Sound is very very good. The ANC is actually quite noticeable, and blocks out my washing machine and dryer sounds well. I havent used them yet, waiting for a curtain rod to get here which these will be used for. I wanted to use it on my ride but Im scared to death of it failing off. Can control phone features such as voice control, call answering, track selection and volume control. We were lacking space to hang dry clothes in our new laundry room. The M70x comes with a hard carrying case which shields it during transportation and is noticeably bigger. I took it down the highway with the J Hooks and kayak on the top and this thing felt as sturdy as an OEM rack. I havent used it extensively for phone calls, but I did try one and the party at the other end said quality was fine; sounded OK at my end too. Other than the sizing being a half-size too small .
