Alright! I got the headphones and I want to share all my thoughts and everything I notice! I am an audiophile. But this is great info to have if you see yourself considering the Bose QuietComfort Ultra Headphones. So I want to start off by saying listening on Bluetooth is no longer an issue! Bass sounds solid down to about 20hz on Bluetooth! With no artificial bass sounds which are present on the QC35’s and 45’s. This is a huge deal for any listener! It’s a whole new world when you have bass that is responsive and doesn’t sound artificial! There is no sharpness/fatigue in the treble regions! Which is amazing! It allows users who want a more treble forward sound to go right into the Bose music app and bump the treble up to their desires!… The harmonic distortion that is present on the QC35’s and 45’s is not present at max volume with the Ultras! BUT… the volume seems to diminish the more you turn the bass up on the headphones. Which is not cool at all. Bose could easily fix this in a update. I prefer my bass on around +4 or +5 with my treble sitting at +1 or +2 depending on the source. I listen on my iPhone 14 pro max via Spotify premium, Apple music payed subscription and tidal’s highest subscription offering. Each one offers things the other does not. But this isn’t a review of steaming platforms. It’s a review of the headphones! Yes these are the headphones to get! They are a absolute upgrade over the QC35’s and 45’s. My question I wish I could ask Bose is “why did you release the QC45’s knowing they were going to release these?” They were hardly a upgrade over the 35’s… I was not a fan of the NC700 sound quality so I returned them. Now onto the next question all of you reading have! The proprietary “immersive audio” experience bose offers is very nice for SPECIFIC GENRES. DO NOT EXPECT TO BE BLOWN AWAY IF YOU ONLY LISTEN TO RAP AND POP. Where the magic lies is with instrument and vocalist focused music. Anything acoustic, anything live. Anything vocal based… I’m gonna share some songs I had bad and good experiences with while listening in immersion modes. Songs like “growing pains acoustic” Alessia Cara sound way too artificial and un natural! Which was a let down! Then other songs like “Not about angels” By Birdy brought me to tears or “Stole the show live from Spotify studios” by kygo sounded just ok. but it did not bring me to tears. I noticed that the immersive mode really can diminish a lot of the “live echoic” ambience that the live recordings have. But it can also add to certain live songs. It’s definitely hit or miss depending on recording and genre… immersive audio is a hard topic unfortunately that many average consumers think will make their hip hop music will dramatically make every song sound better. It won’t… over all I’m in love with the natural bass Bose has finally manage to pull off with their QuietComfort line. And it’s a very very welcome upgrade. The smooth but semi laid back treble is much welcome especially knowing if I want a bit more sparkle I can simply go into the Bose music app and add more treble. And yes these settings do save when you use the aux input for gaming or if you are an audiophile like me and want the best quality possible. If this helped you! Let me know! I’m very happy with these and they will be replacing my Bose QC45’s.

Hey guys!
I'm decently new to reddit in terms of posting but I wanna start doing so because I am that friend in the group where people ask me for advice on which headphones / earbuds to get just cause I really love audio equipment!

In terms of wireless headphones, I have tried the Bose QC Ultras (returned them), QC45, NC700, Sony xm4, Airpods Max, Airpods pros / 2, Sennheiser momentums, Beats studio and my other favourite now Soundcore QC 35.
This review will be in the perspective of purely Noise cancelling wireless headphones, so sound quality will be compared to that and not wired. Remember, this is a $550 AUD premium headphone as you read this review.

1. Comfort

• Within all the wireless headphones that I have bought, bose has always nailed it with comfort imo. Not surprising since they're pretty much a airline company before a consumer company, comfort plays a part for long flights. The Bose QuietComforts are in the same design range as the 45s and 35s so that soft boobiesque cushions on your ears all fluffed up and so much space that airs your ears like the open spaces that we will never get in this era of governments taking over the land, its really comfortable. Long gym sessions and flights of (8hours) all the way straight has been very easily worn and little to no fatigue for me. Compared to the ultras with shallow earcups, it does get hot after a few hours and for me the clamping force of Airpods Max can be a tad too much. So do with that what you will.

2. Noise Cancelling / Transparency

• This is THE reason why I upgraded from the QC45s. Outdoor mode. One simple tech change that changed everything for me. Essentially what outdoor mode is it only uses the noise cancellation mics in the earcups. So when wind is strong like the strong bitchy melbourne winds are, it wont affect the noise cancelling and thus wont have that harsh wind noises when the noise cancelling mics on the outside are turned on. The outdoor mode is more than enough to cut out most noise outside, for me loud noises include the Treadmill, people screaming as they drop a 10kg dumbbell (for some reason?). - Quiet mode, which is turning on all the mics for noise cancelling, is amazing for when you really wanna get into a podcast, movie, or whatever focus modes you need when you're in a still quiet room with maybe a fan running, or a coffee shop. It really drowns out almost everything.

• I was able to play a movie in my room at probably 40% volume with a fan right beside me, neighbours talking loud thru the halls as if they're at a rave, And when this mode is on, I can't hear any of that. To be honest I have to lock my door just in case my rooommate or whoever jumps in and give me a jump scare so yes. - Lastly, "aware" mode, honestly not on par with the Airpods, its good, its natural, but still a little shallow. I would only use it when I want to be aware of my surroundings, like traffic, or overhearing people's conversation in the library and them thinking I cant hear them (please tell me im not the only one). But to use it while having a normal conversation or ordering a coffee, it's kinda tough, id have to take one ear out. With the Airpods pros and Max, transparency is done amazingly well that you could talk without taking an ear out (of the earcups of course unless you have wireless ears).

3. Connectivity + Buttons

• ANOTHER reason why I returned the ultras. That sliding piece of crap that slides accross like a waterslide is horrendous. The tactile buttons of the Quietcomforts are easy to press, easily distinguishable and nothing for me to complain about. On Off slider? Apple? APPLE...? APPPLLEEE.. but yea really can't complain or praise too much, it just works as a product shouldicrophone

4. Microphone

• Not the best, but gets the job done. Speaking at regular volume or soft usually works more than find indoors and outdoors. Then again thanks to IOS's voice isolation mode that helps alot. So if you're using an android, ask chatgpt to helpout idk mate.

5. Sound Quality

• A lot more full than the QC45 imo. With the bose App and eq, I find myself with the bass up +5 to get a really good thump especially in the gym. The one thing that makes me unable to return to the soundcore is the clarity of bose. Bose and Apple has always nailed the vocal clarity that I always so desire in my music. Be it metal, kpop, (stfu i love kpop), pop, acoustic and podcasts. To have something that really thumps with the bass and clear vocals is something that's really hard to find. Comparing it to the XM5 and XM4 which to me is slightly too bloated in the mid bass. With these Bose, it seems to be the best compromise for me in the wireless scene. Though the soundstage isn't the best, it is fairly forward, the instrument separation feels very Left is left, right is right. rather than if something was on the right 90, or right 45, right 32 whatever it is, its all just right. But really in the wireless world, you can't get the best all in one in terms of sound, so take that into accoun

6. Complaints

• To be honest, this is my favourite wireless headphones so far that I paid full price for and have no regrets. I really have no complaints with it, it could use better soundstage but to be honest, when I'm doing my work, or in the gym, it does what it needs to do, get me focused. - My Main complaint would be the naming. I would LOVE to recommend these headphones to more people but it's so hard to make people understand with the naming. I UNDERSTAND why they did it, Bose is killing off all previous names and now just making two headphones.

• Bose Quietcomfort, Bose Quietcomfort Ultra. Sort of like Iphone 15, Iphone 15 pro, Samsung S24, Samsung S24 Ultra. I GET IT. BUT, they're still selling the bose quietcomfort 45 and Bose NC700, and my god, when you put it all together it is a cluster ****, its like my mum never being happy with how I vacuum the floor and always telling me i'm wrong and can never actually get me to do the right thing. I just can't recommend it to the normal person who just wants good noise cancelling headphones. The only way IMO this naming would work was to do a proper announcement (which bose doesnt do) or kill off the previous generation of products, either way, that's just me complaining

7. Overall Feeling

• Overall, in my personal opinion, anyone who gets these headphones will NOT be dissappointed. Though I would recommend to get it when there's discounts. And trust me bose does have discounts, ALOT. Literally 2 weeks after i bought this at retail price it dropped $100 on Amazon. Like what in the actual **********. But whatever it is, I love these headphones. I will always end off a review by saying know what you like, know when you're gonna use it, and you'll have your best answer. But for me, this confusing ass one hell of a headphone is a solid 8/10 for me.

edit: please bear with me on the format im still new :')
