Review: Great quality for the price u pay - Comfortable, looks good and has amazing sound quality with a decent mic Review: It was perfect, until it wasn`t - It worked great for several months. Sound is clean and well balanced. Not the best one, but still pleasing However after about 4-5 months something happened with Bluetooth connection and now it just makes some weird cracking noise instead of playing music. However when connected with a minijack, it plays the sound perfectly well. So I have no idea what specifically happened and how to fix it, but it doesn`t make me happy that this piece of gear isn`t that reliable on a longer run. ## Features - Bluetooth 5. 0 technology for effortlessly reliable connectivity including AAC and AptX Low Latency codec support - Active noise cancellation for uninterrupted listening pleasure - 30-hour battery life with USB-C fast charging - Intuitive controls including Virtual Assistant button for Siri and Google Assistant - Sennheiser App support providing an equalizer, Podcast Mode and Firmware updates - Included components: HD 450BT wireless headphones, audio cable USB-C charging cable, carry case, quick guide and safety guide ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083W7V3RG | | Additional Features | Fast Charging, Foldable, Microphone Included, Noise Cancellation | | Age Range Description | adults | | Antenna Location | Calling | | Audio Driver Type | Dynamic Driver | | Battery Average Life | 30 Hours | | Battery Charge Time | 2 Hours | | Best Sellers Rank | #45,057 in Electronics ( See Top 100 in Electronics ) #878 in Over-Ear Headphones | | Bluetooth Range | 10 Meters | | Bluetooth Version | 5.0 | | Brand | Sennheiser | | Built-In Media | Headband | | Cable Features | Without Cable | | Carrying Case Color | White | | Color | Black | | Compatible Devices | Cellphones | | Connectivity Technology | Wired, Wireless | | Control Method | App | | Control Type | Voice Control | | Controller Type | Voice Control | | Customer Package Type | Box | | Customer Reviews | 3.9 3.9 out of 5 stars (5,494) | | Earpiece Shape | Around Ear | | Enclosure Material | Plastic | | External Testing Certification | Não Aplicável | | Frequency Range | 18 Hz to 22,000 | | Frequency Response | 28000 | | Headphone Folding Features | Over Ear | | Headphone Jack | usb | | Headphones Ear Placement | Over Ear | | Impedance | 14 Ohms | | Is Autographed | No | | Is Electric | No | | Item Type Name | Headphone | | Item Weight | 238 Grams | | Manufacturer | Sennheiser | | Manufacturer Contact Information | OLD LYME, CT, 06371 US | | Model Name | HD 450BT Black | | Model Number | HD 450BT Black | | Noise Control | Active Noise Cancellation | | Number of Items | 1 | | Sensitivity | 14 Ohm | | Specific Uses For Product | Travel | | Style Name | Original | | Subject Character | no character | | Theme | Video Game | | Unit Count | 1 Count | | Water Resistance Level | Not Water Resistant | | Wireless Technology | Bluetooth | ## Product Details - **Brand:** Sennheiser - **Colour:** Black - **Ear placement:** Over Ear - **Form factor:** Over Ear - **Impedance:** 14 Ohms ## Images ![508386 Hd 450Bt Bluetooth 5.0 Wireless Headphone With Active Noise Cancellation - 30-Hour Battery Life, Usb-C Fast Charging, Virtual Assistant Button, Foldable - Black - Image 1](https://m.media-amazon.com/images/I/71z97HfSZxS.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: Where can I get another aux cable?** A: On Amazon. I recommend the marshall aux it has a great microphone and it has a coil which makes it very comfortable to be walking around without it getting caught on stuff or just not feeling like u have too much cable when working on a laptop. **Q: Is this recommended to use for online conferencing? is mic quality good?** A: Yes. I have used it for about 10 days for teams/zoom meetings, the mic and speaker work very well for me. **Q: Do they have transparent mode like more expensive models? And if not, is it possible to be reasonably aware of the surroundings when using them?** A: Answer to @ShakyJake, you mentioned that you are unable to turn it off the "Transparency Mode" or the pass-through sounds that are made ambiently around you, like voices, crinkling paper, and typing. This is not the same as ANC(Active Noice Cancellation) which removes only the ambient hum of the room like a fan, refrigerator, or airplane. This particular headset actually has two BlueTooth Connections or "drivers" on windows and mac. "Headphones (LE-HD 450BT Stereo)" & "Headset (HD 450BT Hands-Free AG Audio)" Mobile devices seem to auto-switch between these depending on if they are utilizing the mic in the Headset or not. Headphones (LE-HD 450BT Stereo): Does not utilize Transparency Mode, however ANC can be toggled. (Set this as "Default" if you do not want to here the Transparency mode) Headset (HD 450BT Hands-Free AG Audio): Seems to default Transparency Mode ON, and ANC can also be toggled when this is active as well. (If you make a lot of calls and utilize the mic setting this to "Default" may be more useful) If you use the Assistant button, this will automatically switch to this driver, but will revert if you have the headphones selected as "Default". **Extra Notes** If you have a 5.0 BlueTooth (internal or as an adapter) for your computer both of these are able to connect and you can toggle between these in your sound settings. Most modern mobile devices as of July 2016+ have this installed but you may use the AIDA64 app on the Google Play store to see if it's in your device. Apple Users: iPhone 8, iPhone 8 Plus, iPhone X, HomePod, and the 2018 MacBook Pro with Touch Bar all (and newer devices) utilize the 5.0 or newer BlueTooth. I do not know what happens if you have an older version of BlueTooth, however, I speculate that switching between the two drivers may be clunky, and slower than it already is. However they will still connect, you may just run into issues connecting other devices simultaneously like a mouse and keyboard. The S 450BT WILL usually prioritize headphone mode, however, I hope this helps if you were confused. If you use the Headphone Jack it will put the headphones in Flight Mode and deactivate all BlueTooth Connections. Hope this helps! **Q: Do the headphones come with a charger or do I need to buy one separately?** A: The headphones come with usb cable for charging, but no adaptor. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality for the price u pay *by Y***R on 19 September 2022* Comfortable, looks good and has amazing sound quality with a decent mic ### ⭐⭐⭐ It was perfect, until it wasn`t *by Y***V on 23 November 2023* It worked great for several months.
