Both the headphones share the Sennheiser signature sound, with lows spanning from just 18 Hz, you can simply feel the punch in Bass … Mids & highs till 22 kHz can cover the Vocals easily, I don’t think going beyond that is much fun though technically desired for.

What’s difference in Sennheiser HD 4.40BT vs HD 4.50BTNC

These days world is becoming quite noisy around, be it that you are parenting the children in the park, travelling for office work, or even during air-travel (noise of the Jet propulsion), things keep on disturbing you always, making you anxious, restless. Even if you wish to listen to your favorite music becomes a pain. With introduction of Active Noise Cancellation, the scene is completely changed, life has become quieter, making you yourself 🙂

Looks like Sennheiser has rightly understood this need and introduced this feature in all new HD 4.50BTNC.

• NoiseGard™ active noise cancellation
  HD 4.50BTNC features NoiseGuard™ Active Noise Cancellation, researched to the depth of demanding music lovers like you, making sure you just listen to pure music and nothing else 🙂 Forget the environment, no matter where you are, the NoiseGard™ will take care of unwanted noises in the surroundings, So that no one disturbs you….. It’s only in between you and your music 🙂
  Note : You can also switch the NoiseGard OFF by by pressing both volume buttons simultaneously

• Battery Life & Quick charging
  the new HD 4.50BTNC are also backed-up by powerful Li-ion Polymer Battery, combined with low-power Bluetooth technology,  it can deliver 25 hours of music, which remains same as the HD 4.40BT
  Remember the life of 25 hours is with Active Noise Cancellation OFF, obviously when using the NoiseGuard™ active noise cancellation technology the battery life reduces to 19 hours ! still very good I would say.
  Looking at the recharging of battery, it happens in just couple of hours ! looks cool !!

What’s Common in Sennheiser HD 4.40BT vs HD 4.50BTNC

• Ergonomic & Intuitive Music controls
  Lets begin with something which is the basic strength of your BT headset, the music controls, you have to use them now and then, and it is most important to have them ergonomically reachable & operable, as well as intuitive. Both HD series headphones features ear-cup mounted controls with the integrated microphones for making audio calls, switching the sound-tracks.
  [They feature the power button, multifunction button and volume button on ear-cups]

• Long lasting comfort with around the ear design
  Around-ear design & softer ear pads let you wear them for longer duration without fatigue.

• AptX – CD Quality Sound Output
  Both the HD 4.50BTNC and HD 4.40BT uses Bluetooth 4.0 and AptX, ensuring high-quality sound output.

• Bluetooth & NFC Wireless Pairing [Near Field Communication]
  A long press of @2 seconds of the power button, makes the headphone visible to your phones Bluetooth, simply select and pair 🙂
  NFC further simplifies your life by quick pairing with NFC compatible devices like Mobile phones, simply bring the Mobile phone and headset very near to each other and they will pair with each other, murmurous guidelines are available on NFC, just Google for it.

• CapTune App support for iPhone & Android
  Sennheiser  has their own CapTune App for Apple iPhone and Android useful for your HD headphones. Use it to stream music directly from you library.
  Headphones remaining battery life indicator on mobile is very useful feature you get with this App.
  Add on bonus will be the custom equalizer settings and savable profiles.

• Backpack compatible – Foldable
  One more important thing in both these headphones is the portability, both are foldable and can be packed on the go, so quickly goes into your backpack 🙂

Where Bose Quietcomfort costs you $300 to $350, At price-point of $200 with NC feature, Sennheiser HD Series are top headphones in 2017, for sure it looks an attractive proposition.

[Prices are indicative shown based on information on the date of writing this post, readers are suggested to check online prices please]

I suggest you to ignore very slight hitch of less comfort as compared to the Premium quality  high end BOSE or Sony models, remember you are spending significant less amount to get all that you want 🙂

Obviously if you don’t need Active Noise Cancellation then select for Sennheiser HD 4.40BT and if you are vivid traveler and really in dire need of  comfort of quietness, go for Sennheiser HD 4.50 BTNC
