Are all over the map. My answer is that email fails too often.
But to your earbud question. There is a mega-thread on another model and the interesting to me answers was about wax buildup in the buds. Go ahead and say Eww but yup, that does happen. Not a design flaw.
My right earbud started to lose volume about a month ago. After putting the earbud in the volume was normal but soon the sound volume became less and less. At first it made it about 10-15 minutes but over the next few weeks it dropped in volume in much shorter time. Now, about 6 weeks have gone by and it’s lasting 5-10 seconds once I pop it in my ear and I can only hear sound from the left earbud. I have to say that I rarely used my left earbud prior to this fo a number of reasons. I hope someone may have found a fix for this issue. Also, I’ve emailed Jabra a few weeks ago and I haven’t heard back from them. Is that also normal? Thank you.
