Afaik, most premium wireless earbuds are tuned for music enjoyment. A Few are tuned for phone calls. In that case, What’s your percentage of Music vs Calls on wireless earbuds?
if you use it for calls quite often, then you might wanna other brands such as Earfun, Soundcore and Soundpeats which place much emphasis on using good NOise cancellation tech and call mics to deliver good call quality
for Noise cancellation, afaik, there are two types
1) ANC (Active noise cancellation) which most of us have come to know
2) phone call background noise reduction. This has several names like ENC (Environment Noise Cancellation), CVC (Clear Voice Capture), RCV (Real Clear Voice)
For controls on ANC and Transparency…this is totally dependent on the company.
for example, SONY, Bose and Sennheiser have their own apps which allow users to have deeper controls on ANC and transparency levels
Since I am a Sony headphone user, the Sony app also come with several preset environments such as TRAIN, HOME, WORKPLACE, which has different ANC level settings.
Multi-Bluetooth connection allows your bluetooth wireless earbuds to be connected to several devices at the same time BUT BUT BUT it only allow audio streaming from ONE DEVICE at any one time.
If you want L earbud to stream music from your phone and R earbud to stream ZOOM calls from your laptop, there is one wireless earbuds product called GENKI in Kickstarter (I am waiting for the shipment)… you can check it out
once I received it, I will do the review and test this “Multi Bluetooth audio Streaming” feature
