(UPDATED) 12/17/22: Review of the Sennheiser HD 450BT (Special Edition)COMFORTThe only thing I was worried about was comfort as some of the reviewers complained about the fit being too tight and or runs hot, which I found not the case for me.SOUNDThe sound was well balanced (lows, mids, highs) out of the box, even though the built-in Smart Control app controls the equalizer, which has presets for genres and is customizable to some degree. The bass (lows) are actually adjustable slightly in the Smart Control equalizer and iPhone settings, so the bass (lows) are better than expected.BUILD QUALITYThe build quality thus far is good and better than expected.ACTIVE NOISE CANCELLATIONThe ANC (active noise cancellation) is average at best, but does appear to reduce the outside noise by approximately 35%.BLUETOOTH WIRELESS and WIRED CONNECTIVITYThe Bluetooth codecs will be more than enough to please the casual audio listener and on any device. Since these headphones also have wired cable connectivity (better than Bluetooth, playing lossless uncompressed audio), these headphones are all that is needed. The one odd, whether you take it as good or bad, is the audio cable connector is keyed. This provides a locking type of connection so that the cable does not wiggle or loosen easily. Connecting the cable takes getting used to, but works well.SMART CONTROL APPThe Smart Control app has limited functionality. It is too bad you can't control the functions in the app that the physical buttons provide.AMAZON ALEXAThe SE (special edition) version includes Amazon Alexa, if that is important to you, but other than this, both models are identical. I didn't need Alex, but the SE was quite a bit cheaper during one of the Black Friday or Cyber Monday deals for $75.00.CHARGINGI do not believe these are considered fast charging as it took 2 or more hours to fully charge.RECOMMENDATIONI would recommend these headphones at any price range whether at retail or reduced, because of the sound and build quality as well as the other numerous features it offers.

I bought these at the same time as the Beats Solo3, and compared to those, the sound quality on these is wonderful. You can hear the separate instruments, which especially matters if one is listening to accoustic music. There is an equalizer app one can download to boost the treble, bass or midrange. It won't give you super booming bass, but perhaps other apps do - I haven't tried any yet. What I mostly like is that the audio is natural and full. The Beats offer more bass, but it's at the expense of compressing the audio. I can't say much about the noise cancelling capabilities, since I use these mainly to listen to music, but if they cared as much about that as they do sound quality, I assume it can't be all that bad. The size of the earpieces seem a bit large, but they are extremely comfortable. I have worn these for hours at a time, whereas with the Beats Solo3, I couldn't stand them for more than 45 minutes because they squeezed my ears and head so hard. The controls are a bit tiny and took some getting used to, but they worked fine. The power button on the Beats cannot be felt by a normal hand unless you can read Braille - it is flat, tiny, and impossible to locate. In short, if sound quality and comfort matter to you - the Sennheiser HD 450 SE wins hands down.

Awesome headphone! Confident sound quality and noise cancelling that just works very very well. Why missing one star though? Two reasons -1. Mic only works well if you’re in doors. Even the slightest background noise and it’s unusable.2. I share this headphone with my SO. Every now and then it’ll connect to both our phones, and then when I head out for a walk, it’ll keep saying lost connection indefinitely. The only solution is a power cycle. This is something that can be easily fixed in firmware.

I was really excited about my first pair of “good” wireless headphones. I’ve had great experiences with Sennheiser in the past, so I was confident this was going to be a reliable purchase.Like I said, during the first months it was all going great: pairing was lightning fast, audio range was incredible (could leave my phone in the kitchen and walk 10-15 m away with no trouble whatsoever), and the sound quality was pretty good. I was beyond happy, thought I’d found gold since I got them on sale for like 40% off.Then one day I remember I let the battery run out, and thought “Crap. Oh well, I’ll recharge them and use them in a couple of hours.” They started to make weird noises as I turned them on and tried to get them to pairing mode, like interference sounds or something glitching. They weren’t able to connect again, so I deleted them from my phone’s device list and tried to pair them from scratch again. Didn’t work either. They also wouldn’t turn off, and the factory reset didn’t help at all. It was like they couldn’t maintain pairing mode for more than 3 seconds and then restarted themselves (all while still making those funny noises in the background, perceivable only with the headset on). Suddenly one day they decided to work again, and broke down once more after a few weeks.I’ve decided to keep them wired to my laptop, but id you’re buying them thinking they’re that affordable pair of tw headphones you’ve been looking for for ages, I’d say keep looking.PS: ear cushions make your ears all hot n sweaty.

for the first 6 months this product was pretty good. the sound canceling is okay, not as good as some other headphones within this price range, but does the job still. I have a pretty loud PC as well as a personal fan that will run and it does a good job drowning out those noises. traveling outside of the home can be dodgy, airplane sounds aren't as muted as i'd like and it doesn't really drown out talking, which is fine. the biggest issue i have with these headphones has been connectivity.it can be a big pain to get it to connect to computers, and it does this thing where every three connections you have to reset and reconnect all over again. i can connect it to multiple devices like my phone and computer, but the sound only comes from one unless you accidentally hit the voice to text button and then suddenly nothing works until a few seconds after you stop the voice to text. within the last month it's been dropping connection altogether and the only thing that gets it to connect is to turn it off and on. it makes a really loud noise when it does this as well.the funniest part about this headset I will say is the british lady who will at the most random times tell you your battery life. it's extremely funny when you record a dnd audio drama and you're in the middle of an intense scene and she just inexplicably says two hours into using the headset "between 6 and 12 hours play time".the headset charges fast and does hold it's charge for a long time. i can go days of regular use before needing to recharge, and i can generally get another 4 hours of charge in 10 minutes in a pinch. they are comfortable to wear if you can get your full ear into them, however not as comfortable if you wear glasses like i do. if you can tilt the arms of glasses up though it is comfortable. the headband part of the headset does have give to it, and doesn't give me headaches.all in all it's a descent headset for the price, i'll most likely be buying a new headset soon however, as the way it's been dropping every couple hours is getting really frustrating.

For years I have heard of this brand so for Christmas I decided to give myself these headphones as a gift to me, I must say I’m beyond impresses with the sound. The noise cancellation is spot on and the bass hits just right, honestly no insult to Beats or Bose but I’ll say that these are definitely my go to over my Solo and Bose headphones. Now for the negative like others wrote making and taking phone calls on it is not good at all, the headphones act weird when using those features. The verdict, I your strictly into sound quality this is your headphones. To be amazed I would recommend playing songs with live instruments and sounds example DC GO,GO or a live jazz set, just my recommendation but I hope this review helped

I bring a tablet and these to the gym and watch movies while I exercise. Excellent sound quality and a good firm fit so they stay on your head at the gym.This setup makes the exercise time a lot more enjoyable.The only down side is the controls are tiny and not labelled.

Hey y’all. I really wanted to like these. I had heard great things about Sennheiser and was really hoping for a set of headphones that prioritized sound above trendy tech features. Unfortunately, I bought these in late November of 2023 and the left ear stopped working completely in September of 2024 after having developed a distorted, muffled sound and random beeping and screeching while connected and playing audio several weeks beforehand. I’m going to try and get a replacement, but honestly, even before they broke, I was very underwhelmed when I received these. I bought them as a treat for myself to upgrade from a random pair of off-brand headphones I had had for three years and worked fine. When I got the 450SEs, I was expecting to hear a noticeable difference with my FIRST EVER pair of on-brand, quality headphones… and there was barely any. I messed with the equalizer, the app they come with, everything, and honestly was just not impressed. I’m no audiophile, so I don’t really know the correct terminology to describe this but… the sound just felt empty and hollow. I’m not even a huge booming bass person—I specifically bought these because I hated the bass on the Sonys I tested out. Also, the dual bluetooth functionality never worked for me and I had to disconnect and reconnect to switch devices just like any regular ol bluetooth device or risk blasting my youtube video out loud in the office. Super disappointed in that as well. Maybe if they give me a replacement and don’t try to skip out on my warranty because I purchased through Amazon or something my mind could be changed, but right now I couldn’t recommend these. Heck, go pick up a pair of taotronics. They’re far cheaper and the same quality and saved me from the worst freshman roommate anyone has ever had with their noise cancellation.

The Headphones is Almost perfect, Great quality & Sound , with the Application you can adjust the sound as you prefer.You can close the Active noise cancellation as well with the buttons .The only downside is that it will warm up your ears.The Bass is decent but not boomy.

Good noise cancellation. Quality sound. Definitely worth it!

Excellent matériel, qualité audio inégalée. Un constructeur qui est à l'écoute de sa clientèle.

Great sound. Really comfortable too.
