Bests & Worsts Reviews from Amazon

I have enjoyed this product : great comfort and great sound. I had the previous version and hesitated to buy this one due to multiple complaints over thinner wires and the the replacement of the T connector with a straight one ( see attached picture). At around month 11, I lost sound on the left side. The issue is as suspected above, at the base of the connector: there is no visible sign of damage or wear and tear, but the sound comes back to the two ear pieces while bending the wire gently at the wire base. ( see attached picture). My previous Bose in ear Ultra still works, which is a small consolation. I also have two Bose radios with an impeccable quality over decades. Bose means good sound and quality to us. That said, it seems that Bose lowered the durability of its in ear headphones by replacing the T connector and making the wires thinner ( there is slight but noticeable electrostatic noise when the wire gets close to my strap heart rate monitor). Now is my time to assess Bose user warranty... will update this post when warranted
