Sennheiser HD 450SE Bluetooth Wireless Headphone, ANC, 30hr Battery, Black

(UPDATED) 12/17/22: Review of the Sennheiser HD 450BT (Special Edition) COMFORT The 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. SOUND The 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 QUALITY The build quality thus far is good and better than expected. ACTIVE NOISE CANCELLATION The ANC (active noise cancellation) is average at best, but does appear to reduce the outside noise by approximately 35%. BLUETOOTH WIRELESS and WIRED CONNECTIVITY The 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 APP The 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 ALEXA The 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. CHARGING I do not believe these are considered fast charging as it took 2 or more hours to fully charge. RECOMMENDATION I 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.

Bought this headphone 4 years ago and still works like new, no problem with the sound or connectivity, really great product, the battery still holds the charge for more than a day !!! Easy to pair with other devices !

Battery life seems good, although I haven't rigorously measured it. Sound quality is exactly what I've come to expect from Sennheiser, which is why I keep buying them. The ear cups are quite comfortable, while the headband is merely OK. It could use some more padding. Bluetooth pairing is easy the first time, and much faster to transfer audio than my last pair of BT headphones. Two downsides: the noise canceling function is on by default, every time you turn the headphones on. I really only want noise canceling for airplanes, not for home use. You can turn it off, but it'll come right back on the next time the headphones do. Second, all the controls are clustered on the right earpiece. Since there are four controls and 2 plugs (USB-C and 3.5mm), it can be a bit annoying to find the one you want, whereas splitting them between the two earpieces would lead to less confusion and fumbling. I want to say these are minor quibbles for an excellent pair of headphones. You could pay twice as much for Bose and not really get a better product.

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.

I am a fan of Sennheiser and have used its products in the past. But this pair of active noise-canceling headphones is a true letdown! Pros 👍👍👍 - Build: Solid with no creaks or gaps. - Compact: They fold down and pack small. - Comfortable to wear with room for adjustment. - Versatile: they can be used wired & wireless. - Battery Life: up to 30 hours with USB-C fast charging. - It comes with a carry case. - 2-year warranty is commendable. Cons 👎👎👎 - Controls: A bunch of buttons crammed together with no rhyme or reason, no labeling, and no easy way to navigate by touch! 😑 - Voice Prompts: It tells you everything, except for the one thing you need the most—it won’t tell when ANC is on or off! It’s infuriating! 😤 - Active Noise Canceling (ANC): It makes a difference, but it’s negligible at best! - Audio Tuning: Everything sounds flat and lifeless, with volume bouncing up and down inexplicably! 😳 - No Proximity Sensor so they don’t pause when take them off which is real nuisance 😑 - SE stands for Special Edition, but I can’t figure out what's so special about them. Seriously, what is it?🤔 - The Price You Pay: At $200 MSRP, this set is a hard sell! On sale for $80, it’s still a pass for me! Pay a few bucks more and get a Sony WH-CH720N, or if you’re on a really tight budget, get Anker’s Soundcore Q20 for $40–$60. My Verdict 🧐 I am not here to bash Sennheiser or throw shade at its good name, but I cannot in good conscience recommend this product, especially if you’re planning on using it while traveling. Skip this or suffer buyer’s remorse! You may think I’ve come down hard on Sennheiser in this review, and maybe I did, but those headphones are the worst I’ve ever come across, except for only the Koss KPH7, but those were $20 and made no claims to greatness! I hope my review will help you make a more informed buying decision 👍😊✌️

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.

I love these headphones, got one for me and a friend. We both agree that the sound quality is amazing, just a little neutral out of the box. It comes with a great app for adjusting the EQ to your personal preference. The headphones are comfortable and I can wear them for hours on end without fatiguing my neck. I love being able to quickly adjust the EQ in the app based on the music I feel like listening to, and the ANC is great. It's not the strongest ANC I've experienced, but it definitely helps drown out the background noise around you, and you can turn it on and off with a simple single press on the power button. Overall great headphones!

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.
