Not the loudest speaker or the deepest bass but for the size and price it is better than I expected. My child has worn them only a few times and the velcro has pulled away from the leather straps making it very difficult to un-do the shoes. But, theyre very well made and I doubt durability will be much of an issue. However, the double click issue plagues it like other logitech wireless mice. I am hearing things in my music that I havent heard before, and the presence of the bass is so natural and not harsh or hollow, it feels and sounds like a large speaker making real bass and not overdriving a woofer or some bass radiators like its competitors. having that option alone makes these worth any amount of ££££. Da sie innen jedoch nicht richtig gefüttert, sondern nur mit einer Art Fleecestoff ausgekleidet sind, halte ich sie eher für die matschige Übergangszeit und nicht für harte Wintertage geeignet. So to summarize:Yes it will be tight - its supposed to be. I havent tried the medium or large yet so I dont know if they fit as great in the case, but the small set fits perfectly. Actualización: pasados minutos después me di cuenta de que los dos earbuds tienen el mismo problema, y al agacharme se desconectan o se pausan,,???? asi no se puede,!
