Other than the terrible battery life, I highly rate the headphones for comfort and superb noise cancelling

Impressive battery life, lasted an entire 17.5 hour flight with life left

Now, they use an internal, non-replaceable lithium ion battery.

Great sound, super battery life, comfortable, noise cancelling is very effective

Impressive battery life, solid bluetooth connection for two devices, expensive but not THAT expensive

Battery is good.

Great sound, better range than all my other bluetooth headphones, near instant pairing, unreal battery life, best noise cancelling

Very good battery life.

Charges fast and has great battery life

So far, the battery has performed well too - despite taking these headphones to some really cold places (up to -8 deg C)!

Despite these minor flaws, there are plenty of good things, like a great carrying case, amazing battery life, good range, quick charge time, can connect to multiple devices at once, and have amazing noise cancelling (which you’d expect)

They're wireless, they have a great battery life, they're comfortable and the sound quality is great

Very comfortable and great battery life

Great battery life so

Still not sure I like the idea of a proprietary battery, as it was easy to just carry AAAs around when you were going on a trip, but it works very well, sound insulation

Superior battery life, more lively sound, great equalizer customization in the app, touch controls and LDAC support

Mute button, replaceable battery, 2.4Ghz in addition to Bluetooth, good audio quality while using mic

Replaceable batteries as the last model had are preferable.

This, of course, means the battery will now burn out much faster

However, on a full charge the battery lasts a long time and it will work when the battery is dead on a head phone jack

It's unfortunate as this device has a lot of positives (good battery, great sound, easy to use, nice carrying case and compact fold pattern) but none of them matter if the device doesn't work

I do miss having replaceable batteries.

I get good battery life from them

Other top end active noise cancelling headphones offer a replaceable battery (e.g., Beoplay H9).

Amazing sound, comfortable, and great battery life

Which leads me to the last issue, the battery

I have unpair, rebooted device, drained the headset battery, reloaded the Bose App, resynch to my phone many times, airplane mode, turned off bluetooth, tried on different phones, computers tablets, ... in the end, it all fails

Sony has longer battery life (but both have great battery life)

This does seem to help my ear pressure ache now the battery is messed up

I find that the rechargeable battery is not as convenient as a replaceable battery.

It is too soon to tell if it has a defective battery.

Even when the on/off switch is in the off position, the headphones will turn on automatically, draining the battery unnecessarily

On a very long international flight, with connections, the battery is gone and recharging is not as easy as replacing the battery.

I do miss having replaceable batteries.

However, on a full charge the battery lasts a long time and it will work when the battery is dead on a head phone jack

Awesome battery life and everything sounds amazing

It comes with an 1/8" cable that will allow you to listen to music even when the batteries are dead.

Nice feature of audible battery status when connecting to devices.

Amazing battery life

Comfortable, good battery life

Bought these for my wife, she loves these and the quiet they give her while doing her meditations, very comfortable and good battery life.

The only complaint would be the battery

Wish they looked a little betterNon user replaceable battery

Battery is great

I currently work on a golf course and operate large mowers and they have great sound, great noise cancellation, and very good battery life

and I'm sure the other constraints on closed-back wireless noise-canceling headphones with great battery life make it difficult to achieve sound like other headphones at the same price

Very good battery life

Bring back the AAAs of the QC15 and old QC35.Am returning this and going back to my QC15 until someone makes a decent set of cans with replaceable batteries.

Battery power, outstanding

Now if this was something built into the product like what you can do with a Tesla car, that would be really nice as changing out batteries every two years or so, especially with how devices are built these days is a bit of a PITA and too often

Stellar connection quality, wonderful comfort, and a surprisingly-great battery life

Battery life if outstanding.

It will turn on at random times and the battery gets drained.

v1.The only reason it loses a star is a non user replaceable battery

Great battery life and quick charging.

These are really great headphones, they sound awesome, the noise cancelling works great and hey have excellent battery life

Wish the QC35 had AAA or replaceable batteries

And an impressive battery life.

Great battery life.

WITH THAT SAID, leaving it on will drain it regardless, so make sure to flip that switch and shut them off or how awesome the battery is, isn't going to matter

Good battery life between charges.

Pros: - Comfortable - Long Battery Life, I have used them for several hours over several days without needing to recharge them - Great sound.

Great battery life, incredible sound quality

Great battery life

If all you want is great sound and good battery life please go else.

the best.+ great battery life+ nice fold up design fits anywhere+ excellent sound

These headphones have a good battery life, but the most important thing is COMFORT

Pros: Great noise reduction, pretty good sound quality,great battery life

Some prefer removable AA/AAA batteries, but to me it's not a deal breaker.

The internal battery is a positive step and battery life is good

The good:Love the noise cancelling (in my own ears), and they’ve got terrific battery life.

On a 14 hour flight plus connections, the battery dies on the QC35 and it is a pain to recharge whereas swapping a battery is trivial.

Doesn't turn off properly and battery is drained

On the downside, it doesn't have a replaceable battery, and as Bose things tend to last a long time, I suspect it will out last the battery, so I will cross that bridge when I get there

so I was very skeptical of the QC35s non-replaceable internal battery, but it really hasn't been a problem thus far

Great sound quality, Great battery life

>QCII is the most comfortable b/c it's light, little clamping pressure, and good headband cushion

Comfort: Pretty good (B+), enough to last 10 hour flight with just occasional

Why not the VMODAs? - uncomfortable clamping force, but great foldable compact headphones w a good detailed soundWhy not the B&W P9? - not foldable and has clamping force around earcups, but love the sound (by far the best amongst wireless headphones), love the premium material (feels worth the price tag), and small ear cups (so doesn't look bulky but sleek, although ear cups were uncomfortable)Why not BO H9? - not foldable/travel -friendly, not much else that stands out over others

As far as sound quality goes, the soundscape is nowhere near as rich as the B&Ws; there's something insubstantial about the sound coming from the Bose.

Got confused couple of times which device is being connected to, but overall it supports two devices best as from my experience with other devices.

Yes, that's as lovely as you are imagining it is, lol.

They feel cheap and come with a very poor quality assecory cord and recharging (it's about 4 inches long an so difficult to reach a charger)

I use it regularly for taking phone calls in a noisy, open plan office environment as well as for traveling on planes

The noise reduction with Sony was nearly as good as with using hearing protection ear plugs

Extremely disappointed as I was excited for the Bose Q35 II.

Own multiple DAC's all the way up to $2000 devices, multiple $500+ headphones which I used to compare these headphones against streaming both Spotify as well as

I really wanted to love these - as I had wanted to when I purchased a pair of original QC35s

Headphones looked new, no wear/tear or markings, and everything worked as it should, so I kept the headphones and had some of the price refunded

Soft as

Oh an not really durable for someone who is not going to treat their headset like newborn baby

Noise cancelling is amazing, I preset the button to noise cancelling levels as I use the other phone brand.

n’t vouch for the NC of the mic

n’t go wrong with these.

For the first time on Bose and on Amazon, I DON’T recommend this product.

n’t see myself taking phone calls or using Google/Siri a lot but for basic headphones basically I love these things

n’t get very loud

n’t lose your situational awareness
