Hopefully will help keep his ears safe.

the same right ear problem everyone was complaining about.

Very comfortable, noise canceling is fantastic, but sound in right ear cuts in and out

The headphones produce good sound but after light use, the right ear stopped working

After 30 months of very light use and very good care, the right ear cup suddenly stopped working.

I will update in a couple of months to see if the right ear brreaks.

A pair of well-made headphones with good ear isolation will do the job close to those ones in noise canceling and you will get a better music quality.

He’s hard of hearing, the typical earbuds hurt his ears

I tried pushing the connector more firmly and tapped on the faulty ear, but all to no avail.

Left ear stopped working 2 weeks after the warranty expired.

Suddenly I began hearing scratchiness in the right ear, as though there were a dirty connection or a bad cable

This is probably the best purchase i have made as they allowed me to sleep like a baby in a 16 hour long flight and cut off the sound of engine, crying babies and people talking.biggest problem with most closed headphones is that ears get hot and sweaty but not with Bose QC25Sound:The sound signature has improved a lot but still lack the punch when listening to rock music

Brilliant! saved my ears and my nerves

At times reinserting the plug would work, and music was audible through the right ear, however, there was a lot of maneuvering and holding of the cord to be done

Definitely good performance from the product and customer service ended up resolving the problem, although it took a couple of calls.******These worked fine for about a year and a half, but then the right ear started to fail.

Right ear cutting in and out

I love them, mainly because they're big enough and they fit over my ears, and I know this might sound crazy but my ears do not get hot when I'm wearing them on long flights

After a few more than 12 months the right ear muff died

I can still hear a little bit of surrounding noise while at the gym, but I never crank the volume way up, plus considering I used plain old cheap ear buds for

I (stupidly) thought I was imagining it, until a particularly loud landing resulting in a repeated popping sound in the right ear, with the noise canceling dropping out intermittently every use after that

Unfortunately the left ear cup failed after 364

During the winter these kept my ears warm on my walks

The right ear cup suddenly stopped working.

The right ear stopped working after only 18 months

This is absolutely unacceptable given that nearly all the one star reviews state the exact same problem that the right ear fails within months usually right at the end of the warranty and Bose refuses to fix it

Bucause of the loose Jack connection the sound only works in the right ear then the left ear then both then no sound at all you must constantly move the Jack connection to receive proper sound I tried two sets to make sure factory defect

(I love prime now thanks Amazon) and these headphoens worked great until the right ear stopped working

My ears have yet to hurt yet!Cons:- the battery cover scares me

So many people are complaining about the defective right ear, some even discovered it a little over the warranty period

But ear feels uncomfortable when wearing it for too long.

Good sound, top 5 in noise-cancelling headphone options, user replaceable battery (AAA) with long life, user replaceable ear-pads, lightweight, comfortable fit, close-out pricing, nice case included, works well for a big head like mine, ears don't get too warm after wearing them for a long time, can use the NC feature even without music

There was a spotty connection and if the cable was touched during use the sound to the right ear would cut out

It sounds silly, but the covers and noise cancelling causes my ears to get sometimes uncomfortably warm.-The noise cancelling is designed for aeroplane noises.

Doesn't hurt my ears, plays my jams clearly, and can block out my haters.

My ears don't hurt after several hours of waring them, unlike other non noise reduction earphones

The noise cancelling and EQ features are controlled by a switch on the right ear

My ears are sensitive to the fit of headphones, but these are very comfortable and nicely padded

I really liked these headphones but as many listed on here after 2 years the right ear stopped working and Bose did nothing

When I first received these, the right ear didn't work

When I first received these, the right ear didn't work

Basically left with a very expensive pair of ear-warmers.

Was very happy with these headphones for ~5 months until I lost all audio and noise cancelling in the left ear (apparently this is a relatively common problem).Bose agreed to replace the headphones, but I have to pay to have them shipped to them

The first pair gave way (left ear cup stopped functioning in 4 months), got it replaced by Bose and then the second one had the same issue in the right ear cup in around 7 months

There was no sound coming from the right ear

I have sensitive ears, when I try to turn on the noise cancelling my ear drums feel a constant pressure.

Just a bit annoying at first, but then it was unbearable noise every time I touched the right ear

Great for flying able to hear movies & music well but they hurt my ears after awhile of wearing.

That said, there's a decided difference between choosing an over-ear set and an in-ear one -- and, as much as I love these, I'm not sure I made the right choice.

I'm not sure if it's the cable that came with the headphones or the headphones themselves, but if the cable budges even just a tad, the sound stops coming out of the right ear

Alas as soon as we took the device out of the box and plugged in, we could not hear anything from the right ear

If i move my head I lose sound in the right ear

later I lose the right ear mid-flight.

If these babies are not snug around your ears or if you have music playing others around you will hear it.-Battery dies quickly-Not the best headphones for working out in... or walking around in... unaesthetic and clumpy in my opinionBOSE give me free ear cushions

Right ear quit working after 19 months.

The right ear cup's sound gave out randomly both times

And then the right ear stopped working altogether

They sound fantastic when they work and the noise cancelation is amazing but constantly losing sound in the right ear is obnoxious

Comfortable, if a bit warm, for extended periods - but this means they double as great ear warmers in the winter

Typically, noise canceling headphones hurt my ears when I wear them for a long time, but these were so comfortable I was able to wear them for the entire flight

The only reason I didn't give them 5 stars is that, as some others have mentioned, there's intermittent loss of sound in the right ear, but I've been able to manage by jiggling the plug

After a few more than 12 months the right ear muff died

Not reliable and right ear stopped noise cancelling and producing sound

I just opened it and the right ear does not produce any sound

Really hugs the ear in a comfortable manner and truly, cancels everything out around you

Incredibly comfortable ear cups that offer hours of enjoyment.

Definitely good performance from the product and customer service ended up resolving the problem, although it took a couple of calls.******These worked fine for about a year and a half, but then the right ear started to fail.

Later, on 8/11/15, yet again I was forced to exchange them for a new set for the same problem (right ear just went dead).

However I've had two pairs break where one ear stops working, hence the one star.

,THERE WAS NO AUDIO FROM THE RIGHT EAR!!!!!!!

(I don't remember for sure which ear, but I'm pretty sure it was the right ear).

Bose makes an in-ear noise cancelling set (QC20) that I was considering before I bought these, and I now wonder if they would have been better for me since in-ear doesn't bug me the way that it does other people.

Left ear stopped working 2 weeks after the warranty expired.

I used them while flying and maybe got 15 uses out of them before the right ear died

All of the different items I've tried worked for me to some extent, but the on-ear Sony item would start to irritate my ears after an hour or so and didn't provide any real noise abatement after the battery died.

There are white noise generators but they just add audio noise "load" and my ears were fatigued by the end of the day

Unfortunately, the only problem is that it doesn't breathe well, so your ears will get hot & sweaty with extended use.

Bose is unparalleled in noise cancellation technology -- my Sennheisers were good, but not this effective -- and, as a result, I turned these on without sound for a couple of hours just to protect my ears

The brand must know that the spectrum have the most sensitive and keenest ears, it’s about buying a product that delivers the most needed noise cancellation and sensory fit comfort.

With these, I got to enjoy my music and not kill my ears.

My significant other also likes to wear them when mowing the lawn because they help to protect his ears AND he is able to actually hear the music that is playing.

The noise cancelling is fantastic - better than my Panasonic’s - but there is no sound in the right ear for movies or gaming

The right ear phone didn't work, and when I connected them to my iphone and my mac, the connections were not good--on and off.

I have only had these headphones 3 months and the right ear stopped working

the same right ear problem everyone was complaining about.

Now in July 2018 the left ear on my headphones fails again.

1 month after the warranty expired (July 2017) the left ear died.

Now the bad: approximately 11 months after purchase, my headphones started to lose noise canceling in the right ear

So many people are complaining about the defective right ear, some even discovered it a little over the warranty period

However 16 months into the life of (with minimal use, 10 hours/month at most), the noise cancelling stopped working in the left ear

the stitching that holds the leather padding together on the right ear piece has come undone

After about 6 months one ear stopped working

Maybe three months ago (after being very happy with the product) the right ear started to get a little fuzzy

I've worn them in the rain and snow (they work as pretty good earmuffs), dropped them on concrete more times than I care to admit, and they once even protected my ears from a snapping coil of barbed wire trying to impale my ear

The right ear piece stopped producing sound after only 6 uses

Googled info about NC and found out not everyone can use NC due to sensitive ears

I use these for sleeping and when it is just to noisy for my sensitive ears!

But customers should know that, unless you treat these headphones very delicately or not at all, some issue with the right ear may come up.

right ear lost sound

Great great sound, fits your ears nice and comftable

Last year I did try an inexpensive pair of over ear headphones and they hurt my ears

The fake leather finish is also worn out in about 30% of the surface of the right ear, and about 10% of the surface of the left

With a light smack while wearing them on, you can hear some cracking noise coming from the right ear

The other ear is dead.

The noise canceling is great, but I couldn't tolerate the hot ears.

Many of these have a known defect: the right ear stops working

The only positive note is, like other reviews have stated, the noise cancelling function did perform well and the audio quality was good when you could get sound out of both the left and right ear.

Unfortunately, a month into having the replacement pair, I'm noticing the same issue where audio to the right ear will cut out if I move the cable

Granted, there are better sounding headphones, at similar price points than these, but the reason you purchase these headphones is for the noise cancellation, not critical audiophile reviews and golden ear listening

The right ear stopped functioning after two weeks.

I used these for the first time on my flight to Texas on October 30, 2016 they killed my ears really bad

But after 1 and a half years of use with great care, the right ear cup finally quit working -- no audio, no noise canceling

Granted, there are better sounding headphones, at similar price points than these, but the reason you purchase these headphones is for the noise cancellation, not critical audiophile reviews and golden ear listening

Where the QC25 really shines, however, is when you flip that little switch on your right ear.

Right ear stops working after becoming filled with static

Bonus - keeps your ears warm too!

These are not soundproof headphones or ear protection.

These work really well, but they hurt my ears after a half-hour or so.

Purchased these in Feb 2015 and the right ear piece just stopped working.

Don't be surprised when it hits you.-Warm ears.

Right out of the box I noticed that the right ear was not getting any sound

My ears are sensitive especially to low frequencies

And the fact that these encase my ears (rather than lay on top) makes their effectiveness even better

When turned on only the right ear-piece would go 'deaf' while the left one stayed the same

Right ear cup developed static sound even when not plugged into a device.

They are great, however the right ear pad is pretty loose

There's a design flaw in which the hinge of the right ear causes the wire to disconnect, apparently from the act of bending and unbending the phones to fit in the case

The audio and noise canceling for the right ear stopped working in May 2017, after extremely light use (in a very clean environment) during that period of time

When listening to the music, I heard some sounds and tones in the detail I never head before, and I have very sensitive ears

Sound was lost in one ear first and then both ears.

The headset continually dropped out in the right ear and sometimes the right ear

I'm constantly having to fiddle with the jack bc the right ear drops out

I owned them for about 18 months before the sound cut out in the right ear

Someone who has perfect pitch and a keen musical ear says that these are not the best in terms of High fidelity, but for my unexperienced ear they are quite alright.

The right ear cup lost its sound after about 22 months

I was very happy with the performance of my headphones, but one of the speakers/drivers failed a shortly after my warranty ended

It apparently works as he has to tap her on the shoulder to get her attention... when he's sitting right next to her!

I also use these for gaming at home as well as on the airplane whenever I travel

Love them for noise cancelling as well as for phone calls

I frequently go on two-hour car rides with my family and the noise canceling really blocks out noise in the car as well as on airplanes

The movies are where bose really shine as they deliver very clear stereo separation and vocals

After about 10 minutes, I tried again and alas, L started working and R was dead

However, now the R ear no longer works

Verified again and L was active and R was dead
