Hi,
Here's my thoughts on these.
I had been lusting after these or actually the QC15 ever since I tried them at a Bose store but was always apprehensive of the price that comes along. I also looked at a couple of other cheaper options and actually bought Audiotechnica ANC-33IS last week.
Tried them on a 10 hour long flight on exit row window seat. Not impressed. I guess that seat has plenty of other high pitch noise which no NC will be able to cancel. Besides noise cancellation they are no where near as good as the Audiotechnica ATH-ES55 I have as my regular headphones.
So I am on my way back and found the QC20 at a nearby Bose store for USD 199.00 Factory Renewed. I could not let that by, I was prepared to spend USD 239.00 for a promotion they had going for QC15 but that ended when I actually went in to buy but found the QC-20 instead.
As a background into what I listen to... mostly instrumental guitar and very little lyrical music but 99% of the times it is Buckethead, Joe Satriani, Steve Vai, Dave Sharman...
This is the kind of equalization I apply...
I had purchased Shure SRH-440, Audiotechnica ES-55, AKG-K451 and some Creative earphones but finally decided in favor of ES-55 as the "go-to" headphones. Kept the K451 as "maybes". Shure lost mainly due to portability and Creatives were not in a level playing field anyways. ES-55s are particularly super excellent at what I listen to.
SO, I have tried the QC-20 in somewhat noisy environment and this is what I gather from my use for the last couple of days
- There IS a noise floor. It IS noticeable if no music is playing. So if you are looking at buying them purely to block out the noises, you'd be better of using ear plugs OR one of those 3M noise protection products.
- Audio quality is NOT good with NC turned off.
However with NC turned ON...
- The equalisation I apply works beautifully well !
- The soundstage is somewhat even less constrained than ES-55 and I haven't noticed any loss in fidelity as yet. The ES-55s are a little brighter but I have to turn the volume up to get the full effect. QC-20 have ever so slightly smoother/weighed down/buttery sound signature BUT I like the sound and can live with it.
- When riding the tram (the downtown San Jose to Mountain View route if someone is familiar), with NC turned ON... I am indeed blocked away from noises if there is music playing through them. I am currently using iPad mini(retina) as the source and keep the volume at Level 5. It's somewhat uncanny experience to begin with but it makes that journey VERY comfortable.
- In the office, they are able to cut off the HVAC hum, and surprisingly if there are people talking maybe 3-4 feet away, those are blocked out as well.
In SUMMARY, I like them so far. NC actually works (works better than cheaper Audiotechnica ANC earphones). They are comfortable. I can sleep with them on (just use a softer pillow).
The Audiotechnica ANCs are going back to Amazon. I might even sell off the ES-55s to dilute the cost of QC-20s.
The final test will be on my 11 hours long return flight again on an exit row window seat with all the noise that comes with it.
Here's hoping it was money well spent.
