Bose QuietComfort 2nd. Generation Headphones. I'm really not big fan of Headphones I prefer Earbuds because I always thought they have a better sound quality. Well I think I changed my mind because of this new Bose Headphones. Absolutely fantastic Active Noise Cancellation with excellent adaptive behaviour. They have new Cinema mode when is a better dialogue clarity for movies. It is very good bass even at higher volumes without sacrificing details. Of course as usual is a Premium Bose sound when balance between bass and treble is perfectly in the point. Just fantastic. I love music. I listen music everyday at work, exercising,at home anywhere I can. I enjoy to listen music at this headphones plus they have a Spotify Tap which I love. Some people might say that over ear headphones are heavy but I don't really think that's the case in this Bose model. I even forgot that I have them on the head because they don't feel heavy. Also If you like you can still use them wired to music source as they coming with two cable's USB-C and 2.5 mm. analog jack input cable. So you don't need to use them just via Bluetooth. Bluetooth 5.4 is good as you can connect them to more than one device. I using them going around the house or gym without losing connection with my phone. When I make phone calls I have very clear voice sound and everyone can hear me clearly as well . Even when I've been in very loud environment. Also ,what I like, they have smart head detection so they turns on when you wear them and turns off when you fold them. Battery, I think it's improvement here, is strong. I think I used them for something around 30-40 hours without charging.So I think that's really good. So generally you can't be disappointed. Premium quality of Sound,Premium materials,three connection choices, beautiful Bass and absolutely incredible Active Noise Cancellation. Just Brilliant even if you are not music connoisseur.
