Great Sound. Shipping was ultrafast.

not Certified Refurbished at all used like someone returned it after using it for months.

Initial thought was pretty bad because when it came, it looks like it was still registered under someone else and is trackable. No instructions on how to remove previous owner. Had to reach out to Sony for direction. Otherwise, it’s a great little bud.

The battery barely last 2 hrs…

Item arrived in great condition and functioned without any issues. Packaging was very sparse, just a clear plastic bag, but everything was included (cable, extra tips, etc.). The only reason that I dropped a star is that there was no documentation included, and I had to read manuals that were easily found and available online. My total after tax, shipping, coupons, etc. was $45.27, and the features and performance of these buds, especially when used with the free, downloadable phone based app, are WAY above the price. Noise cancelling, battery life, microphone quality for calls, fit in ear, comfort during long use (hours), multi point pairing, voice commands and activation, and features of the free app were all better than I expected. It took some effort to get it all right, but the end result was worth it. If you can achieve a good seal in your ears, the sound quality is very good for wireless bluetooth.
