It tells you charging progress. Ich liebe es. I intended to buy a pair of Slaps because Ive had two others that I liked, but they were not available. This one is no exception, with the added bonus that it sits very stable on my head, as over the years my hair has been thinning and normal headphones tend to slide of my head. I was hoping it would be a little tighter around the neck when zipped all the way up but it kind of droops even with the hood up. The C 214 is versatile and affordable, offering the user options and accessories to alter the mics performance. Like me. Owning 2 of them would be even better . I was expecting some of the similar limitations of ear bud speakers, Flooded bass levels buzzing and bleeding out the treble lines if turned up too loud. OR NOT.
