Well Airpods, Bose ect are utter rubbish as your mainly paying for the name and thats why I prefer the sound from my £40 cheapy earbuds. My headphones that uses SBC codecs sound dreadful compared to my earbuds but thats the headphones fault more then the codec, as the sound is very muggy,, basically too bass where there shouldn't be any..
Those cambridge buds have really good reviews and even a "WHAT-HIFI" 2020 award, so I might try them, plus they sound like the antenna is good if they say "SUPERIOR CONNECTION: the very latest true wireless Bluetooth 5.0 technology to ensure no drops in signal, and connectivity at up to 30 meters." So they might work better in my house.
