Reasons Why You Should Buy Them

  • Sennheiser HD 450BT is a pair of good sounding headphones with detailed and clear sound stage. The 32mm dynamic drivers deliver tight and powerful bass, detailed mid-range and controlled treble to ensure a pleasant sound reproduction
  • Decent noise cancellation that blocks most external sounds, especially low frequency, so you can enjoy your favorite songs without distraction
  • Most travelers find these headphones as a good companion when traveling because of their foldable design, which makes it easier to store them in the little travel bag they come with
  • Their lightweight construction (thanks to the all plastic design) and thick ear cushions make them quite comfortable to use even for long listening sessions
  • Bluetooth 5.0 and superior codec support such as AAC, aptX and aptX Low Latency for seamless connectivity and better audio quality
  • On-board microphone and physical controls let you answer phone calls, skip tracks, play/pause music, adjust volume, power on and off, turn ANC on and off, and connect to Google Assistant or Siri
  • Battery life of up to 30 hours on a single charge is quite impressive and good enough for transatlantic flight without looking for a power outlet
  • If the battery runs out, HD 450BT can still be used in passive mode with an analogue connection via 2.5mm - 3.5mm audio cable (included in box)
  • They offer a respectable call quality (better than some other supra-ear models), people at the other end of the call can hear you clearly in moderately noisy environments
  • If you're looking for a pair of affordable noise-canceling headphones, they check most of the boxes because of their build quality, features and relatively good sound quality

Reasons Why You Should Avoid Them

  • They are not recommended for people with large heads or who wear glasses. They may be a little uncomfortable due to the strong clamping force
  • The noise cancellation is good to suppress the low frequencies, but not the high ones. This means you can hear sirens and engine sounds as you walk through busy city streets
  • The Sennheiser Smart Control app is pretty basic and lacks many useful features. You can perform an EQ adjustment (this is unreasonably complicated), check the battery status and receive over-the-ear updates, nothing else
  • The all-plastic structure (definitely helps save weight) and cheap quality ear cups padding prone to damage under moderate physical stress
  • No "auto-pause" function when you take them off, which means that the next time you use them, you will have to jump back the title
  • There is no ambient noise mode that keeps you aware about the surroundings as you walk through the busy city streets or listening to important announcements
  • The HD 450BT's sound stage could be more open, the other Sennheiser models, especially the Momentum Wireless 3, have a wider sound stage that makes them ideal for watching HD videos as well
  • There is no way to regulate noise cancellation levels; You can only turn it on and off with a dedicated on-board button
  • Only two colors are available: Black and White, they look great but young people prefer bright and vibrant colors that match their styles
  • The included soft case looks good but only protects against scratches, not falls and water damage

Highlights

  • The rechargeable battery offers up to 30 hours of music playback on a single charge
  • Active noise-canceling technology to completely eliminate external sounds
  • Built-in microphone for hands-free communication via a compatible device
  • Bluetooth 5.0 for seamless wireless connection to your Bluetooth-enabled device
  • Over-the-ear design for a safe and comfortable fit during long listening sessions
  • The collapsible design along with the included carry case allows easy mobility
  • The frequency response from 18 Hz to 22 kHz ensures true-to-original sound reproduction
  • Sennheiser app support with equalizer adjustment, podcast mode and firmware updates
  • Intuitive on-board controls, including the dedicated voice assistant button to connect to Siri or Google Assistant
