I have been blown away how long these headphones have lasted. They were purchased some time in 2010 and have been worn 8 hours a day 5 times a week since then. I’ve had to replace the ear cushions 3 times and the cord once. They just take AAA batteries (I got rechargeables) so no BS battery packs that you can’t service. They aren’t wireless but because of that they are super light weight. On the used market they go for ~$40 now a days and are totally worth it if your in the market.

Hi Everyone,

So I jumped the gun on BlackFriday to replace my old trusty QC15s which have been with me almost a decade. I thought getting rid of the audio cable and getting a bit of a technology refresh as well would be nice.

Having followed the products being released over time the QC25, QC35s and now last QC45 I had the impression that each generation was a bit better than the last. Atleast that's the impression I got from reading reviews.

I have mainly used the QC15s at the desk when working on the computer while listening to music or taking zoom/teams/skype/hangouts calls and of course while traveling.

When I now have received my QC45s I am almost at a loss for words. Yes the ANC is better, but the sound quality is so bad compared to my QC15s I am almost speechless. Especially when playing music. It sounds so flat and hollow. And from what I read there's little room to fix this as well. The 700s are now the premium headphones if I have understood everything correctly and does have EQ- and boy are they ugly. Even though the bluetooth delay is not so bad, I am amazed they didn't even include a 3.5mm cable in the box.

If this is the "best" bose has to offer from the QC series I must say they have regressed massively.

Am I alone in thinking this? Is there something i'm doing wrong here? Perhaps some setting somewhere? and I have the correct bluetooth settings on my computer.

Just massively disappointed in this - the ANC is better than before but the sound quality is far below QC15 released in 2009!
