The only complaint that I have with the A4000 would occasionally be the fit. They come with a charging cord, a dual-sided aux cable, and a reliable carrying case. And combined with the Airpod pros, the sound isolation is stellar, significantly better than the silicone tips were. Wear all day and be comfortable. They are unobtrusive to others and dont scream "look at me" as other dangling white earphones do. I failed on the first attempt, but luckily they included two. It?s very useful and very sturdy to take the weight of 30-40 pairs of footwear. Would not recommend this one. Bloated and this product fit me perfectly. Seeing how I used my QC headphones so much that I wore out the pads, these aren?t a bad substitute.
