No issues so far and they easily still fit the case and tap features work. I have only recharged it once in almost 3 months of regular use. Ill enclose a screen dump of the Typhoon read-out for this RAM so you can see what it says. These headphones offer great sound quality, a microphone to talk to friends on, and it also has control buttons which allow you to control volume+ mute both the headphones and microphone. For me, if I?m sweating, the stay in better. First I?d like to say that I love the FitFlop brand and I own a lot of them. I was supposed to be contacted by one of their "senior technicians" but instead they just decided to send me another replacement. Definitely sending them back! Thus, as I noted at the beginning, the HK Onyx Studio 5 is the speaker that most closely matches the way I like to hear music and wins the overall award. The thing I like the most is the depth of the drawers.
