Customer Reviews

[This review was collected as part of a promotion.] I like these headphones a lot. Just want get that out of the way. They're comfortable, sound great and they look good. There's easily 33 hours of listening / talk time in each complete charge. I had no problems wearing them for long periods of time. I used then for a light workout( I don't recommend using these to workout in.) and they did well, for that session. The noise cancelling is pretty top notch, so I can't be mad at that. There's a little carrying pouch to stuff your muffs in when they're not in use. Not too protective yet effective. There's also 3.5mm aux cord available if you for some reason or another , run out of juice. And hopefully, you'll have a music player with a headphone jack to use it. But it's there if you need it. There's no real ambient noise option or noise pass through like other headphones in this price range. That's where I start my gripes. These are, for the most part, really good and well made headphones. Unfortunately, if you can shell out $200 for some headphones, you should go for a more complete brand. If you're giving them as a gift, don't tell them how much you spent and the recipient should be more than satisfied with them. And hopefully They aren't into name brands. All in all, these are a solid pair of bluetooth noise cancelling headphones, but they just simply cost too much. So, in good conscience, I can't recommend them.

[This review was collected as part of a promotion.] Sennheiser is one of those recognizable names that speaks quality. I find it no different with these HD 450BT headphones. There are lots of features that make these a great value and one that I would recommend to others for a great listening experience. The build quality on these headphones seems to be top notch. They are minimalistic and attractive looking headphones. They are light weight, yet very sturdy. They do fold down to a pretty small compact size. The hinges so far seem to be well built and I am not worried about them failing or breaking any time soon like I have seen on other folding headphones. These have a nicely padded headband and soft ear cups. Overall, these are very comfortable to wear for long listening sessions. I would note that my ears did start to get a bit warm after a few hours, but it was not enough for me to have to take them off and stop listening. Sound quality on these is fairly good and you do have the option to adjust the EQ settings in the app. They have a range of 18Hz-22kHz and a Total Harmonic Distortion (THD) of .3% which seems to be a good standard for these. I did feel the need to adjust the EQ settings right away, as out of the box, they lacked some brightness on the high ends. You can also create custom EQ settings so you can easily switch depending on the kind of music you are listening to. These do utilize Active Noise Cancelling (ANC) and along with a closed back design, works very well for sound isolation. Some of the great features on these are USB-C Charging – full charge in about 2 hours and an outstanding 30 hour battery life claim. I used these on a full charge for 3 full 8 hour days of work and they have not died yet. Simply awesome! These do come with a physical 3.5mm headphone cable for hardwired connection in case you do run out of battery. These do have a built in mic and the ability to be used for phone calls. I found the phone call quality was clear and I was able to use these for calls while working from home. There are a few things to take note of. The buttons are not labeled at all and I kept having to reference the user guide to use them until I was able to remember what buttons did what and where they were when I was wearing the headphones. These utilize Bluetooth 5.0 so be sure that what you are trying to connect them to is compatible. Other than that, these are a great pair of what I would consider mid-range headphones. I wouldn’t hesitate to recommend these to anyone looking for a nice pair of feature rich, nice sounding headphones.

[This review was collected as part of a promotion.] I got the Sennheiser HD 450BT Wireless headphones because of a recommendation that Sennheiser makes good quality audio products. I’ve never heard of the company before my research so I can’t speak to their legacy but these headphones are what I consider a mixed bag. As wireless headphones their audio quality is loud and clear which is really all you need in a set of headphones, so that’s great! The noise cancelling capabilities I felt were a little lacking, either on or off I felt like I was not hearing the world outside the cushioned ear pads. Speaking of the ear pads I’m not sure why they picked the narrow shape they did. You can see in my picture that rather than typical full circle pads the HD 450 headset uses narrow ovals, my assumption is that your ears aren’t circles but it was mildly annoying until I got used to it. Just an unusual pressure on my ear top, nothing to lose sleep over and I did eventually get used to it but I think I’d prefer the classic round design. The foam is thick and squishy so if you have smaller to medium size ears you should be fine and may not even know the difference, but my ears are a little large and that’s why I noticed. Another positive I liked was the way the two sides fold in and under the headband for compact storage. The other headphones I’ve owned would just stuff full size into a large bag or sit on my desk but the folding design of the HD 450 is super convenient! The headphones come with a zippered bag that resembled an old electric razor case and I didn’t think they would fit without some work but actually they slide in with room to spare and I was able to keep the instructional pamphlets in the pockets inside the case too. Very impressive carrying case set-up! However the downside to these headphones comes with the middle man of listening to music through them: using the controls to pair and adjust volume. These headphones do not label their switches and buttons! The instruction pamphlet gives you simple drawings to intuit which end of the headphone is which so you can then deduce which switch/button is the one to press for that function being described...however this was SEVERELY lacking in user friendliness! To me this is a deal breaker for me on headphones, I do not want to review a large folded map of instructions to figure out where the features I need are. Perhaps this is another “use it and get used to it”situation but whereas the narrow foam ears are a passive “get over it” the interaction with the buttons is something I shouldn’t have to think about. Overall I think these are good headphones, you’ll enjoy your music at great quality and volume with them but other than the folding storage the design of the Sennheiser HD 450BT headphones is bad. For me the sound quality can’t be enjoyed if I can’t adjust the volume, or even pair my phone with them unless I dig out a wad of instructions. If you’re the kind of person that can learn things without hassle then maybe these are the headphones you’re looking for but otherwise, if you’re like me, these will sit on your desk and you’ll just get a cheap pair of simple wireless headphones instead to save the complications and hassle.

[This review was collected as part of a promotion.] Great battery life. But the connectivity issues are so bad they make them almost unusable. If you attempt to use them between two devices. God help you. The app will tell me they’re connected and the Bluetooth settings on my iPhone will say the same, but alas…sound coming out of iPhone speakers. Then you have to go in and “forget device” and try the process over. The touch sensors are so sensitive, just grazing them on your shoulder could set them off. Can’t find anything in the settings to shut them off or change the configuration. Worst HP experience I’ve had in many years, maybe ever. Truly do not recommend, especially at that price point.

[This review was collected as part of a promotion.] Smooth listening, very light weight and comfortable. It swivel for easy comfort,really nice. Price is ok for quality. I would recommend.

[This review was collected as part of a promotion.] I got these on sale for $119 and I am very happy with my purchase. Comfort- Really comfortable, fits over my ears(male, avg head/ears) Sound Quality- Incredible sound quality, good app to adjust EQ Noise Cancellation - I would say when ANC is active, it cuts noise in half or more depending on the situation. If it's my Air Conditioner, I can barely hear it when I turn on ANC. If it is someone talking, their speech is cut in half. Really good for the price I think. Portability- Pretty portable, nice that they fold up. Buttons- some people say the buttons are hard to figure out... I disagree, it's pretty easy if you read the manual.

[This review was collected as part of a promotion.] The Sennheiser HD 450BT come well packaged. Opening the box you find the headset, storage case, AUX cable (2.5mm one side and 3.5mm the other side), USB-C cable, safety guide and quick start guide. You have everything you need to get started. As always, the first thing I do is give the headset a full charge. According to the manual the charge will last 30 hours. I have used it at least 10 hours and the charge is still full. According to the manual it takes 2 hours for a full charge. I found the quick start guide not as easy to follow as it could be. So here is a rundown of the functions on the right headset from front to back (see picture): 1. Power and Bluetooth pairing button. Hold for 4 seconds. 2. Receptor for the AUX cable 2.5mm side. Make sure you insert it all the way and turn to lock. I did not the first time and the sound is not great unless inserted all the way and locked. A cool feature actually to keep it secure. 3. USB-C cable connector. 4. Volume adjustment 5. Slide button. Listening to music: Press 1x press to pause a song. Forward to skip to the next song. Backward to skip to the previous song. Using the phone: 1x press to answer or hang up a call. Hold for 2 seconds to hold the call. 6. This has two functions as well. This will enable or disable active noise cancelling. This will also activate voice assistant (Siri, Google, etc.) Pairing the headphones was simple. All of the buttons are on the right headphone. The most forward button is held for about 4 seconds to pair the headphones. You will hear the voice tell you “power on – connected” every time you turn them on. Downloading the Sennheiser Smart Control app is recommended. With all electronics, you should update the firmware immediately. There are often new features or bug fixes in the firmware upgrade. My headphones came with v5.0 and I updated to v5.4 using the app. It took about 8 minutes to update the firmware. You can also set the sounds the way you like it using the equalizer feature. There are 2 choices: 1) use a slider to pick your EQ setting, or 2) use the traditional bands to pick you EQ setting. Now on to the listening experience. I find the headphones to be well balanced. The highs are crisp and clear and not to “tinny”. The bass is solid and punchy but not overbearing. Some bass junkies may want more bass. With the EQ I am sure everyone will find their perfect sound. I used the headphones for making some calls. The microphone is very sensitive and picks up your voice as well as other sounds. I was told they could hear me very well with no feedback or distortion. I found their voice sounded kind of hollow like I was in a large room. You can adjust the headband for a comfortable fit. These are snug on the head by default. I listened for about 3 hours straight before I noticed any uncomfortableness. For me, over the head headphones are rarely comfortable for long stretches. These were more comfortable than others I have used. With the Sennheiser name, you know you are getting a quality product. The build quality is solid as well as the sound and features. You can use them for phone calls but the sound was not as great as other headphones I have used. I rate these 4 stars due to the calling experience. From a music listening perspective they are awesome.

[This review was collected as part of a promotion.] I read many good reviews about the sound quality and decided to try this company for my next headphones. Suddenly, my Beats Studio 3 headphones were broken (due to really bad design quality), so I decided to give these headphones a try and I'm really glad about my choice. I give it 4 stars only because the headphones are smaller than Beats Studio; it's a really good product, but Beats was more comfortable – just that. I can recommend, if you have a chance to try this product in person, try it before buying.

[This review was collected as part of a promotion.] I am a member of Best Buy’s Technical Insider Network, TIN for short. Reviewers in this invitation-only program are provided products for the purpose of writing honest, unbiased reviews. Summary: The 450BT sound is crisp, clean, and bright. So bright that I had to turn down the treble and boost the base in the Sennheiser application. The ANC reduces constant ambient noise, such as a computer fan, to a little more than half. Sounds such as typing, doors closing, or cars driving by is reduced by a little but not enough to make my listening experience truly immersive. Hands free calling works well. The people I spoke with over the phone did not realize I was wearing a wireless headset that did not have a dedicated microphone boom. The controls on the right ear cup are useful, well placed, and responsive while connected too my phone over Bluetooth. Only ANC is functional when connected over the included stereo cable. The headphones are attractive and low profile. You can get away with walking with these on the street without looking like a dork. Construction is plastic, light weight, with stiff cushioning. The ear cups can accommodate any size head up to 9 inches from ear to ear. The head band is flexible and is covered with soft padding. The ear cups are smaller than on other headphones I have used at this price point. I have two issues with these headphones. First, the ear cups are too small for my ears. I am forced to push my ears into the back of the ear cups and then fold the ear cups forward to towards the front of my head to get a correct fit. Second, the ear cup padding is very stuff. I have TMJ. The padding puts enough pressure on my jaw that I cannot wear these headphones for more than an hour without discomfort. Please read on for the details. Sound: I started off with the K-Pop single “Pop/Stars” by K/DA, Madison Beer & (G)I-DLE. The very first thing I noticed was how weak the bass was and how bright the highs were. I immediately loaded up Sennheiser’s control app, boosted the base, and dropped the treble. This evened out the sound and brought it more in line with my personal tastes. I followed up with Momoland’s, “Boom Boom”. The base was punchy and fun. Next is a little-known track, “Train Wreck of Electro Swing” from the video game A Hat in Time. This piece if electronica and base heavy. Every sound was crisp, clear, and the base was punchy. I then switched over to Mega Death’s, “Holy Wars… Punishment Due” and “In my Darkest Hour”. The 450BT’s did a great job of representing the guitars, drums, bass guitar, and the vocals. These headphones held their own at all volume levels. Finally, I threw some classical to get a feel for how lengthy homework sessions may go. For this I chose Bach’s “Concerto in D Minor for Two Violins and Orchestra BMW 1043: III.” The violins high pitched violins were distinct and present. The 450BT’s did a good job of representing the orchestra in the background. Overall, I think these headphones did a good of reproducing a rather complicated piece of music. Setup: Setting up the earphones was easy. The very first thig I did was make sure they charged for two hours. Holding the power button for a few seconds put the headphones into sync mode. My iPhone had no issues picking up the 450BT and adding it to the Bluetooth wireless device list. A few seconds later I was listening to my favorite iTunes. I also set these up for use with my Windows 10 laptop. The headphones did protest a bit jumping connection from the iPhone to the computer over Bluetooth. The solution was to turn the iPhone’s Bluetooth off. I have other Bluetooth enabled headphones that swap easily between devices. The 450BT is inconsistent. I never have issues with the iPhone. It is switching devices that give me issues. Sennheiser’s Smart Control app allows for a single configuration item, the Equalizer. The 450BT allows for three adjustments: Bass, Mid, and Treble. There are two presets: Movie and Neutral. You can adjust the three sliders to your personal taste and then save that as a new preset. Personally, I think Sennheiser should have taken a little extra effort here to add a few other presets such as Rock, Jazz, and Classical. The app also reports the 450BT’s battery level and firmware version. Controls: First, the good. The button layout on the right ear cup will take a little practice to get used to. Everything works as advertised. The power button performs triple duty with the Bluetooth sync activation and the noise cancelation, or ANC. Then there is the volume control rocker button, forward/skip/pause switch, and the voice assistance switch. The right ear cup also houses two microphones, the stereo jack, and the USB charging port. The buttons are easily accessible, have good travel when pressed, and are responsive. Pressing any of the buttons immediately activate the corresponding feature on my phone. The same is true with my Windows 10 laptop. However, unlike my iPhone, I can only control the features available through the app I am using. For example, I cannot skip from one YouTube video to another using the skip forward/back features on the right ear cup. Finally, the only 450BT feature you can control while using the headphone jack is the ANC. Construction: The headphones are light weight plastic construction. Even the extension arms and ear cup holders are plastic. The ear cups are soft vinyl covering stiff foam. The head band is stiff enough to hold its shape and flexible enough to allow for larger heads. The head band expands to accommodate a space of about 9 inches from ear to ear. The ear cups are also on a swivel along the Y axis to allow for use with big hair or hats. You can get about 7 inches of clearance from the middle of the ear cup to the top of the head band in the right situation. The ear cups also swivel about 10 degrees forward and back to accommodate different head shapes. Finally, they have a little “L” and “R” molded into the decorative molding on the head band. They are hard to see unless you are looking straight at them. The controls are on the right ear cup. Why I cannot recommend these: The ear cups are too small. The padding is too stiff. The opening is 1-inch wide front to back and 2 ½ inches long from top to bottom. A child will probably do fine with the size and fit. Certainly not your average teenager or adult. If Sennheiser hallowed out the earcups then the comfort issues would vanish. As designed, the padding partially covers the speakers, forces the ear into an unnatural position, and puts undue pressure directly to my jaw’s joint which causes fatigue and pain. To illustrated the point, I load my ears starting from the back of my head, catch the back edge of my ears inside the ear cup, and then fold the earcups over my ears until the earcups rest flat against my head. The tips of my ears touch the speakers. I could wear these flat against my ears, however, these are marketed as over the ear and not on the ear. Also, wearing them flat is equally uncomfortable. I gave these to my youngest. This is most likely the age group these headphones are marketed towards. She gave me similar feedback to what I wrote above. She does not want to wear these headphones. All the positives of these headphones become irrelevant if no one in my household is willing to use them. I own other Sennheiser headphones and am very satisfied with them. The 450BT is not one of them. Human comfort needs to be front and center for headphones at this price point. And then everything else. Thank you for reading this review.

I've had these headphones for almost a year now and I can say that they have not been holding up to my expectations. The earpads, though comfortable, have been opening up on the inner seam. The noise cancellation feature is also a must for me, but that's because without it, it sounds like there's screeching audio frequencies in the background, which is then replace by very low almost white noise. The optional audio cable was also essential to me as sometimes when I connected my headphones just by Bluetooth to devices like my laptop there would be a significant audio stutter that could not be fixed by normal means. There's also issues with the Smart Control app that they get you to connect to.
