge takes two-and-a-half.

Wireless connectivity is Bluetooth 5.1, and in terms of stability the connectedness has been first-class. I’ve sailed through Waterloo, Victoria and London Span railroad train stations with barely a hint of a intermission-upwards.

Multi-point back up means the headphones can exist paired with ii devices at once, a flick of the switch on the right ear-cup jumping to a previously connected device. With Bose’s SimpleSync technology embedded, the QC 45 have synergy with other Bose speakers and soundbars for a private listening session.

Viewed in the context of recent headphone releases, the QC 45’due south range of features is surprisingly depression. Compared to the previous model information technology’s around the same so they’re not an improvement. If you’re looking for a Bose headphone with smarts, the Noise Cancelling Headphones 700 are the better choice and that may annoy some.

Bose Music App QC 45

Perhaps that’southward deliberate on Bose’s part to differentiate the two. And then, while the headphones are compatible with the Bose Music app, information technology’due south a rather sparse for features with no built-in vocalism assistance (y’all tin engage your mobile device’s digital banana by holding the playback button); no equaliser settings, no range of racket cancellation levels to cull from and no shortcuts. However, updates down the line could bring more features to the party.

Even article of clothing sensor technology is missing, and so music won’t auto-stop or play when you take the headphones on and off. All of this gives the QC 45 a very transmission feel in terms of operation, and perchance that makes for a more tactile, less complicated feel. If you’re someone for whom smarts have entreatment and then the Bose QC45 aren’t and so clever.

All the same, where the QuietComfort 45 practise non disappoint is in their noise cancelling functioning. Well, they do slightly disappoint in simply offering 2 modes: Quiet and Aware, which ways ANC is either full blast or filtering the outside world through to your ears.

Using microphones inside and outside of the earcups, and a proprietary algorithm to detect sounds (with a particular focus on midrange frequencies), the noise cancellation lives up to the QuietComfort legacy.

The world around the wearer becomes impressively and eerily quiet at times, and given how thoroughly the headphones can remove noises, it means in that location’s niggling need to raise the volume to hear your music. Even at mid book levels their noise cancelling functioning dispels sounds with virtually nonchalant ease.

Vehicles are reduced to mere hums passing by. The hubbub of transport terminals is nullified very effectively, while journeys on trains only pass by with piffling interruption, the bumps, knocks and sound of the wind rushing by cancelled out with conviction.

The QC 45’s faculty with diminishing voices is impressive, when using the headphones at Borough nutrient market, nearby conversations were reduced with such an effect that at times that it looks every bit if people were wordlessly moving their mouths rather talking to each other. Wearing them surrounded past people at Waterloo station and there was a moment where I’ve never felt quite as isolated from what’south around me.

When faced with wind, they remain good, though similar any ANC headphone, blustery atmospheric condition tin knock them off their stride. I also noticed that jolts from when a train door closes can also affect the noise cancelling for a brief but jarring moment.

A switch to the Aware mode and the sound of the globe pours in with clarity and particular. Waiting at a nutrient market, I didn’t need to take these headphones off to hear my order being called out, and in general y’all can go a sense of what’due south around y’all, though these headphones won’t quite give your ‘ears’ in the back of your caput with regards to what’southward behind you lot.

Are they improve than the Sony WH-1000XM4? In some ways yep, in others the Sony may just take the edge. Simply there’s no doubting how formidable the performance of the QC45 is. They may exist the most effective dissonance cancellers on the market.


  • Neutral, clinical tone
  • Smashing levels of detail and sharpness
  • Can struggle describing more busy tracks
  • No aptX

The QC 45’due south sound is much in-keeping with the NC 700 HP, and as such they’re a make clean, detailed and precipitous presentation. Compare them to the Sony WH-1000XM4 or Philips Fidelio L3, and they’re not equally musical.

Simply the QuietComforts are strong in a range of areas. Bose’s Active EQ serves to attune the performance regardless of volume level, and their sense of dynamism is fleshed out well with a singled-out deviation in communicating the highs and lows of a track.

They perform well towards the height end of the frequency range, their sharp tone giving treble notes sparkle and effulgence in Raven’southward GoGo Penguin. They’re a punchy performer, bass defined with a tautness, reined in rather than allow loose but still enough to have touch on.

It’s with vocals where the Bose aren’t equally good as their rivals. Departing Ways from the Soul soundtrack lacks the focus of the Sony rivals, the lyrics rendered with a chilly tone that’southward as well present in Faye Webster’s Sometimes. Information technology’s a more clinical, neutral tone and while that peradventure treats voices with more than consistency only robs of emotion – an area where the Sony headphones excel.

Bose QuietComfort 45 laid flat

Feed them a simple track, similar John Powell’south The Bedroom, and the clarity, sharpness and detail of the guitar strums are splendid. You can hear every pluck of the guitar, every difference in the notes. The instruments in Robert Glasper’southward London are naturally conveyed, with the Bose displaying a weightiness and sense of precision to the percussion that thoroughly engages.

The Bose QuietComfort 45’due south presentation is clean, spacious, detailed and sharp but they tin can as well audio clinical and a piddling brittle in tone. They can sound very expert but there are more subtle and thrilling headphones to choose from in this competitive market. If sound is
priority, the Bose fall brusque of the best.

If sound is the priority

Last Thoughts

As an update to the QuietComfort series of headphones, the Bose QC45 fulfil their goal. Condolement is excellent and the noise cancelling impresses. If yous own an older pair of QuietComforts and and are looking to upgrade then you tin upgrade with confidence. In terms of audio there are better options available, and in terms of features they are surprisingly sparse for their premium cost.
