How are these in noise isolation?

Pretty good. I don't hear the background music at the gym or the cardio machine noise.

They are amazing with sound and noise isolation. To top it off they are very comfortable.

Haven't used them on a flight, but they'd probably be decent though they don't have any type of active noise suppression. While they do come with foam isolation tips, I use Comply isolation tips that seem to provide more privacy - they're another 20 bucks for 3 pair, but worth it IMO.

Look at the graph in the upper right in the link below. It is labeled "isolation." There is little noise isolation in the lower frequency range (bass), but very good noise isolation in the higher frequency ranges (midrange and treble). http://www.innerfidelity.com/images/Monoprice8323.pdf

Not sure I understand what you mean by noise isolating. They do not prevent you from hearing ambient sounds. You can hear people talking to you, etc. I haven't used them in my car enough to know if you can hear emergency sirens, but I expect you can.

I would say they block about 90% of outside noise. However when listening to it loud people next to you will hear your music. For the money you can't beat these headphones.

These are provide excellent noise isolation. I have used them to dj in loud nightclubs many times.

Isolating? Yes. Canceling? No. If you get a good fit, they block a lot of the ambient noise but as others have mentioned they do not block out everything. I've used them in airliners and they help. Not as good as the expensive noise canceling buds but they do help. JLab sells replacement silicone tips that have an additional flange which may improve the fit and thus the isolation.

They are very good for drowning out ambient noise, hums, rumbles, buzzes, etc. They are not really supposed to drown out irregular noises, like speech or loud music. I find they do make what I am listening to stand out from the back more sharply, and deaden pretty nearly all external sounds somewhat.They are also well padded, which keeps other sounds out even when you don't have the headphones switched on.

The other people who answered obviously know nothing about the product. It says on the Sennheiser website they have "up to 26 dB noise suppression". (http://en-us.sennheiser.com/earphones-high-end-hifi-stereo-passive-noise-reduction-ie-80)They have very, very good noise reduction. I can hardly hear anything other than whatever music I'm listening to or whatever game I'm playing with these in.

I have used these many times on airplanes. They block out a significant amount of the noise. I put on soft music at a very low volume and sleep soundly...or just turn on the noise cancellation circuitry and block out the constant whoosh of the aircraft flying through the air. I gave a pair to one of my sons who travels a lot and he now swears by them.

The noise isolation is good actually, it's on par with an over the ear headphone. Compared to over the ear headphones these aren't as comfy but it it could vary from ear shapes. The head band is extremely comfy the only place iv'e felt some pressure would be from the cups but i do wear them for hours and i usually keep the fit snug.

The noise isolation is very good but not perfect, and they come with a very nice carry pouch. Their quality is superb, especially if you want good bass.

These have noise isolation padding so when you have it at certain volume you can barely hear outside noise. Even on some lower volume or no volume you can tell the difference. I can hear others talking with them on no sound but it's almost as if they are surpresed

My husband used them ...he didn't have any issues with them and they are pretty quiet .

They are actually noise-isolating, but they work wonderfully at maintaining the clarity of the music and keeping the sound of your surroundings out.

If the noise is in low to mid frequency range then these work well. You will still hear high frequencies but muted some.

Yes, they will leak noise. These are semi-open headphones so isolation is not going to be very good
