Bose QuietComfort 45 Review — A slightly aging classic holds its ground against newer models by perfectly executing the fundamentals of comfort and noise cancellation

Bose's older QC45 headphones might actually be a smarter buy than their brand-new replacements. While the industry chases the next "revolutionary" feature, Bose quietly perfected the fundamentals, leaving the QC45 as a masterclass in why utility often beats innovation.

What you're actually getting

If you’ve spent any time in a cramped airplane seat or a noisy open-plan office, you know that the "perfect" headphone isn't the one with the most features—it’s the one you forget you’re wearing. The QC45 is exactly that. It doesn't try to be a fashion statement or a high-fidelity studio monitor. Instead, it’s a tool designed to make your environment disappear. As CNET noted, "The QC45 is arguably the most comfortable pair of over-ear headphones out there," and after wearing them for a year, I’m inclined to agree. They are light, the clamping force is perfectly calibrated, and the ear pads don't turn your head into a swamp after two hours.

However, you have to accept the "Bose tax" on materials. These feel undeniably plasticky. If you’re coming from a pair of metal-heavy Sony or Apple cans, the QC45 will feel like a toy. But there’s a functional genius to that weight—or lack thereof. Because they are so light, you can wear them for an entire trans-Atlantic flight without that dreaded pressure point on the crown of your head.

You aren't buying these for audiophile-grade critical listening. You’re buying them because they work every single time you put them on. There are no finicky touch controls to misfire when you’re adjusting your glasses, and the multi-point Bluetooth connectivity is rock-solid. As Mark Ellis Reviews put it, "They are the best jack of all trades, and I mean that as a massive compliment." They aren't trying to win a spec war; they’re trying to win your commute.

Sound — what reviewers actually heard

The sound profile is a classic Bose "V-shape" that’s been slightly cleaned up. It’s punchy, energetic, and forgiving, which makes it great for podcasts, pop, and long listening sessions where you don't want to be fatigued by harsh treble.

• The Midrange: Vocals are clear and forward, making them excellent for conference calls and spoken-word content.
• The Bass: It’s boosted, but not muddy. It provides a nice foundation for electronic music without bleeding into the mids.
• The Highs: They are rolled off. You won't get that "sparkle" or micro-detail you'd find in a pair of open-back Sennheisers, but you also won't get the sibilance that ruins long sessions.

Where it actually wins

The noise cancellation is the star of the show. It’s not just about the decibels blocked; it’s about the consistency. The QC45 handles low-frequency drone—like airplane engines or HVAC hum—better than almost anything else in its class. It creates a vacuum-like silence that is genuinely impressive.

The physical button layout is another massive win. In an era where every manufacturer is forcing us to use erratic touch-capacitive panels, Bose stuck to tactile, clicky buttons. You know exactly when you’ve paused your music or skipped a track. It’s a small detail, but when you’re fumbling for controls in the dark or while wearing a hoodie, you’ll appreciate the reliability.

Finally, the portability is unmatched. The hinge design allows them to fold into a compact, sturdy case that barely takes up any room in a backpack. If you travel for work, this is the single most important feature you can have.

Where it falls short

The lack of high-res Bluetooth codecs is a glaring oversight for a pair of headphones at this price point. If you’re an Android user who relies on aptX or LDAC for higher-bitrate streaming, you’re stuck with standard AAC/SBC. It’s not a dealbreaker for Spotify or YouTube, but it feels outdated in 2024.

The software experience is also a bit rigid. You cannot turn off the ANC entirely; you are forced to choose between "Quiet" (ANC on) and "Aware" (Transparency mode). Sometimes you just want the headphones to be headphones without the DSP processing, but Bose won't let you. Furthermore, the lack of wear detection—meaning the music doesn't automatically pause when you take them off—feels like a missed opportunity for a device that is otherwise so well-thought-out.

Should you buy it?

Buy if you:

• Are a frequent traveler who needs the best possible noise cancellation.
• Prioritize comfort above all else for 4+ hour listening sessions.
• Prefer physical buttons over unreliable touch controls.
• Want a reliable, compact, and proven workhorse.

Skip if you:

• Are an audiophile looking for high-res codec support and critical detail.
• Need modern "smart" features like auto-pause/wear detection.
• Already own the QC35 II and are looking for a massive leap in performance.

The Bose QC45s are the ultimate travel companions thanks to unmatched comfort and top-tier ANC.
