Are these (used with no music) better at voice cancellation in a busy office compared to some good passive earmuffs like 3M Peltor Optime 105 ?

In-ear plugs would be best in this case. Neither earmuffs nor noise canceling headphones are designed to work in the speech frequency range.

Wouldn't know. I've never tried earmuffs. On an airline flight to was fabulous in cancelling the engine hum that is ever-present.

I don't know about the Peltor's, but I also have a pair of Bose noise cancelling earmuffs, and these work just as well. I often use them on planes all by themselves to cancel the airplane noise.

I can't compare the QC20 with the passive earmuffs you mentioned. I can say though that the QC20 does reduce the amplitude of voices but maybe not as much as you may want. I do use them in my office while listening to soft music. People have to shake me to get my attention. You can try them risk free for 30 (90?) days.

It doesn't totally block out all sounds, but it does mute it greatly enough that you can get work done. I use these for work also, in a very noisy office.

Without sound, you may hear a "shell ocean" effect that is clearly audible because the seal is not perfect (at least for me). With sound on at even a moderate level, I'm not able to hear people talking loudly, even if they're nearby. But no, they are not noise cancelling. They isolate somewhat but more like good ear muffs.

Absolutely. Best background noise blocker I've ever had. Blocks out work noise, my four year old and my new puppy. I can even use them when i vacume and hear the music over the vacume. I actually have to turn them down when i ride my bike because i can't hear cars comming up on me. Hope that helped :)

I have never had a problem distinguishing voices with the noise cancelation on. The filter blocks ambient sound and greatly reduces the human voice, but you can still tell someone is talking no problem, though you might not be able to hear what is being said. Of course, if you blast your music through these, you probably won't hear a thing, but doesn't that apply to all headphones?

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

They arent noise canceling but the ear cups do a good job of blocking out background noise. I've only used these in an office environment and they did well blocking out some ambient and background noise but again they do not have NC technology.

IMO they cancel noise decently. I use them at home, on my desktop pc, while the tv is on. My TV is about 5 feet away from my pc. I bought them more because they were for my son and halfway durable and has a decent range of size adjustments.

haven't tried that yet, but while working out, and it gets pretty noisy, I can't here the other machines while I'm listening, so I'd rate them about an 8 on noise cancelling. I'm thinking they would do just fine.

There's no active noise cancellation or isolation, so there is some leakage. However, it is over the ear and fits snugly and the noise leakage is minimal -- when I play music at comfortable levels (for me) in the office, my officemates are not bothered. As for isolation, I haven't tried them outside of an office setting though my guess is that these cans may not suffice for a noisy metro ride -- though they do cancel enough noise such that my officemates have to talk at an elevated voice to get my attention/oftentimes I don't hear someone come in the door.

Sure. These are essentially earplugs with built-in headphones. If you don't listen to anything, they still block noise effectively.

These are not *ACTIVE* noise cancelling headphones, but they do a pretty good job of blocking out ambient noise as long as you don't rest your head against the wall of the plane (window seat). [In that case the direct physical sound conduction is noticeable]. I use them on airplanes and I can run my audio volume at half and listen quite comfortably. By comparison, my ear buds require nearly full-blast volume on a plane and the audio still isn't clear.

They reduce some of the background noise but not all of it. They are best at reducing regular noises like the hum from air conditioning or air-plane noise. I got them to try and reduce noise from people talking in my office but it didn't really help with that.

These do not have active noise cancelling (which would need power). Instead they have passive sound insulation. They are quite effective. I use mine for mowing the lawn and can listen to music or audio books without turning up the volume much at all.

No. I use them at the office because of the number of computers running near me, with noisy fans etc. I can hear other people perfectly well when they talk. The headphones analyse the noise around them then generate anti-noise to cancel it out, but it's not perfect ( which is deliberate ), there's a delay in the analysis. Therefore something constant like a fan whirrin will be cancelled out almost perfectly, but a continually changing source like a human voice speaking will sound slightly different to normal, but be perfectly intelligible / clear because the headphones are only cancelling out what they heard a fraction of a second before that, so it never catches up. If they change their conversation from speech to a consistant hum then that'd be cancelled. Hope I'm making myself clear.

These are not noise canceling so you can hear a little. However, I listen to music pretty much on full blast and my husband can only hear very soft, muffled sound when sitting next to me but not enough to make out what I'm listening to or disturb the pertain next to you. If you're goal is total silence then you need to pay up for the nose canceling style.

They are good for noise cancellation of regular conversation. I use them at work and can't hear the other workers. I work in an open call center type of setup.
