I have owned and listened to many wireless earbuds and as such am able to to compare these with some of the best currently on the market
The Kef Mu3 are brilliant!
Sound wise in my opinion the best of the best. Clear, detailed table and midrange and have great bass ( without being over bloated)
I Can listen to these comfortably for hours.
The buds themselves are are perfect in size, ( discreet as they are not large or bulky and extremely comfortable for in ear buds)
Good ANC very easy to use and great battery life
