The BOSE QuietComfort 20s are the latest members of the popular QuietComfort family, which for various reasons seem to have become almost standard field kit among business travellers and frequent flyers.
But unlike the BOSE QC3 and QC15 headphones which fully encase the ear, the QC20s are compact travel-friendly earbuds. The overall effect is eerily silent and the noise-cancellation circuitry seems even more effective for reducing general cabin conversation, although their magic remains ineffective on crying babies. In addition to smacking down ambient noise, the BOSE QC20s are solid performers with a bright top-end response and broad mid-range, although the flatter bass response makes them less ideal for doof-doof.
I’ve been using a pair of QC20s for the past month, which means enough international trips that the headphones themselves could qualify for Gold frequent flyer status. But the QC20s are also far more versatile than conventional headphones because a tiny microphone in the inline control unit lets them double as a hands-free setup for your smartphone. A switch on the inline control unit located partway down from the earphones temporarily allows the outside noise in so that you can hear the cabin crew when it’s time to order your meals or drinks.
The tiny speakers rest against the opening of the ear canal while the triangular wing of the silicone eartip fits into the contour of your ear to hold it in place.
As a result the earbuds rest in the bowl of your ear rather than being stuffed deep into your ear canal. One of my only criticisms of the QC20s is that this control unit is located too close to the earpieces themselves. A more basic oversight, and a surprising one for BOSE, is that a double-pin airline adaptor plug isn’t included on the handy QC20 carry-bag, despite being standard kit on the QC15 and QC30 models. The QC20s rely on a rechargeable battery, which is tucked away in a flat section towards the end of the cable. This charges up over any USB port, including those now found on many aircraft, but it takes only four hours of being jacked in to supply the QC20s with a full 16 hours of juice. And unlike other BOSE QuietComfort headsets, if the battery runs flat the QC20s still continue to work just like regular headphones.

The similar Sony product, around for a few years is cheaper,  clips to your shirt and has double-pin adaptor. I find that if you unplug the jack only slightly, leaving a milimeter or so of it out you wil get the sound of that one channel in both ears (still only the sound meant for one ear). Hi Jalmulla - yeah, a bit of fiddling with the plug hits that sweet spot in the socket so it's a good trick for 'emergency' situations without an adaptor, I've used it myself, but I prefer an adaptor all the same. Sony MDRNC13 and SONY XBA-4 seem to look almost the same as other earbuds except that the inside the Sony MDRNC13 housing, there are a circuitry to receive and invert wave from microphones which pick up the ambient sounds.
ANC earbuds (in ear headphones) work effectively on the sounds that constantly produced like air-conditioners or jet engines.
Literally they can’t since it relies on the working ranges of the noise-cancelling components, which is the range of frequencies that the ANC circuitry can generate. Not all noise-cancelling earbuds are comfortable to wear, effectively reduce noise and have long battery life.


Additionally, the noise-cancelling feature requires battery to run its function, which can be internal or removable and the longer battery life the better, and the Bose QC 20 offers the longest up to 16 hour with integrated battery. However, the battery box can be weighty that may tug earbuds out of ears. AKG K391 NC has the integrated battery that can last for up to 40 hours for streaming music with ANC function switched on.
Technology gives us a lot of awesome things, but it can also add up the problems, like the noise-cancelling if they malfunction or it was not cared much by the manufacturer ( they add this functions to advertise the earbuds on the market) you coud hear the intense background noise.
If you travel alot on train or flight, this clever sound cancelling technology could make you happier and more relaxed audio experience.
Hi, I guess you haven’t yet tried the AKG K391 NC the reason their battery lasts so long is that it doesn’t appear to cancel out any noise, it just makes the music louder !!
