I was given one of these as a Birthday present last year, and having a B&O earset which I prefer, I later ( and quietly ) gave it to my one of my sons. He said it required about one day to learn the technique of turning it on and off, and apparently it needs to be turned off manually to charge. Luxury: Not really, but it is distinctly a B&O design, and it works.
He did ask for the " loan " of an A-8 earpiece cover, stating that it helped to keep the earpiece in his ear.rather than flopping about in the wind. ( We have now learned that when your children are University students, everything needed is " a loan " ).
