The Maono support team worked with me to trouble-shoot the problem with the device. These are fantastic, extremely comfortable & actually have arch support. With your noise cancellation on and connected to my belt loop the case allowed my AirPod pro case to fall out of the bottom of the case; which is the part that connects to the lanyard. I bought these for my daughter in law for Christmas, she loves them, the width is adjustable and allows you to custom fit the width. Yet, we know from physics that longer wire runs on an unbalanced cable (or even a balanced cable, to a lesser extent) degrade the signal. I?m very disappointed on how they can charge the same price for a knockoff. I use them wirelessly 5-6 days a week with NC on, drawing them down to 60-70 percent capacity. Ive been needing a new mouse pad for sometime now. I wear 8 or occasionally 8. Um den maximale Klang aus den kleinen Xelento herauszuholen, muss man sich intensiv mit den Eartips beschäftigen.
