Which headset and earbuds models are tested best for Active Noise Cancellation?

[@HEADacousticsInternational]

We do not advertise headphones - We develop the proper equipment to test them 😊
Here’s a video from The Verge who have used our equipment, our facilities and our support to answer your question:

Maybe you being an expert in the field of ANC can help me a bit in understanding my problem. In the last year I have bought about 6 earbuds and headphones with ANC that are widely considered as best one currently in the market. According to different publicly available measurements of ANC in this headphones they all vary wildly in performance. Some are claimed (based on measurements) to reduce on average 20db of noise below 1kHz, some 30db, some even 40db. But to me they were almost identical in the real life situations. I had hard time differentiating between best and worst headphones. What may be the cause of that?

Great question - and one that highlights some of the potential pitfalls of “marketing” and potentially non-standardized testing and reporting. Your products state an average noise reduction of x dB below 1kHz, but they do not state:
1) What testing methods or technologies were used?
a. Did they use a state-of-the-art background noise reproduction system (compliant to ETSI TS 103 224) and a Head and Torso Simulator with ITU-T P.57 4.4 ears?
b. What background noise source material was used? (Pink noise? Airplane cabin noise? Pub/cafeteria noise? Etc.)
2) How the results were derived? Are they just calculating overall levels and subtracting them? Are they subtracting spectra and then levels?
3) What is the frequency based attenuation?
a. Where does peak attenuation occur? If peak attenuation for one device occurs at 50Hz, vs. say, 200Hz for another device, the same dB value for attenuation will be perceived very differently - simply because the human hearing system is not as sensitive to noise at 50Hz.
b. How steady/stable is the attenuation across frequencies 1kHz is generally dominated by the passive components)
Using HEAD acoustics tools and techniques can answer all those questions and leave no doubt about the noise cancellation performance of your device(s).
Hope that helps - and appreciate you watching the video! 🙏

@@HEADacousticsInternational Thank you for the answer, I really appreciate that. I also liked your collaboration with Verge regarding ANC headphones. I am especially glad that you released technical report from ANC measurements that accompanied Verge video. I hope that in the future you will be releasing more of this kind of consumer friendly reports about ANC headphones, they really make a difference.
