Review: QuietComfort 35 Headphones Prove Bose Won't Miss the Headphone Jack

With the controversial absence of a headphone jack on the iPhone 7 now a reality, accessory companies are busily churning out wireless alternatives, and that's as true of Bose as it is of other big audio brands.

Its latest QuietComfort 35 over-the-ear headphones ($350) are a wireless version of the company's flagship premium QC25 cans ($300), seen by some as offering the best active noise-canceling in the business.

The QC35's retain the same established design and patented ANC smarts, so as an owner of a pair of original QuietComfort 25 headphones, I was interested to see how the new Bluetooth model compared.

Design and Features


The box that the QC35's come in is reminiscent of the QC25's, and the included compact travel case that the cans fold up into boasts the same assured sturdiness. You get a thinner 1.2 meter lead for wired connections, a micro-USB to USB-A charging cable, and the same airline adapter is also included.

Taking the QC35 cans out though and weighing them against the wired model, it's clear the transition to Bluetooth meant the QC35's had to put on a little weight - 115 grams' worth, to be exact, for a total of 309g. So what brings the added heft?

As you can see from the pictures, cosmetically there's very little difference between the two models. The steel headband has been marginally widened, and the single AAA battery compartment has been replaced by an integrated, non-replaceable battery (rated up to 20 hours in wireless mode and up to 40 when wired), with a micro-USB port for recharging.

Hidden inside the metal-capped ear cups is a dual-microphone system that filters out ambient noise with equal opposing audio waves generated by two proprietary ANC signal processors, which help to pick up your voice during calls, too.

Also new is a dynamic volume-optimized EQ, built-in voice prompts, and a trio of physical controls along the edge of the left can: set between two volume buttons is a larger multi-function button that controls playback, takes and ends calls, and can also initiate Siri with a long press.

The Bluetooth pairing mechanism has been integrated into the original power switch and is activated by sliding and holding the switch until the power LED flashes blue. Wireless range is stated as 33 feet (10 meters), which bore out in subsequent tests.

Equalizers and sound profiles don't feature in the Bose Connect app, presumably because Bose is satisfied that the integrated digital EQ takes care of all that. It leaves the software options extremely basic, limiting you to manage paired devices, select an auto-off timer, update firmware, disable voice prompts, and change language.

Performance


The QC35's paired easily with my iPhone 6s, iPad mini 4, and MacBook Pro, and the only time the connection dropped was when I was listening to music in the kitchen and the microwave was on. The cans had no trouble pairing with two devices and switching dynamically between them, and all my devices were remembered later and re-paired automatically.

The controls felt well placed, if not as intuitive as the QC25's inline remote, and a couple of phone calls were taken while walking along the street, with the new ANC-microphone pairing doing a good job of minimizing ambient noise without detracting from voice clarity during conversation.

Despite the extra weight, the QC35's never felt uncomfortable to wear, even when I did so for long periods. The widened headband seems to be the masterstroke here, offsetting that extra weight equally between the pivots and cups, while undoubtedly being helped by the soft synthetic leather cushioning that surrounds each ear. In terms of comfort, these headphones really are up there with the best.

Audio-wise, the QC35's didn't disappoint either, delivering well-heeled bass and excellent sound separation, especially with instrumental music. They do lose a bit of oomph in the mid-range when listening in wired mode when the ANC is off, but the Bluetooth battery life was long enough for it not to be a significant concern. Plugged into a MacBook Pro, a full charge took about two hours – fine.

The entire listening experience really benefitted from the always-on ANC – effectively silencing the drone of jet engines during a domestic flight, for example – while the low-level hiss characteristic of noise-canceling systems was barely audible, even at low volume. Whether sat in my living room or stood on a sardine-can commute, I was left with the overriding sensation of being pleasantly cocooned in a private bubble of sound.

Bottom Line


I'll miss the QC35's. The cans' interchangeable, dynamic pairing between my iPhone and MacBook quickly became second nature as I switched between devices, leaving my wired QC25's feeling positively passé in comparison. Besides the practicality of Bluetooth though, there's very little between them.

The superior quality of Bose's patented noise canceling is so well established these days that casting judgement on it almost feels redundant. Having said that, I don't consider Bose's ANC untouchable, with similar systems on cans like the Parrot Zik's and Sennheiser PXC-550's now offering almost-as-good if not equal performance in recent tests. I didn't notice any real improvement over the QC25's ANC either, so you could make the case that Bose has stood still while its rivals have caught up.

That's not to take anything away from the QC35's, though. In terms of marrying comfortable sound isolation with quality audio reproduction, they're still the complete package. Does the $50 hike on an already premium-priced set of headphones justify the transition to wireless? Maybe not, but it's less a matter of 'courage' than it is one of convenience.

There are a couple of other caveats. The rechargeable battery isn't replaceable like the Parrot Zik 3.0's (for instance), which could put off some. The powered ANC doesn't work in wired mode when the battery is dead either, but the passive isolation offered by the seal of the ear cups does provide a decent buffer against noisy environments.

Pros
  • Luxuriously comfy over-ear design
  • Excellent battery life
  • Dynamic pairing between two devices
  • Signature active noise-canceling
Cons
  • Threadbare app
  • Lower audio quality in wired mode
  • Non-replaceable battery
  • $50 premium for Bluetooth

How to Buy


The Bose QuietComfort 35 headphones cost $349, are available in black or silver, and can be ordered on the Bose website.

Note: Bose loaned the QC35 headphones to MacRumors for the purposes of this review. No other compensation was received.

Update: The Bose QC35's come with a micro-USB port, not mini-USB, as originally stated in error.

I own a pair of these and they converted me to Bluetooth headphones. The noise cancelling is also excellent.

Why mini-USB? I'm already annoyed that new devices are releasing with micro-USB instead of USB-C charging ports... How many different USB cables/adapters do I need to carry?

So, to charge them you need another different charger. How about Apple paying Bose some money to offset the cost so Bose would offer a Lightning cable/power supply instead of needing a micro USB power supply and cable?

Because they own beats and don't want you buying Bose.

I prefer their in-ear version due to the compact nature for travel (I don't need more weight and bulk on my minimalist travel kit). I'd really like to see a lighting version of those without the battery (i.e. powered by the phone).

Bose just released a very, very awesome software update for the QC35 today. It's so good I just bought a second set of QC35. Music Share. It's awesome. It lets you pair a QC35 to another QC35 and share one person's iPhone or iPad music/audio. And yes, this works for movies etc in Plex, too. So. Awesome.

Seriously loving these phones. Just the peace and quiet when using them is hard to argue...

Anybody know enough about noise cancelling to explain why they can kill engine noise, but not voices? Seems like the random, broadband noise would be a tougher challenge than speech. Is it a deliberate choice?

The headphones have to listen to the surrounding noise, generate a negative version of the current sound waves reaching your ears and then play that inverted sound on top of the ambient sound to cancel it out. There is processing power involved so there is a limit as to how often you can sample the background noise, which effectively equates to the frequency of the background noise you can cancel. The lower the frequency, the more effective the cancellation. Thus low-frequency hums, engine noise etc is cancelled more effectively than higher-frequency speech etc.

I've been reading on the Bose forum that the latest firmware 1.2.9 has caused less quality sound... more compressed, less bass, etc. Has anyone noticed that here?

I've seen these comments on the Bose forum, but I haven't really noticed any sound quality difference (good or bad) with the 1.2.9 firmware update. I have noticed less bluetooth "skipping" however.

Is there any lag or delay in audio on video playback?

I had a pair of bluetooth headphones a while back and remember getting rid of them because of the delay with video playback. Hoping they fixed that issue by now.

I've watched things on Netflix, Hulu, YouTube, and various other places, and I have yet to notice any lag or delay in audio playback.
