Bose QuietComfort Ultra Wireless Noise Cancelling In-Ear Earbuds, Bluetooth Noise Cancelling Earbuds with Spatial Audio and World-Class Noise Cancellation, White Smoke

Why did you choose this product over others?:I chose these because the noise cancelling is superior and is fantastic for people who are in loud environments. You get passive noise cancelling from the ear tips being snug in your ear, then it’s your choice to add extra noise cancelling in the app, but a little goes a long way, and I’ve never needed it to half way or full.Charging speed:Charging speed is fantastic and never had the headphones go flat on me yet, even after heavy useComfort:Comfort with these earbuds is fantastic, they come with different sized ear tips, from small to large, so you can have a different size in each ear.Weight:The weight is fairly light weight and feel premium with a nice feel to themDesign:The design is small and compact, but don’t let that take away from the amazing sound quality, amazing and shocked me when I put them in the first timeEase of use:Very easy to use with touch control, the app is very intuitive, and plays a tone every time you put them in, but need to play it in the app settings so it tells you you if the seal is good or notBattery life:Fanatic as stated previously, never find myself having to rush to charge them after intense use

I've had a long line of Bose earphones/headphones and never had a problem. I was reading reviews (I always go to the bad reviews first) and really couldn't relate to the experiences.I've had every model of wireless Bose earbuds and think that they've got better and better. If you're not bothered about the immersive listening - then look for a pair of last year's QCII model, because I think that is the only difference.The fitting is a bit of a challenge initially, there is a bit of trial and error in getting both bits of silicon to fit just right. But it is worth persevering because that's where you'll get the optimum comfort and noise cancellation - once this is done you are set for good. The key reason I have persisted with Bose is largely comfort - I think that the silicon tips in all Bose earphones sets them apart before we even get to sound.Pairing with an iPhone and the app is pretty straight forward - although sometimes you are paired - you can see it on your phone's Bluetooth connections and you can hear fine, but the app doesn't think you're connected. But it seems to sort itself out.The sound I think is as good as any buds I've tried, I also own Airpod Pros and Sony's media darling WF 1000XM4. Both quite similar in sound - but not as comfortable - especially for long spells of use - and especially the Sonys which I find quite heavy. I've not suffered from any white noise or interference on sound. Through the app you can tweak the EQ to your taste - I've found that it is really not worth the bother.On to the Immersive Audio - this is the big change from the previous model. It's far from necessary but when it works well - it is very effective. I've largely been using Apple lossless and the results vary a bit. More recent releases like say Billie Eilish sound fantastic - genuinely immersive. On rock, where it works well you get a clarity and separation that unveils hitherto unheard details. Overall I like it and think it's a decent - if not entirely essential - enhancement. I do listen to most music with Immersion on - so I guess that says something.The only real niggle I have is the lack of wireless charging. Which you can have for £50 in the form of a silicon case on top of the supplied case.Overall these remain the buds to beat for me.

I'm a professional audio engineer and music producer and i had to send these back with very mixed feelings.After researching a lot I ended up buying these Bose earbuds. My priorities were a comfortable and secure fit and I wanted earbuds with the best possible ANC without passive blocking and decent sound quality.The pros:- The sound quality is quite good for earbuds. The lows are very emphasized but don't sound muddy. The higher mids sound a bit plastic but decent. The highs don't hurt and are actually quite silky. The stereo separation is quite good and the depth of sound is decent. The transient response is okay but nothing special.- The ANC is very quiet and the awareness/transparency mode is sick. You can hear everything around you but you can still listen to music at the same time. Activating it is a bit awkward though (tap and hold) it would be great if it was automatic like the apple earbuds. Some people said it sounds as if you weren't wearing earbuds but that's not true in my opinion. You can definitely tell that the mic is altering the atmos sound.Now the cons that ruined it for me:- The ANC has artifact problems in the left ear bud and i found several people on Youtube that have exactly the same problem so it's not only my product. I'm not talking about the constant static white noise that is audible when having the ANC on btw. It's some weird artifacts that occur randomly, sound a bit like a bit reduction. It's random and clearly audible and very annoying. It seems almost all models have this problem. Quite cheeky for 300 quid. (I asked the Bose support about this and they kindly offered me a replacement but not a refund after 1 day haha, i'm glad i ordered on Amazon.)- The Software is user friendly but simply doesn't work properly. (I have a Samsung S20 plus). It always takes ages to find and connect the earbuds and the connection breaks off all the time. It can't connect 50% of the times. It's very irritating.- The most upsetting (subjective) problem is that the comfort is terrible even though I tried all the different earbud combinations from the sizing kit. My ears are a bit smaller than average so the ear buds get loose when I'm moving a lot (they are never really snug) and then I need to adjust them without triggering the touch commands which is impossible. They also hurt my ears a lot when I'm adjusting them. The ear tips rub against my ear canals so my ears get really sore after only 1 hour of using them. Maybe my expectations were too high when it comes to comfort.- As already mentioned: the touch commands are way too sensitive. You trigger them all the time and then you need to tap them to get back to your initial settings. Touching the earbuds is very loud and hurts my ears. But touching them very lightly is a good and inconsistent workaround.- The immersion mode is overrated imo. It's a cool psychoacoustic effect but only people who aren't audiophiles would use that because it messes up the stereo field and frequency distribution. Can be cool for videos but it's definitely marketing bs and not worth the upgrade for me. My brain can't deal with the ANC and the immersion mode very well and I felt really dizzy yesterday.Conclusion:I'm disappointed with these earsbuds and i really wanted to like them. They just aren't as comfortable and secure as expected and they have technical issues. I was sad that i had to send them back because i researched so much before buying them. They look nice and all that but there are just too many problems. Especially for £300.
