These sound GREAT for an earbud. THE BASS! But, they are not a quality product. Not Woot’s fault, or the refurbisher. Bose just failed to achieve on this one. I bought a refurb set here, they only lasted about two months before they quit charging (first the firmware started acting real buggy for a couple of weeks). I had liked the sound so much that I bought a new pair from Amazon. They lasted about 5 months. Same issues. If you like the tethered earbuds (I don’t ever want to put one single additional thing in my pocket, ever!) I totally, wholeheartedly recommend Soundpeats.
Bought two sets of these in the past from woot. Both refurbished, and still work great after a year. Maybe the best sound from others I own.
