The Sennheiser HD 450BT are alright wireless over-ear headphones. While they have a similarly sleek and decently built design as the Sennheiser HD 4.50 BTNC, they offer over 24 hours of continuous battery life which is outstandingly long. However, most other aspects of these headphones are okay and don't really stand out too much from their competitors. Their active noise cancelling feature has a fair performance but it struggles to reduce bass-range noise like bus or train engines. They also have a tight fit, helping them stay stable on your head during a light run. On the downside, their headband doesn't have a lot of padding and their ear cups may not fit larger ears well, which can make them uncomfortable to wear for several hours at a time.
The Sennheiser HD 450BT are okay for neutral sound. They have a slight overemphasis across the bass range and their treble is a bit dark. These headphones also have inconsistent mid and treble delivery, and their small ear cup holes can affect their seal on your head. Luckily, you can tweak their sound to be more neutral via the graphic EQ and presets on their companion app.
The Sennheiser HD 450BT are satisfactory for commute and travel. These bulky headphones have an okay ANC cancelling feature that can help cut a small bit of bass-range noise like bus or train engines, but it likely won't be enough for an ambient noise-free experience. Their headband isn't well-padded either and some users may find their tight fit uncomfortable. Their ear cups may not have enough space to fit larger ears without breaking their seal on your head either. On the upside, they have a good battery life that should last a long travel day.
The Sennheiser HD 450BT are satisfactory for sports and fitness. While they're a little bulky, they're stable enough to wear for a light run or jog. Thanks to their wireless design, there's no audio cable to snag on something and yank them off your head. However, some users may find their fit to be a little tight or that the headband feels uncomfortable. More rigorous physical activity can also knock them off your head.
The Sennheiser HD 450BT are decent for office use. They have a tight fit and some users may find the headband or the ear cups uncomfortable, especially for long listening sessions. That said, they have an okay ANC feature which can help cut down office chatter, and they don't leak a lot of sound either. They also have a very long battery life so you don't need to worry about your headphones dying before the end of your work day.
The Sennheiser HD 450BT aren't recommended for wireless gaming. They're Bluetooth-only so they aren't compatible with Xbox One or PS4. While you can connect them to a Bluetooth-enabled PC, the latency will likely be too high for gaming.
The Sennheiser HD 450BT are satisfactory for wired gaming. If you only want to hear your game audio, you can plug them into a PC or into a PS4 or Xbox One controller but you won't be able to use their mic. They have a balanced but dark sound, and you can use their companion app to further customize its sound via its graphic EQ and presets.
The Sennheiser HD 450BT are mediocre for phone calls. They use an integrated microphone but while it can capture the depth of your voice, it sounds noticeably muffled and lacking in detail. It also has a lot of trouble separating speech from even moderately noisy environments. On the upside, the headphones have an okay noise isolation performance and their ANC feature can further help to reduce noise around you.
The Sennheiser HD 450BT are very non-descript-looking headphones. While they're fairly similar in look to the Sennheiser HD 4.50BTNC, they don't have a silver ring around their ear cups. They also come in a white variant if you prefer a different look.
The Sennheiser HD 450BT have a satisfactorily comfortable fit. While they feel fairly lightweight, some users may find it a little tight due to their high clamping force. The headband isn't thickly padded either, which can be uncomfortable when worn for multiple hours at a time. The ear cups' holes are also somewhat small, and it can be difficult to put your ears into, especially if you have larger ears. On the upside, the faux-leather padding feels nice on the skin. If you want an even more comfortable pair of headphones, consider the Sony WH-CH710N Wireless.
The Sennheiser HD 450BT have okay controls. They're not the most intuitive to use and there's not a lot of voice prompt feedback to know which controls you're changing. There's a voice assistant button, a call/music management rocker, and a volume toggle. There's also a multi-function button that turns on/off ANC, power, and pairing.
The Sennheiser HD 450BT are passably portable. They can fold up to save a bit of space and they come with a carrying case, which is handy. However, they're still big and bulky headphones that can be a little difficult to carry with you on your person.
The Sennheiser HD 450BT come with a soft case that doesn't really do much to protect the headphones from impacts or drops.
The Sennheiser HD 450BT have decent build quality. They're mostly made of plastic but they feel sturdy, especially as they're designed to fold into a more compact size. A rubber-like material coats the headband, and the ear cups have faux-leather padding. They should be able to withstand a few drops or accidental bumps.
The Sennheiser HD 450BT Wireless have good stability. They clamp fairly tightly on the head, but they may fall off with big head shakes, so they're not the best choice for more rigorous physical activity.
Their sound profile is balanced but a little dark. They've got just a touch of extra bass, which fans of EDM and hip-hop can enjoy. That being said, they're well-suited for a variety of audio genres, such as podcasts or classical music. If you prefer a different sound, their companion app includes a graphic EQ and presets.
The frequency response consistency of the Sennheiser HD 450BT is mediocre. Due to their tight fit and the small holes for their ear cups, the padding of the ear cups doesn't necessarily lay flat on the head, which can result in an inconsistent mid to treble delivery. If you're looking for over-ear headphones that deliver sound more consistently, consider the Samson SR850.
The Sennheiser HD 450BT have great bass accuracy. It's just a little overemphasized across the range but it's even, resulting in a thumpy sound. However, some listeners may find it to be a little too boomy.
The mid accuracy is excellent. It's well-balanced and accurate, ensuring the clear reproduction of vocals and lead instruments. However, these headphones have a somewhat inconsistent mid-range delivery that's reliant on fit and positioning. Thus, this mid accuracy performance represents the average response and your experience may vary.
The Sennheiser HD 450BT has disappointing treble accuracy. It's quite underemphasized across the range, resulting in a dark and veiled sound. However, this treble accuracy performance represents the average response and your experience may vary.
The Sennheiser HD 450BT's peaks and dips performance is decent. Just like the Sennheiser HD 4.5 BTNC, there's a peak in the high-mid that descends into a dip in the low treble but it isn't as severe. It makes vocals and lead instruments sound honky and harsh while lacking detail and clarity.
The Sennheiser HD 450BT have alright imaging. The GD graph shows that the group delay has a few spikes in the low-bass range but this shouldn't be noticeable to most listeners. There's also a bit of amplitude and frequency mismatch in the L/R drivers, which may affect the placement and localization of objects such as voices, instruments, and sound effects in the stereo image. That being said, these results are only valid for our test unit, and yours may perform differently.
The Sennheiser HD 450BT's passive soundstage is poor. As these headphones have a closed-back design, they sound less open than open-back headphones. Overall, their soundstage is natural but somewhat small, so sound will be perceived as being located inside your head instead of out in front of you.
These headphones don't have any virtual soundstage features.
The Sennheiser HD 450BT's weighted harmonic distortion performance is decent. There are a couple of spikes in the treble range which appear at both a normal volume as well as max volume. However, it likely won't be too noticeable to most people.
These are the settings used to test these headphones. Our results are only valid when using these settings.
The Sennheiser HD 450BT have an alright noise isolation performance. Their active noise cancelling feature only manages to reduce bass-range noise. However, it's still pretty poor at cutting down noise like bus engines and may not be enough if you commute a lot. That said, it does a better job of reducing mid-range noise like chatter and treble-range sounds like the hum of an A/C unit.
These headphones have a great leakage performance. While their leakage sounds fuller than that of in-ears or earbuds, it's quieter than the noise floor of an average office, so you can listen to audio at a high volume without bothering those around you too much.
The Sennheiser HD 450BT have an integrated microphone.
The recording quality of the mic is disappointing. While your voice sounds natural, it sounds noticeably muffled and lacking in detail. If you want wireless over-ears with a better mic performance, check out the JBL Tune 760NC Wireless.
The noise handling of the microphone is disappointing. Your voice gets lost, even in only moderately noisy environments.
The Sennheiser HD 450BT's battery performance is good. The manufacturer advertises a continuous playtime of 30 hours with only a couple of hours of charging, and even with the noise cancelling feature on, our tests are nearly able to match it. However, while they can be used passively, you won't be able to listen to them while they charge.
Sennheiser Smart Control is a just satisfactory app. It has a very limited parametric EQ as well as a three-band graphic EQ. You can also check for firmware updates, as well as see the battery level but that's about it.
The Sennheiser HD 450BT have great Bluetooth connectivity. While they don't have NFC pairing, you can connect them to up to two devices at a time, which is handy if you like to use your headphones with your laptop and phone. They have an outstandingly long line of sight range. However, they have high latency on PC and iOS when streaming videos. Their Android latency is much lower, though. That said, some apps and devices compensate for lag so your real-life mileage may vary.
These headphones are Bluetooth-compatible.
These headphones come with a 1/8" TRS audio cable. It doesn't have an in-line mic.
The Sennheiser HD 450BT are audio-only compatible when plugged into an Xbox One controller. You won't be able to use your microphone, though.
The Sennheiser HD 450BT come in two color variants: Black and White. Although we tested the black variant, results should be valid for both colors.
The Sennheiser HD 450BT are fair wireless headphones. They have an ANC feature that doesn't really stand out too much amongst other ANC headphones, especially as it struggles a bit more to cut down bass noise. It also has a very tight fit, and similar to the Sennheiser HD 4.50 BTNC, its headband is only lightly padded, which can be uncomfortable for some users, especially during long listening sessions.
