<!DOCTYPE html> <html><head> <meta charset=3D"UTF-8"> </head><body><p>Hi, I received a lot of recommendations for noise cancellin= g ear buds, and the one that popped up most often was Bose QC35.&#160; Unfo= rtunately, it also seems that those are a bit out of the $150 price range (= but some said there might be after market available).&#160; In any case, th= e responses are tallied below, and many thanks to all who responded.<br></p= ><p>Brian<br></p><p>***************<br></p><p style=3D"margin-bottom: 0in; = line-height: 100%;">I had two sets of noise cancelling headphones, one Sony= , one Bose quiet comfort 35 II. The Sony sounded good when playing music an= d were cheaper, but the Bose are vastly better at suppressing background no= ise. In my limited experience, if suppressing background noise is needed, t= hen your sister should try to avoid making a false economy. She can probabl= y try the QC35 in a shop. They are astonishingly effective.&#160;</p><p sty= le=3D"margin-bottom: 0in; line-height: 100%;">&#8230;.</p><p style=3D"margi= n-bottom: 0in; line-height: 100%;">These are considered the best noise isol= ation earbuds: &#160; <a href=3D"https://isotunesaudio.com/collections/earp= lug-headphones">https://isotunesaudio.com/collections/earplug-headphones</a= ><br></p><p style=3D"margin-bottom: 0in; line-height: 100%;"><br></p><p sty= le=3D"margin-bottom: 0in; line-height: 100%;">I didn&#39;t buy because of t= he difficult shipping to my country and finally I bought beyerdynamics DT77= 0M which are only isolating headphones (not cancelling) but I can say that = they are the headphones for me in order to work quietly in office.</p><p st= yle=3D"margin-bottom: 0in; line-height: 100%;">Anyway this is only my perso= nal point of view, lot of people prefer small earplugs instead of cumbersom= e overhead headphones, so I really suggest to visit the site above where yo= u can find the product for your sister.</p><p style=3D"margin-bottom: 0in; = line-height: 100%;">&#8230;.</p><p style=3D"margin-bottom: 0in; line-height= : 100%;"><span style=3D"font-family: Times New Roman, serif;" face=3D"Times= New Roman, serif"><span style=3D"font-size: medium;" size=3D"3">We evaluat= ed the attenuation provided by Etymotic HF5 noise-isolating earphone (cost = &#60; $150) in a sound-attenuating chamber using three different ear tips p= rovided by the manufacturer.&#160; We measured speech recognition threshold= s (SRTs) using spondee words in the sound field with both ears of the subje= ct plugged by the ear tips. Four participants were evaluated.&#160; The ear= tips evaluated were&#160;the Etymotic Research ER38-15SM 3-Flange Ear tips = (size small), ER38-18 Large 3-Flange Ear tips, and the ER38-14F Standard Bl= ack Foam Ear tips.&#160; &#160;The foam ear tips provided the most attenuat= ion, which is approximately 20 dB.&#160;</span></span></p><p style=3D"margi= n-bottom: 0in; line-height: 100%;">&#8230;.</p><p style=3D"margin-bottom: 0= in; line-height: 100%;">I use a pair of Bose QC35 to shield myself from the= NYC rumble and I&#39;m very happy with them. But... they&#39;re over your = specified budget, probably because they are wireless. The wired version, th= e QC25 costs ~$180 in the US, which is closer to what you&#39;re looking fo= r. A lot of brands have noise cancelling models these days (Sennheiser, Son= y,&#160;etc,), so it&#39;s worth looking around.</p><p style=3D"margin-bott= om: 0in; line-height: 100%;"><br></p><p style=3D"margin-bottom: 0in; line-h= eight: 100%;">That said, it&#39;s also worth bearing in mind that noise can= celing headphones are especially good at removing low-frequency relatively = stationary noise (like traffic and airplane &#34;hums&#34;), and less good = and removing high frequency non-stationary sounds (like speech) - so depend= ing on the source of noise in your sister&#39;s office the headphones will = have more/less effect.</p><p style=3D"margin-bottom: 0in; line-height: 100%= ;">&#8230;.</p><p style=3D"margin-bottom: 0in; line-height: 100%;">I have t= he same problem as your sister.&#160;</p><p style=3D"margin-bottom: 0in; li= ne-height: 100%;">I know it&#39;s above 150$, but I got Bose QC20 noise can= celing earbuds for my bday and they are just amazing (250$).</p><p style=3D= "margin-bottom: 0in; line-height: 100%;">I also tried my colleague&#39;s Pa= rrot Noise canceling headphones, and they are nowhere near as good.&#160;</= p><p style=3D"margin-bottom: 0in; line-height: 100%;">&#8230;.</p><p style= =3D"margin-bottom: 0in; line-height: 100%;">Sadly for your wallet, ANC is r= eally where Bose shines.&#160; They&#39;re generally overpriced, in my&#160= ;opinion,&#160; but not in the case of noise cancellation. The QC35s come u= p for sale fairly often, so you might be able to get close to $150.</p><p s= tyle=3D"margin-bottom: 0in; line-height: 100%;">&#8230;.</p><p style=3D"mar= gin-bottom: 0in; line-height: 100%;">I tend to like the sound of Audio-Tech= nica headphones, and they now make a few noise-cancelling versions that are= cheaper than their Bose or Sony counterparts. For example:</p><p style=3D"= margin-bottom: 0in; line-height: 100%;"><a href=3D"https://www.audio-techni= ca.com/cms/headphones/c4ca191ebf334d8f/index.html">https://www.audio-techni= ca.com/cms/headphones/c4ca191ebf334d8f/index.html</a><br></p><p style=3D"ma= rgin-bottom: 0in; line-height: 100%;">&#8230;.</p><p style=3D"margin-bottom= : 0in; line-height: 100%;">Not science but I have been using the HF-5 (and = pre-cursor) for airplane travel for the last 15 years and I love them. I al= so have the much more expensive Bose NC headphones but I find the Etymotics= are much better for listening to a movie on the plane.</p><p style=3D"marg= in-bottom: 0in; line-height: 100%;">I use the foam tips mostly.</p><p style= =3D"margin-bottom: 0in; line-height: 100%;">(as the in-ears are most effect= ive in higher frequency but the active noise cancellation is more effect in= the lows, putting the Bose OVER the HF-5s is amazingly quiet J)</p><p styl= e=3D"margin-bottom: 0in; line-height: 100%;">&#8230;.</p><p style=3D"margin= -bottom: 0in; line-height: 100%;">On the plane, I use a pretty low tech app= roach. I like to wear standard phone ear buds with hearing protection style= muffs on top. The hearing protection muffs give around 30 dB protection ac= ross most of the spectrum. At the hardware store, the muffs typically give = attenuation ratings vs frequency in their specifications on the packet. If = you get a version with deep shells, then the ear buds don&#39;t even touch = the sides.<br> <br> It may look a little excessive in an office environment= !</p></body></html> =20
