Despite this, I frequently use these headphones while operating heavy equipment and can hear the music loud and clear with very little background noise from the noisy machines.

These headphones do a very nice job of quieting the background noise of these appliances.

It doesn't block out everything, but all of the background noises on airplanes and trains were tucked away very nicely.

The headphones do a good job of blocking a lot of background noise irrespective of the noise cancellation feature.

The headphones fold well making them a bit more portable, they are secure on the head, they block out background noise and they do not leak noise

There is some subtle background noises that disappear when the unit is powered on thereby activating the noise reduction feature.

People on the other end tell me that I sound clear and natural through the Sennheiser's mikes which also screen out background noise.

Sound quality is good, they do a good job of attenuating background noise, last a long time on a charge, and I don't have to worry about getting cords stuck on things

When testing the mics usage via cell phone, I received reports of adequate sound quality when speaking under quiet conditions, but was told, in no uncertain terms, that they sounded "irritating" when used at only 45 mph, on a smooth road and with the windows up, due to the background noise.

The slight background noise drives me a bit batty, but these are a bit different in that regard

You add the superior sound quality at a low volume and noise canceling amount is good enough to allow listening to music at lower volumes vs. high volumes to combat those background noises.

There is just less background noise, and that which comes through is mostly in the vocal

During the day I work in a laser lab with a fairly high ambient noise level and these cans simply cut the background noise to nil - verrry nice!Controls consist of a on/off pushbutton and a 3-way switch which controls everything else.

can always hear me very clearly even with a ton of background noise

While I haven't taken these on a plane yet, just wearing them at work I am amazed at how there is absolutely no background noise.

I want background noise eliminated while I listen to classic rock, blues and

Background noises are not nearly as dampened compared to the QC35 and M2

Buy the Sennheiser HD1 and truly cherish how music was supposed to be heard in comfort & with most background noise tuned out

Noise cancellation is good though background noise is not completely removed

If you've never used noise cancelling before, these will not remove all sound, but do an excellent job of removing background noise

The competition includes the Bose QC35s, the Sony WH-1000XM2, the brand new B&W PX (which is basically the excellent wireless B&W P7 plus noise cancelation).The Senn HD1’s have some things in common with these competitors.

The B&W look slightly more elegant and are more compact, but with less range and no noise cancelling - which could be viewed as a positive in that there is less processing of the audio.

I am spoiled by a stereo system with Emotiva electronics, and the very expensive B&W nautilus 800 series speakers, but I am satisfied listening to my TV and MP3 and FLAC files off my laptop with these headphones.

It is possible that the B&W's are better for a bit more money, but am unable to compare.

The noise cancellation is okay, but nowhere near the levels of the Bose QC35 or Sony WH1000.Overall there's much better options for this price that sound almost as good, or even better.

The mid-bass hump I experienced in passive wired mode was completely gone and smoothed out as soon as you enter active mode

These are every bit as good as I'd hoped they would be

these headphones sound almost as good as my wired B&O H6 2nd Gen headphones

It's not as good on these as on any of their competitors, but it doesn't suck

Comfortable to wear for 8+ hours on flights or when working as long as you adjust the cups properly and don't have them putting pressure on your ear

However, they don't sound nearly as good as the Sennheisers and also will leave your scalp in a world of pain after 30 minutes.

The earcups aren't as soft as on other products though, and for an over-ear the cups are surprisingly small, so if you have huge ears you may want to try these before you buy

So if you're buying them because they sound better than the Bose, don't bother as they are larger and won't play high quality files

I have also noticed that the noise cancelling does not seem to be as effective as with the 550s, but I do not notice as much wind buffeting.

The noise cancellation is not as great as I would have hoped, but much better than my last pair of headphones which were "on ear" and did not really block anything.

Those who prefer a warm, focused, bass-forward sound will prefer the Sonys

I generally love Sennheiser products b/c of their quality and reputation, but the awful wireless performance of this headset especially at this price is unacceptable

Some fault the B&O for having finnicky touch controls; these have no touch controls and only 2 buttons: on/off, vol up/down

In terms of high-quality plastics mixed with metal bones, they are more a peer to the less expensive Bose and Sony; the B&O clearly wins in build and material quality

so if you already have good headphones you may not be as blown away by these as I
