So these are the Bose QC Ultra Earbuds… now they have some minor upgrades over the Bose QC Earbuds 2, which are all found under the hood. But the Bose QC Ultra earbuds have the same case and shape as their predecessors… which for me is a big drawback cause I think their case is just too big. However, I have come to appreciate the Bose QC Ultra earbuds because of their comfort. So lets see if the Bose QC Ultra earbuds are right for you and lets see if its worth upgrading if you already have the Bose QC Earbuds 2.
