I've been a Bose fan for many years and have owned various products that are really good quality and have lasted. However, the rubber on the original SSF is an exception to that and is
a common issue but Bose has not owned up to it. The left side of mine have broken off and the way they designed it is with a plastic piece under it so now I can't activate the button on my left bud. Fantastic sound and I really enjoyed them and had been considering their Sport or QC but am now hesitant as I'm concerned they're using the same rubber formula.
Aside from the bug you mentioned, their Bluetooth implementation is quirky on a few of their devices; even though they're supposed to be "off", I always see the SSF and the Revolve+ as being available for pairing (not so with their 700 at least).
This isn't meant to be a rant, I'm still enjoying a bunch of their products - just sharing experiences FWIW.
