Like other Audi owners, we are disappointed Audi doesnt have the capability for drivers to connect their music through a USB port in the arm rest or connect via Bluetooth. At least externally. I am even still using it even though I found the original charging cord. I’m 54 I bout broke my neck in them their an inch off the ground and it would cause me to twist my foot sideways as I walked. 33 more per pair (list price) is nicely cushioned in the heel, softer to the touch and the inner hem is not noticeable. The pump itself took me 10 minutes to pop up. TL;DR,Audio: 4. Keep doing the great job Guy @iFox Router bits go in and out perfectly but have enough snug on them to keep them secure. There is a distinct improvement in midrange and treble response between the two, and overall this little speaker is amazing.
