They are super easy to use and the sound quality was great! Having invested so heavily on these headphones, I thought why not? And ordered FiiO E10K and Headphone Amplifier and USB DAC within the very same day of receiving it. With the more robust usb-c port and the fact there is no upside down anymore really make these worth a shot. If I do get too far, the quality drops for the first few words, then switches to a higher band and picks right back up. These are the staple trainer you need in your wardrobe. We will see. Et il n y avait pas. Wrong item delivered. -It fits on my iPhone 7, even though I use a case (its a slim carbon fiber case)-It charges with a lightning cable. and my heels and booties are in clear boxes on the shelf.
