Yes, Sound Cancelling Headphones is one of the highest selling item in world ! and every-time you look at the headphone specifications you might have came across a term Noise Cancelling Headphones featuring CVC 6.0 Noise suppression !
I think it is necessary to know meaning of cvc and its utility and is it MUST for my headphone ? if yes in what way.
So here is my research where I will be explaining you cvc6.0 noise reduction term in details.
Why you need Noise Cancelling for Headphones?
Either you are using the headset at Home or Outdoors, different environment noises disturb your, specially during calls making conversation difficult at times. Mostly person at the other end of call will hear roar, disturbing noise which will be filtered by this intelligent system.
If you are at home, you get background noises of Air conditioning, Washing machine, Children playing, Someone who is watching a TV, Cooking and so many.
If you are at Outdoors, you get other background noises like Wind noise, People crowd buzz, Passing-by cars tire roar, Boom of jet engines, which makes your phone calls on through headphones extremely difficult!
So What’s the solution? CVC by Qualcomm ?
It is one of the best & most affordable system making telephonic conversation over your headphone super silent ! In simple words, the person at the other end of call will feel like you are talking to him from a quiet indoor space ! Wonderful technology making call quality super in the cheapest entry level earbuds & headphones. Thanks to Qualcomm engineering research center for that.
What is CVC 6.0 Noise Cancelling Technology?
CVC noise cancellation technology by Qualcomm works in the background providing you Audio Enhancements and Noise Suppression to the near and far end.
CVC provides packet loss and bit error concealment.
In tern, CVC noise reduction ensures Best possible call conversation quality on your Bluetooth headsets, Landline Handsets, Hands-free Devices and other Automotive Communication Devices.
How cVc noise cancellation works?
During voice call, the microphone picks up all background noises as well as your voice too, in this scenario, CVC intelligent algorithms comes into picture, they will Enhance the Voice Quality during transmission from your headset, as well as do the same during reception at the other end headphone (if that headset is CVC enabled)
Further to this CVC noise reduction consists of modular suite of algorithms that works on:
Enhancing voice communication : Crystal Clear Sound output
Examples like acoustic echo cancellation and noise suppression, which can be applied in a granular fashion to as per the customized requirements of the gadget.
CVC separates out the voice signals of interest:
Other logic or algorithms in market which are used to suppress noise, CVC uses proprietary signal extraction techniques, it understands the way human speech is heard and processed! and employs an active and self-adaptive system.
- Automatic gain controls
- Send/Receive equalizers
- Comfort noise
- Howling control
- Nonlinear processing
- Adaptive equalizers
- Power savings techniques
- Auxiliary stream mixing
- Frequency enhanced speech intelligibility

Now finally Qualcomm vs Apple Bluetooth headphones
Apple directly sells products to the end consumer and has strong brand image behind them.
Qualcomm works in the background and does not sell their products to the end consumer, however over years now consumers are aware of Qualcomm and their hardware power !
Apple doesn’t support the high sample rates or 24-bit audio, their AAC codec is limited to just a 264 kbps bitrate, which is a lower transfer rate than aptX, aptX HD, and LDAC. But at the front end you can directly stream files from AAC-based services like Apple Music. However I think Apple isn’t thinking on getting the truly high-end specifications that often catch headlines in audio world.
Well, Qualcomm’s Broadcast Audio technology runs on a number of of its audio SoCs for speakers, and now on Snapdragon 845. The company’s latest TrueWireless Stereo Plus gaining benefit of 10 percent power savings.
Both Apple as well as Qualcomm are working on Bluetooth enhancements which are required for the latest smart home speakers, which needs internet connectivity, casting support, voice keyword detection, multi-microphone input support, and noise cancellation technologies ! This demands complex hardware & software’s pushing on more efforts in R&D time & cost. Well other companies instead of spending time & money, want to buy more cost effective Qualcomm solutions for their smart speakers so that they can focus on the audio circuitry and acoustic design.
Finally Qualcomm will be help normal consumers providing a wider range of productss at various price points, ranging from cost effective headphones to top notch audiophile brands that have a far better reputation than some of the Apple products !
